The 25 pair color code is a color code used to identify individual conductors in a kind of electrical communication wiring known as twisted pair cables. The colors are applied to the insulation that covers each conductor. The first color is chosen from one group of five colors and the other from a second group of five colors, giving 25 combinations of two colors. ...more on Wikipedia about "25-pair color code"
2600 Hz is the frequency in hertz (cycles per second) that AT&T formerly put as a steady signal on any long-distance telephone line that was not currently in use. Prior to widespread use of out-of-band signaling, AT&T used in-band signaling, meaning that signals about telephone connections were transmitted on the same line as the voice conversations. Since no signal at all on a line could indicate a pause in a voice conversation, some other way was needed for the phone company to know when a line was free for use. