Design of 4 Line Private Exchange Box

Design of 4 Line Private Exchange Box INTRODUCTION 1.0 INTRODUCTION Private branch exchange system (PBXs) operates as a connection within private organizations usually a business. Because they incorporate telephones, the general term extension is used to refer to any end point on the branch. The PBX handles calls between these extensions. The primary advantage of PBXs was cost savings on internal phone calls: handling the circuit switching locally reduced charges for local phone services. The private branch exchange (PBX) provides internal station-to-station communications for a well-defined set of users. Three distinct generations of private branch exchanges have appeared. In the first generation (1900-1930), a human operator manually set up calls. Second-generation private branch exchanges (mid-1930s to mid-1970s) used mechanical relays to establish the call path. The third generation of private branch exchanges is the stored-program microprocessor-controlled system. Introduced in the mid-1970s, these systems use computer instructions to perform th e call set-up and tear-down. The third-generation private branch exchange is physically much smaller than electromechanical models, uses less power, and generates less heat.(Brooks, 1999) In this project, the design of a 4 line telephone systems with full signaling and switching functions similar to those of the central office systems was embarked upon. Dial tone, busy tone, and ring tone are provided during call process. Switching employs integrated circuit (IC) matrix switches on four buses. Thus, this system is expandable to 8 lines (4 pairs) if more hardware is added. This system is switching on the Dual Tone Multi Frequency (DTMF) dialing signal. 1.1 STATEMENT OF PROBLEM The major problems this project intends to deal with are: Cut down cost of internal calls made within a company. Eliminate the need for a central telephone company to help you monitor your internal calls. Eliminate Stress of notification of telephone company each time you need a new extension and thereby reducing cost. Ensure security of your internal calls which otherwise can be tapped by company operating it. Eliminate the need for a manual switchboard and subsequently an operator to connect the calls. Reduce man-hours lost through staff walking about in an office in order to pass information to each other. 1.2 AIMS AND OBJECTIVES: The main aim of this project is to design and implement a 4 line private exchange box that is able to create connection between four different telephone lines internally without having to connect to an external or trunk line. The objectives include: Establishing connections between the telephone sets of any two users. (e.g. mapping a dialed number to a physical phone) Maintaining such connections as long as the users require them. (i.e. channeling voice signals between the users) Creating an easy means of communication in an office without getting to spend money for their internal calls. To switch between telephone users thereby creating connections. To make sure the connection remains in place as long as it last, by keeping its resources. To properly end the connection when a user hangs up. 1.3 SIGNIFICANCE OF STUDY The ability or concept of providing an easy and less expensive way of communication within a small office or organization without having to pay for your internal calls or having limits to the rate or length of calls within the office. Also it is not necessary to go from office to office when something is needed, information is to be passed; a call to a colleague saves stress of walking about. 1.4 SCOPE OF STUDY The Private Exchange System in this project is limited to a four lines which means that internal calls can be made from only four nodes. As such, it is only suitable for very small organization. 1.5 RESEARCH METHODOLOGY The review of existing and related works to source appropriate information on how to go about the implementation of the project will be carried out. Information shall be gathered from text books, magazines, journals, and World Wide Web to provide answers in relation to the study. Based on the review, the design and implementation of a four line private exchange box system shall be carried out. 1.6 LIMITATIONS OF STUDY There are several factors that could contribute to the group not delving deeper into this project which could have resulted in a more comprehensive work. Constraints are unavoidable in any system, be it a natural system or a computer system. Due to the extensiveness of this project topic, limitations were encountered some of which include: Time constraint. Financial constraints. Inadequate facilities to work with. 1.7 ORGANIZATION OF WORK In chapter one, the research topic is introduced, which is followed by the statement of problem after which the aims and objectives of the study are stated, significance of study, scope of study and research methodology are all identified. The second chapter gives us a view of the related works which have been done and how they are related to our work. The third chapter is about our design methodology and this emphasizes on how the whole private exchange system works and its components. The quality of the system is tested and documented in chapter four. Also in chapter four, an in-depth manual of the system functions and contents is given. A summary of all chapters, a conclusion is outlined in chapter five. CHAPTER TWO LITERATURE REVIEW 2.0 HISTORY OF PRIVATE EXCHANGE BOX In the field of telecommunications, a telephone exchange or telephone switch is a system of electronic components that connects telephone calls. A central office is the physical building used to house inside plant equipment including telephone switches, which make phone calls work in the sense of making connections and relaying the speech information. Early telephone exchanges are a suitable example of circuit switching; the subscriber would ask the operator to connect to another subscriber, whether on the same exchange or via an inter-exchange link and another operator. In any case, the end result was a physical electrical connection between the two subscribers telephones for the duration of the call. The copper wire used for the connection could not be used to carry other calls at the same time, even if the subscribers were in fact not talking and the line was silent. The first telephone exchange opened in New Haven, Connecticut in 1878. The switchboard was built from carriage bolts, handles from tea pot lids and bustle wire and could handle two simultaneous conversations. Later exchanges consisted of one to several hundred plug boards staffed by telephone operators. Each operator sat in front of a vertical panel containing banks of  ¼-inch tip-ring-sleeve (3-conductor) jacks, each of which was the local termination of a subscribers telephone line. In front of the jack panel lay a horizontal panel containing two rows of patch cords, each pair connected to a cord circuit. When a calling party lifted the receiver, a signal lamp near the jack would light. The operator would plug one of the cords (the answering cord) into the subscribers jack and switch her headset into the circuit to ask, number please? Depending upon the answer, the operator might plug the other cord of the pair (the ringing cord) into the called partys local jack and start the ri nging cycle, or plug into a trunk circuit to start what might be a long distance call handled by subsequent operators in another bank of boards or in another building miles away. 2.1 PBX SYSTEM COMPONENTS PBX is a telephone exchange serving a single organization and having no means for connecting to a public telephone system it serves a user company which wants to have its own communication branch to save some money on internal calls. This is done by having the exchanging or switching of circuits done locally, inside the company. There are some important components which play a major role in the implementation of an effective PBX system. Some of the Component The PBXs internal switching network. Central processor unit (CPU) or computer inside the system, including memory. Logic cards, switching and control cards, power cards and related devices that facilitate PBX operation. Stations or telephone sets, sometimes called lines. Outside Telco trunks that deliver signals to (and carry them from) the PBX. Console or switchboard allows the operator to control incoming calls. Uninterruptible Power Supply (UPS) consisting of sensors, power switches and batteries. Interconnecting wiring. Cabinets, closets, vaults and other housings. 2.2 PRIVATE BRANCH EXCHANGE (PBX) There are essentially three different types of PBXs that could be deployed within an organization infrastructure. It is necessary to be certain of type in use, so as to be able to identify the essential numbers. There are currently three different PBX classes: Centrex; Direct Inward Dialing (DID)/Direct Outward Dialing (DOD) and Megalink. 2.2.1 CENTREX Centrex is the easiest of the PBX types. This PBX, unlike other types is installed within the telephone companys Central Office (CO) and does not require dialing an extension code (normally 4 numeric characters) after having dialed the 7 to 10 digit number to connect a call to an individual. In a simplistic manner, it could be considered similar to the telephone used at home. It has an area code (NPA), an Exchange (NXX) and a Unique Number, (0000 to 9999) and does not require the dialling of another number after it in order to place a call. These numbers may be entered through a PAD. 2.2.2 Direct Inward Dialing(DID)/ Direct Outward Dialing (DOD) Unlike a Centrex, these types of PBXs is not installed within the telephone companys Central Office. Secondly, if a cut of the telephone wire occurs outside the building, individuals are still able to dial within it to talk to colleagues by simply dialing their extension number (normally a number between 0000 to 9999) lastly; this PBX is controlled via a computer interface at a control console. Since the PBX requires constant power to function, it may be necessary to hook it with generating plant, in the absence of power from electricity company. Direct Inward Dialing (DID) and Direct Outward Dialing (DOD) are simply features of an Automated PBX which require that you dial the companys general telephone number followed by the entry of the individuals extension number when prompted to do so. DIDs allow you direct dialing (seven digits) to locate an individual within an organizations PBX. It is a trunk phone number that must be entered into the PAD program and flagged as a PBX to ensure that the outgoing line(s) get priority. PBXs may be privately owned or telecommunication company owned. If PBX is programmable it is possible to assign specific trunk lines to specific numbers. These trunk line numbers may then be entered on PAD thus providing dial tone protection. 2.2.3 MEGALINKS The major difference between this and a Centrex PBX is that the exiting trunk lines from a building to the telephone company central office are comprised of fibre optic cables and not through twisted pair wiring. Another difference is that unlike a Centrex that is identified by its ten digit telephone number (NPA, NXX, and Unique), Megalinks are identified by a circuit ID number. This number may contain characters and may even resemble a telephone number, however, PAD does not allow for the entry of the circuit switch identifier. The reason is quite simple, fibre optic cabling circuits can handle far more traffic than twisted pair PBXs. 2.3 INTERFACE STANDARDS Interfaces for connecting extensions to a PBX include: POTS (Plain Old Telephone System) the common two-wire interface used in most homes. This is cheap and effective, and allows almost any standard phone to be used as an extension. Proprietary the manufacturer has defined a protocol. One can only connect the manufacturers sets to their PBX, but the benefit is more visible information displayed and/or specific function buttons. DECT a standard for connecting cordless phones. Internet Protocol For example, H.323 and SIP. Interfaces for connecting PBXs to each other include: Proprietary protocols if equipment from several manufacturers is on site, the use of a standard protocol is required. QSIG for connecting PBXs to each other, usually runs over T1 (T-carrier) or E1 (E-carrier) physical circuits. DPNSS for connecting PBXs to trunk lines. Standardised by British Telecom, this usually runs over E1 (E-carrier) physical circuits. Internet Protocol H.323, SIP and IAX protocols are IP based solutions which can handle voice and multimedia (e.g. video) calls. Interfaces for connecting PBXs to trunk lines include: Standard POTS (Plain Old Telephone System) lines the common two-wire interface used in most domestic homes. This is adequate only for smaller systems, and can suffer from not being able to detect incoming calls when trying to make an outbound call. ISDN the most common digital standard for fixed telephony devices. This can be supplied in either Basic (2 circuit capacity) or Primary (24 or 30 circuit capacity) versions. Most medium to large companies would use Primary ISDN circuits carried on T1 or E1 physical connections. RBS (Robbed bit signaling) delivers 24 digital circuits over a four-wire (T1) interface. Internet Protocol H.323, SIP, MGCP, and Inter-Asterisk eXchange protocols operate over IP and are supported by some network providers. Interfaces for collecting data from the PBX: Serial interface historically used to print every call record to a serial printer. Now an application connects via serial cable to this port. Network Port (Listen mode) where an external application connects to the TCP or UDP port. The PBX then starts streaming information down to the application. Network Port (Server mode) The PBX connects to another application or buffer. File The PBX generates a file containing the call records from the PBX. The call records from the PBX are called SMDR, CDR, or CIL.   (Micheal, 1999) 2.4 TELEPHONE Telephone is one of the most amazing devices ever created.   Although most people take it completely for granted, the telephone is one of the most amazing devices ever created. To talk to someone, just pick up the phone and dial a few digits; connection will be established with the person and a two-way conversation can take place. It is an instrument designed for simultaneous transmission and reception of the human voice. It works by converting the sound waves of the human voice to pulses of electrical current, transmitting the current, and then retranslating the current back to sound. The U.S. patent granted to Alexander Graham Bell in 1876 for developing a device to transmit speech sounds over electric wires is often called the most valuable ever issued. Within 20 years, the telephone acquired a form that has remained fundamentally unchanged for more than a century. The advent of the transistor (1947) led to lightweight, compact circuitry . Advances in electronics have allowed th e introduction of a number of smart features such as automatic redialing, caller identification, call waiting, and call forwarding. The figure 2.1 shows the major components that makes up a telephone set. 2.5 HOW TELEPHONE WORKS When a person speaks into a telephone, the sound waves created by his voice enter the mouthpiece. An electric current carries the sound to the telephone of the person he is talking to. A telephone has two main parts: (1) the transmitter and (2) the receiver.The Transmitter of a telephone serves as a sensitive electric ear. It lies behind the mouthpiece of the phone. Like the human ear, the transmitter has 14 eardrum. The eardrum of the telephone is a thin, round metal disk called a diaphragm. When a person talks into the telephone, the sound waves strike the diaphragm and make it vibrate. The diaphragm vibrates at various speeds, depending on the variations in air pressure caused by the varying tones of the speakers voice.   Behind the diaphragm lies a small cup filled with tiny grains of carbon. The diaphragm presses against these carbon grains. Low voltage electric current travels through the grains. This current comes from batteries at the telephone company. The pressure on the carbon grains varies as sound waves make the diaphragm vibrate. A loud sound causes the sound waves to push hard on the diaphragm. In turn, the diaphragm presses the grains tightly together. This action makes it easier for the electric current to travel through, and a large amount of electricity flows through the grains. When the sound is soft, the sound waves push lightly on the diaphragm. In turn, the diaphragm puts only a light pressure on the carbon grains. The grains are pressed together loosely. This makes it harder for the electric current to pass through them, and less current flows through the grains. Thus, the pattern of the sound waves determines the pressure on the diaphragm. This pressure, in turn, regulates the pressure on the carbon grains. The crowded or loose grains cause the electric current to become stronger or weaker. The current copies the pattern of the sound waves and travels over a telephone wire to the receiver of another telephone. The Receiver serves as an electric mouth. Like a human voice, it has vocal cords. The vocal cords of the receiver are a diaphragm. Two magnets located at the edge of the diaphragm cause it to vibrate. One of the magnets is a permanent magnet that constantly holds the diaphragm close to it. The other magnet is an electromagnet. It consists of a piece of iron with a coil of wire wound around it. When an electric current passes through the coil, the iron core becomes magnetized. The diaphragm is pulled toward the iron core and away from the permanent magnet. The pull of the electromagnet varies between strong and weak, depending on the variations in the current. Thus, the electromagnet controls the vibrations of the diaphragm in the receiver.The electric current passing through the electromagnet becomes stronger or weaker according to the loud or soft sounds. This action causes the diaphragm to vibrate according to the speakers speech pattern. As the diaphragm moves in and out, it pulls and pushes the air in front of it. The pressure on the air sets up sound waves that are the same as the ones sent into the transmitter. The sound waves strike the ear of the listener and he hears the words of the speaker.

It may be a bell, light, or warbling tone.  Ã‚   The ringing signal is in an AC wave form.   Although the common frequency used can be any frequency between 15 and 68 Hz.   Most of the world uses frequencies   between   20 and 40 Hz.  Ã‚   The voltage at the subscribers end depends upon loop length and number   of   ringers attached to the line; it could be between 40 and 150 Volts. The ringing cadence (the timing of ringing to pause), varies from company to company.   In the United States the cadence is normally 2 seconds of ringing to 4 seconds of pause. An unanswered phone in the United States will keep ringing until the caller hangs up.   But in some countries, the ringing will time out if the call is not answered. The   most   common   ringing   device is   the   gong   ringer; a solenoid   coil   with a clapper that strikes either a single or double bell. A gong ringer is the loudest signaling device that is solely phone-line powered. Modern telephones tend to use warbling ringers, which are usually ICs powered by the rectified ringing signal.   The audio transducer is a small   loudspeaker via a transformer. Ringers are isolated from the DC of the phone line by a capacitor. Gong ringers in the United States use a 0.47 uF capacitor.   Warbling ringers in the United States generally use a 1.0 uF capacitor.   Telephone companies in other   parts   of   the world   use   capacitors   between   0.2   and   2.0   uF.  Ã‚   The  Ã‚   paper capacitors of the past have been replaced almost exclusively with capacitors made of Mylar film.   Their voltage rating is always 50 Volts.   The capacitor and ringer coil, or Zeners in a warbling ringer, constitute a resonant circuit. When phone is hung up (on hook) the ringer is across the line; and it has merely silenced the transducer, not removed the circuit from the line. When the telephone company uses the ringer to test the line, it   sends   a   low-voltage, low frequency   signal   down   the   line (usually   2 Volts at 10 Hz) to test for continuity. The company compares result with the expected signals of the line.   This is how it can tell whether an added equipment is on the line. If your telephone has had its ringer disconnected, the telephone company cannot detect its presen ce on the line. Because there is only a certain amount of current available to   drive ringers, if ringers are added to phone lines indiscriminately, a point will be reached at which either all ringers will cease to ring, some will cease to ring, or some ringers will ring   weakly. A normal ringer is defined as   a   standard gong   ringer   as   supplied   in   a   phone   company   standard   desk telephone; Value given to this ringer   is   Ringer   Equivalence Number   (REN)   1. It can be as high as 3.2, which means that device consumes the equivalent   power   of   3.2 standard ringers, or 0.0, which means it consumes no current when subjected   to   a   ringing   signal.   If   there is a problem with ringing, it could be that the REN is greater than 5, disconnecting ringers until REN is at 5 or below will usually solve the problem. Other countries have various ways of expressing   REN,   and some   systems   will handle no more th an three of   their   standard ringers.   But whatever the system, if an extra equipment was added and the   phones   stop ringing, or the phone answering   machine   wont pick   up   calls,   the solution is disconnect   ringers   until   the problem   is resolved. Warbling ringers tend to draw less current than   gong   ringers, so changing from gong   ringers   to   warbling ringers may help spread the sound better. Frequency response is the second criterion by which a ringer is described. Because a ringer is supposed to respond to AC waveforms,   it will tend to respond to transients (such as switching transients) when the phone is hung up, or when the rotary dial is used on   an extension phone.   This is called bell tap in the United States; in other   countries,   its often called   bell   tinkle.  Ã‚   While European and   Asian phones tend to bell tap, or   tinkle,   United States ringers that bell tap are considered defective. The bell tap   is   designed out of gong ringers and fine   tuned   with   bias springs.  Ã‚   Warbling   ringers   for use in the   United   States   are designed   not   to respond to short transients;   this   is   usually accomplished   by   rectifying the AC and filtering   it   before   it powers the IC,   then not switching on the output stage unless the voltage lasts long enough to charge a second capacitor.(Roberts, 2006) 2.7 HOOK SWITCH This is a lever that is depressed when the handset is resting in its cradle. It is a two-wire to four-wire converter that provides conversion between the four-wire handset and the two-wire local loop. There are two stages, which are off   hook and on hook Off hook: The state of a telephone line that allows dialing and transmission but prohibits incoming calls from being answered. The phone is off-hook when the handset is removed from the base unit of a stationary phone or press Talk on a portable phone. The term stems from the days when the handset was lifted off an actual hook. When the handset was removed, a spring caused contacts to press together, closing the circuit from the telephone to the switchboard. On hook: The condition that exists when a telephone or other user instrument is not in use, i.e., when idle waiting for a call. Note: on-hook originally referred to the storage of an idle telephone reciever, i.e., separate earpiec, on a swithch hook. The weigth of the recieved depresses the sping leaded switch hook thereby disconnecting the idle instrument (except its bell) from the telephone line.  Ã‚  Ã‚  Ã‚   (Roberts, 2006) 2.8 THE DIAL There are two types of dials in use around the world. The most common one is called pulse, loop disconnect, or rotary; the oldest form of dialing, its been in use since the 1920s. The other dialing   method,   is called Touch-tone, Dual Tone Multi-Frequency   (DTMF) Pulse dialing   is traditionally accomplished with   a   rotary dial,   which is a speed governed wheel with a cam that opens   and closes a switch in series with the phone and the line.   It works by   actually   disconnecting   or hanging   up   the   telephone   at specific intervals.   The United States standard is one disconnect per  Ã‚   digit,  Ã‚   so if a   1, is dailled, the telephone   is disconnected once. To dial a seven means that it will be   disconnected seven times; and dialling a zero means that it will hang up ten times. Some countries invert the system so 1 causes ten disconnects   and 0,   one disconnect.   Some add a digit so that dialing a 5 would cause six disconnects and 0, eleven disconnects.   There are even some systems in which dialing 0 results in one   disconnect,   and all   other digits are plus one, making a 5 cause six   disconnects and 9, ten disconnects. Although most exchanges are quite happy with rates of 6   to 15   Pulses Per Second (PPS), the phone company accepted   standard is   8   to   10 PPS.   Some modern digital exchanges, free   of   the mechanical   inertia problems of older systems, will accept a   PPS rate as high as 20. Besides   the PPS rate, the dialing pulses have a   make/break ratio,   usually   described as a percentage, but   sometimes   as   a straight   ratio.   The North American standard is 60/40   percent; most of Europe accepts a standard of 63/37 percent.   This is the pulse measured at the telephone, not at the exchange, where   its somewhat   different, having traveled through the phone line   with its   distributed   resistance, capacitance,   and   inductance.  Ã‚   In practice, the   make/break   ratio does not   seem   to   affect   the performance of the dial when attached to a normal loop.   However,each pulse is a switch connect and disconnect across   a complex   impedance, so the switching transient often reaches   300 Volts. Usually, a safe practice is not to have fingers   across   the   line   when dialing. Most pulse dialing phones produced today use a CMOS IC and a keyboard.   Instead of pushing finger round in circles, then removing finger and waiting for the dial to return   before dialing the next digit, the button can be punched as fast as desired.   The IC stores the number and pulses out the number at the correct rate with the correct make/break ratio and the switching is done with a high-voltage switching transistor.   Because the IC has already stored the dialed number in order to pulse it out at the   correct rate,   its a simple matter for telephone designers to   keep   the memory alive   and allow the telephone to   store,   recall,   and redial the Last Number Dialed (LND).   This feature enables easy redial by picking up the handset and pushing just one button. Touch tone is the most modern form of dialing. It is   fast   and less   prone to error than pulse dialing.   Compared to pulse, its major advantage is that its audio band signals can   travel   down phone   lines further than pulse, which can travel only as far   as the   local   exchange. Touch-tone can therefore   send   signals around   the   world via the telephone lines, and can   be   used   to control phone answering machines and computers.   Bell   Labs developed DTMF in order to have a dialing   system that   could travel across microwave links and work   rapidly   with computer   controlled exchanges.   Each transmitted digit consists of two separate audio tones that are mixed together. The four   vertical columns on the keypad are known as   the   high group and the four horizontal rows as the low group; the digit   8 is   composed   of 1336 Hz and 852 Hz.   The level of each   tone   is within   3   dB   of the other.   A complete touch-tone pad has 16 digits, as opposed to ten on a pulse dial.   Besides the numerals 0 to 9, a DTMF   dial has *, #, A, B, C, and D.   Although the letters are not normally found   on consumer telephones, the IC in the phone is capable   of generating them. The   * sign is usually called star or asterisk.  Ã‚   The # sign,   often referred to as the pound sign. is actually   called an   octothorpe. Although many phone users have never used   these digits      they are not, after all, ordinarily   used in   dialing phone   numbers. They   are used   for   control   purposes,   phone answering machines, bringing up remote bases, electronic banking, and repeater control.   The one use of the octothorpe that may be familiar occurs in dialing international calls from phones.   After dialing the complete number,   dialing   the octothorpe   lets the exchange know youve finished   dialing.  Ã‚   It can now begin routing your call; without the octothorpe, it would wait and time out before switching your call. Standard DTMF dials will produce a tone as long as a key   is depressed.  Ã‚   No matter   how long you press,   the   tone   will   be decoded as the appropriate digit.   The shortest duration in which a digit can be sent and decoded is about 100 milliseconds   (ms).   Its pretty   difficult   to dial by hand at   such   a   speed,   but automatic dialers can do it.   A twelve-digit long distance number can be   dialed by an automatic dialer in a little   more   than   a second about as long as it takes a pulse dial to send a   single 0 digit.(Roberts,2006) 2.9 MODULAR CONNECTORS Modular connector is the name given to a family of electrical connectors that were originally used in telephone wiring. Even though they are still used for that purpose they are used for a variety of other things as well. A modular connectors advantage over many other kinds include; small size and ease of plugging and unplugging. Many uses that originally used a bulkier connector have migrated to modular connectors. Probably the most well known applications of modular connectors is for telephone jacks and for ethernet jacks, which are nearly always modular connectors. Figure 2.2 shows types of connectors commonly used. Modular connectors were first used in the registered jack system, so registered Jack specifications describe them precisely. These are the specifications to which all practical modular connectors are built. Modular connectors come in four sizes: 4-, 6-, 8-, and 10-position. A position is a place that can hold a conductor (pin). The positions need not all be used; a connector can have any even number of conductors. Unused positions are usually the outermost positions. The connectors are designed so that a plug can fit into any jack that has at least the number of positions as the plug. Where the jack has more positions than the plug, the outermost positions are unused. However, plugs from different manufacturers may not have this compatibility, and some manufacturers of eight position j

Oliver Cromwell as a Hero or Villain Essay examples -- History Ireland

The aim of this essay, is to answer the long-awaited question 'Was Oliver Cromwell a hero or a villain? This question, is a hard one to answer. James Heath once said "His name and memory stink." In opposition, Samuel Pepys said "People look back and praise him." True? Or Not? This essay will argue Edmond Ludlow's words," How glorious, but then such betrayal!" Oliver Cromwell was neither a hero nor a villain. The evidence and opinions gathered will state, how he went from good to bad, and from bad to evil. Oliver Cromwell, was a puritan gentleman from Huntingdon. He was born on the 25th of April 1599, and brought up in a very wealthy family, and a high social class. Cromwell, was an MP for Huntingdon, from 1628-1629. He had no fighting experience then, and was very worried about the Roundhead army, at the battle of Edgehill. Cromwell then went home to Huntingdon, and began to train his own army. Cromwell was a magnificent soldier. He created a whole new army from scratch, and he trained his army, in a special and unique way. Cromwell would do anything to win his battles, and beat Prince Rupert and if it meant making a whole new army, than so be it. To do this, he picked his people of their ability, 'men of spirit', and not on their status. He did this believing that this was right, as they were doing Gods will. It also made the people happy, and so he continued doing so. He also paid the men. He paid them 12D a day, so that encouraged more men to stay. He was a strict commander, and his orders had to be obeyed. Also, he always chose the right moment in a battle to attack. Some local Roundheads, thought that Cromwell should have ... ...er, but he just did what he felt he had to do. One thing which I agree on, is that he could have gone about it a different way. Also, I agree in one thing that he said, and also believed in. That was that "The end justifies the Means." What he meant by that, was that no matter what happens, something good always comes out at the end, and it's the end outcome that really matters. The words that I will leave you with, are the words of one Richard Baxter, a parliamentarian. We are not sure whether we can trust these words or not, as being a parliamentarian, he would have been a bit sympathetic to Cromwell, but it's quite reasonable. "No man was better and worse spoken of than he, he meant honestly, and was pious till power corrupted him, he thinketh that the end being good and necessary, the necessary means cannot be bad"

Mark Twain :: Free Essays

Just as Huckleberry Finn found peril along the waters of the great Mississippi River, contemporary students often find themselves treading their own 'deep waters' trying to understand and interpret the works of author Samuel Clemens, a.k.a. Mark Twain. But what Huck Finn never had, today's literature students do: the answer to any dilemma of interpretation...a website entitled Mark-Twain-Essays.Com. Tired of crawling through web pages with scant information and little to go on? THIS site contains not one.... not ten... but dozens upon dozens of essays reviewing, analyzing, & critiquing the works of Mark Twain! Whether you're reading The Adventures Of Tom Sawyer for the first time or performing a comparison and contrast between Pudd'nhead Head Wilson and Connecticut Yankee In King Arthur's' Court.Biography: Twain was born in Florida, Missouri in 1835, moving to the city of Hannibal (in the same state) when he was four. His formal schooling ended at the age of twelve, when he became apprenticed to a printer. His natural flair for words took him from printing into journalism, and his wanderlust took him from journalism into the life of a Mississippi riverboat pilot (Ousby 946). Reflecting his own life: Twain depicts much of his early life in the book Life on the Mississippi. As Albert Bigelow Paine writes, "In Life on the Mississippi we have [Twain’s] story of how he met Horace Bixby and decided to become a pilot instead of a South American adventurer -- jauntily setting himself the stupendous task of learning the twelve hundred miles of the Mississippi River between St. Louis and New Orleans -- of knowing it as exactly and as unfailingly, even in the dark, as one knows the way to his own features. It seems incredible to those who knew Mark Twain in his later years -- dreamy, unpractical, and indifferent to details -- that he could have acquired so vast a store of minute facts as were required by that task.

A Risk That Paid Off Essay

One of the biggest risks that paid off was my husband and I agreeing for him to join the Marine Corps. It required us to up and move our family from Utah to California with no friends or family around for support in times of hardship, which tends to come a lot with being a military family. I had to learn to take control of everything from paying the bills to taking care of the house and vehicles because of his training, field ops, and deployments which required him to be gone for weeks or months at a time. When he deploys I have to raise the kids on my own which is a challenge in itself. It creates chaos for the kids emotionally and they begin to act out at home and at school. They lose respect for both of us when he is gone. Having family time and alone time with each other becomes very limited because of his work schedule. We never know when our family time will be or even if there will be family time. With that being said you can only imagine how hard it is to get alone time together. I believe this all has and continues to pay off because I have created a whole new family within the Corps, I have made new friends that can never be replaced and only they can truly understand the struggles I go through better than any of my friends and family from home ever could. I have learned to be more self-reliant maintaining our household on my own. As far as our marriage it continues to get stronger with communication and we cherish each and every moment more than we ever have before as a family and as a couple.

Melodramatic stage Essay

â€Å"It isn’t so free here either, Rodolfo, like you think. I seen greenhorns sometimes get in trouble that way – they think just because girls do not go around with a shawl around her head that she isn’t strict, y’know?† Girls don’t have to wear black dresses to be strict. Know what I mean?†Ã‚  Although Eddie did not absolutely loose his temper he has forewarned Rodolfo very frankly in front of the whole of household that he should keep his distance from Catherine. â€Å"Well, I always have respect †Ã‚  Ã¢â‚¬Å"I know, but in your town you wouldn’t just drag off some girl without permission, you know what I mean Marco?†Ã‚  Marco who has been quiet until now cautiously says yes, he does not want to interfere between Rodolfo and Catherine but does not want to answer Eddie ‘no’ as this would make Eddie distrustful of him, which he wants to avoid.  Ã¢â‚¬Å"Well he didn’t just drag her off though, Eddie.†Ã‚  Beatrice on the other hand gets fractious by this and sharply replies to Eddie, Eddie aware of her criticising force softens up but doesn’t stop. He goes on to say –  Ã¢â‚¬Å"It might be a little different here, but it is just as strict.† Rodolfo now realises Eddie’s anger for him and in a tender-hearted voice asks him-  Ã¢â‚¬Å"Did I do anything wrong.†Ã‚  Eddie now propitiates and tells him that he is not her father, but before he could finish, Beatrice ungraciously interrupts and rebukes him to be her uncle. Eddie realising her indignation keeps his temper under control, as he wants to show Rodolfo who is the person in jurisdiction of the house  Marco who has been without intervention listening to the whole matter gets up in a censurable way and asks Beatrice and Eddie to tell Rodolfo, if he has made any mistakes. Marco probably does not fully actualizes Eddie’s anger against Rodolfo yet, he thinks it is ephemeral and tries to make things more transparent and satisfy Eddie. Beatrice tells Eddie that the reason why Rodolfo and Catherine came late was because the movie ended late, but Marco tries to calm Eddie by asking Rodolfo to come home early. Eddie sensing Marco on his side tries to restrict Rodolfo’s movements and stop him going out with Catherine by saying –  Ã¢â‚¬Å"Look, kid, I am not only talking about her. The more you run around like this more chance there is that you get picked by immigration bureau†.  Beatrice senses Eddie’s intentions and again ungraciously interrupts him between his conversations and says that there is the same chance in the daytime. Until now Eddie has been attempting to make his point Non contentiously, but after being ungraciously rebuked by Beatrice, he gracelessly tells cousins that he thought they were both coming here to work and earn money, not fool around. This exceptionally strikes with Marco as he has responsibility for feeding his wife and children. Marco confirms with Eddie, that this is still the case. This embarrasses Marco, because by saying that if you are here to work than you should work, Eddie is essentially saying you can only live in my house if, you work hard and particularly mind your own business. This is of exceptional significance to Marco as he has four children and a wife who he has to send money which provides for their food and medicine, or else they would die. This is also the first awkwardness between Marco and Eddie as until now Eddie has regarded Marco as a hard working man and always respected him. Catherine who is the focal point of this entire repercussion between cousins and Eddie is now glowing with revolt against him. Catherine who is a grown up girl, who wants to be free and spend more time with Rodolfo views Eddie as someone preventing her from outside world, indeed, Eddie is obsessed with Catherine and is extremely over-protective towards her. He wants to dominate every aspect of her life, from the clothes she wears to the person she waves to and where she should go for a job. And now Catherine flushed with anger tries to disobey Eddie by inviting Rodolfo to dance with her on ‘Paper Doll’. Rodolfo, who is afraid that Eddie may make an issue of this, shows some fictional unwillingness in difference to Eddie. Beatrice countenances Rodolfo to go ahead and dance. Catherine takes Rodolfo’s hand and he stiffly rises, feeling Eddie’s eyes on his back they dance. The tension between the characters can be easily seen in their actions. Catherine’s rebellious behaviour is easily visible, when she goes to Rodolfo and takes his hand in her hand and invites him to dance. Rodolfo doesn’t easily agrees to dance, he first shows fictional unwillingness feeling Eddie’s eyes on his back, but after being inspired by Beatrice stiffly rises and goes to dance.  Eddie perceiving the tension in the house does not react to Catherine dancing with Rodolfo, but turns his head away in a very deprecate demeanour. At this point in the play, audience know that Eddie Carbone is very prophylactic towards his niece and he despises Rodolfo. This new crisis has taken a categorically different turn; Catherine is becoming more and more mutinous and Beatrice is advocating Rodolfo and Catherine. Eddie seems to be the only person secluded trying to what he thinks, protect Catherine from Rodolfo. Audience anticipate this extremity to be deciphered possibly by Beatrice. Throughout the whole play Beatrice has been impersonated by Miller as the most consequential person on Eddie Carbone, she has also actively tried to diffuse the tensions by jokes and in some contentions she has taken sides and silenced Eddie. She is also the person who is most consequential and proximate to Eddie. However, Carbone household is once again under strain, as Eddie Carbone the prophylactic, unpretentious character soon finds out that he is  Un-proficient to control his indignation, covetousness and detestation towards Rodolfo. Until now, Eddie has only been manifesting his indignation towards Rodolfo through declamation, but this melodramatically changes after Catherine, crimsoned with rebellion, disgusted with Eddie’s intervention in every countenance of her life invites Rodolfo to dance with her. This brings out an exorbitant indignation from Eddie, now we see Eddie expressing his vehemence not only through words but also through actions. After the dance, Eddie Carbone infuriated by his indignation delivers an atrocious dialogue to the whole of the household about Rodolfo.  Ã¢â‚¬Å"He’s lucky, believe me. That’s why the waterfront is no place for him. I mean like me – I can’t cook, I can’t sing, I can’t make dresses, so I’m on the waterfront. But if I could cook, if I could sing, if I could make dresses, I wouldn’t be on the water front.†Ã‚  This speech is of un-describable significance to the play. In this speech Eddie nearly exposes the whole issue in front of the whole household, by his dialogue but more by his actions. Eddie, by the end of his speech is perfunctorily twisting the newspaper in his hand in to a tight roll when it unexpectedly tears in half. This shows exasperated and how fretful Eddie has become of Rodolfo’s relationship with Catherine, and now Eddie’s indignation has reached a new level against Rodolfo and now his furore a nd ire can be seen in his actions. As seen throughout the whole play Miller uses melodramatic stage directions and often characters dramatize actions which changes the course of the whole play. For example, Eddie’s furore and ire against Rodolfo are disclosed, when Eddie rolls the newspaper in to a tight roll and then it tears in two. These types of actions not only give audiences clues of how this particular character will react to this character and to this kind of situation next time, but also gives them clues of what will happen next in the play.

Hagar Currie Shipley from the novel “The Stone Angel” by Margaret Laurence and Edgar Gallant Essay

Through the character Hagar Currie Shipley from the novel â€Å"The Stone Angel† by Margaret Laurence and Edgar Gallant, we can see that life experience and religion have certain affects on people which may change as they grow older. Those impacts can be for the good or the bad. These decisions are made by the people who experience something so great that had changed their minds. When someone goes thought something that might have changed their lives then they sometimes become a different person. Hagar Shipley is often found in contact with her past but not with her emotions. She had been thought a lot in her life and one thing was holding her back which lead her to make the decisions she did. On the other hand, Edgar Gallant, uses his emotions to share his past with his relatives and loved ones. Being this way Edgar became the person he is now. These two people are unique in their own ways but they still have certain similarities with their lives experiences. First Paragraph Hagar Shipley’s life experience has an important affect on her present self since she keeps on leaving the present whenever she feels uncomfortable. In her old age, she escapes the present through daydreaming and wanders around in her past in search of a situation where she had control instead of having to deal with the present situation. For example when Hagar is given Barium by the doctor at the hospital and she is wondering what will happen next: â€Å"I’ve waited like this, for things to get better of worse, many and many a time. I should be used to it. So many years I waited at the Shipley’s place†¦Ã¢â‚¬  We see here that Hagar does not feel comfortable in the present being given a substance she does not know. Therefore Hagar leaves the present in search of a situation she has been in previously where she knows what will happen. Hagar does not only escape from the present mentally but also physically. Even though Hagar is a very proud woman, she becom es progressively more powerless to care for herself and therefore becomes an unbearable tension on her son, Marvin and his wife, Doris. This tension becomes even worst as she takes a trip away from home leaving them stranded, not knowing where she has disappeared: â€Å"Oh dear, you threw an awful scare into us. Why should you go and do such a thing, anyway, mother? When I came back from the store, and found you weren’t there, I nearly when out of my mind. Its been so worrying for us, and we felt so awful, having to go to the police. They looked at me in such a funny way, as though I should’ve taken better care, but how on earth was I to know you’d do a thing like that?† We see here the problems that Hagar has inflicted upon her son and his wife. We do not hear very often of an old lady of ninety two years old running away from home. Hagar needs care because she has become a child. Hagar was never a child because her father made her grow up faster then her age. So as Hagar looks into her past at her childhood she sees a grown up child, so in her old age, she became the child she never was. Hagar’s college education was not a very important part of Hagar’s life even though it has prevented her to live the care free of a young growing women. In those days, college was not the same for girls and boys. We can see this through a quote from Jason Currie: â€Å"It’s not the same for you-there’s no women here to teach you haw to behave like a lady.† Jason was sending Hagar East to learn how to become a lady, not for work related knowledge. This is shown by Jason when Hagar come home two years later: â€Å"Do you think I sent you down East for two solid years just so you could take a one-room school?† Hagar’s father did not need her to learn to do any type of work, he had sent her there for her to be pretty and know how to behave herself like a lady to show off to the entire town to show off his daughter. â€Å"You’re a credit to me. Everyone will be saying that by tomorrow. You’ll not work in the store. It wouldn’t do.† We here realizes that Jason has sent his daughter Hagar to college so that he could be proud of her. Hagar is also very proud as we can see when her father hits her: â€Å"I wouldn’t let him see me cry. I was so enraged.† This is pride, she has inherited from her father. Her father then realizes that she will not let him see her cry and says: â€Å"You take after me, you’ve got backbone, I’ll give you that.† From this quote, we can see that Hagar’s pride comes directly from her father. Hagar once said:† â€Å"Pride was my wilderness and the demon that led me there was fear.† She has been afraid of being unrespectable which is why she decided to go to college and was easily convinced that it was she that should go and not Matt. Afraid of needing too much and giving too much, Hagarâ€℠¢s pride is both unsettling and inspirational. Second Paragraph Edgar Gallant’s life experience and past memories have an important effect on his life and relationships with others. Edgar had a very interesting past that affects him even today. His past affects his career as a volunteer in the later years of his life as he helps out others with his knowledge. He has been asked to take part in over a dozen organizations due to his previous success in his life’s work. Not thinking he has fulfilled his dream and what he was sent here to do, he has accepted to help out in about nine different association for the public usually as a president or vice president of comities. Edgar Gallant uses his past, not to hide, but to enrich his every day’s work. Unlike Hagar, Edgar has usually worked in a team thinking that several brains are better then one, sharing information to reach a better solution that one could not come up with alone. Edgar does not hide his emotions, he believes that hiding a certain part of them is good in the work environment because of the professional look and rational approach to have in a work environment with work partners. On the other hand, he is very open towards his family and shares everything with them. He has shared hi time between work and family always leaving enough time to carry on his duties as a responsible father. Sharing his feeling with his wife and children, he was able to create a feeling of trust and educate his children in the way he thought was best. Edgar found that sharing some degree of emotion show as well as the rational view of things was the best approach in family situation. It is good to show emotion to a certain degree. One does not want to overwhelm, but share his problems with his family. â€Å"I have always consciously made an effort not to let emotion dominate reason.† This shows that he shares his emotions with others but does not let them take over by keeping a rational look on things. Edgar was never really proud in the same way as Hagar. He was often given position he though were above his expertise, but decided that since others had that trust in him, that he would not deceive them so he went on to do what was expected of him, never letting anyone down. Third Paragraph Hagar’s take on religion has changed throughout her life. In her younger age, Hagar was very religious and went to church with her father. Then she found out that her father was having an affair with Lotions mother and since then she started being less religious. After John’s death Hagar stopped being completely religious. She prayed for him to live, but to no avail as she explained to Mr. Troy. She feels that praying is useless because god will not respond to her in the end. Edgar’s take on religion has also changed with age. When he was a boy, his family was very religious. At the age of 13, he was sent to a boarding school which had a priests where all his companions and teacher were extremely religious. As soon as he left the boarding school, he then realized that he did not agree with some of the religious concepts he was taught. From then on he decided to take a different look on religion. As he got old he leaned more about the world and that added to his concepts to religion which was also a reason why it changed. Just like Hagar, Edgar does not currently practice a certain religion but has beliefs of his own inspired from the Catholic Church and books. Edgar has changed his view on religion due to philosophical books, religious texts from other religions and his work which is about social justice and truth to the people. Due to his knowledge as he grew older, he has come to realize that not one religion is true, but that all of them have something good and that religious belief is a sum of all of them. He also mentioned that there is not way of knowing which religion is the right one so taking bits from all of them can maybe create a better understanding from all of them. He also did not let religion take over his life which enabled him to work more frequently. From her childhood as a daughter of a Scottish merchant to her marriage, Hagar has fought a long and wrong battle for freedom and respect. In the end she realises her wrong doings when it became too late, she has gone with her life without thinking about her actions and the consequences. When someone does not know if they are at fault they keep repeating those actions until its too late to reverse them. Edgar on the other hand has nothing to look back on, he knew exactly what he wanted and went right for it. In Edgar’s case he was raised by and worked hard to earn respect which in the end he was granted respect by others. The work he has done for the society is incredible and he is still doing so in a manner that will benefit the society and him self. He will not stop working until he probably can’t function anymore. The benefit that he is getting out of it is the joy of being able to make a difference. Hagar unfortunately realized this near the end of her life, when time was running out. She realized this when she only performed one task to help out the girl in the hospital. If only she realised that helping others is rewarding and makes a difference, then she could have started at an earlier age. Whether it’s a person’s character or religion, as one grows older their views change. This could include a change in heart or opinion.
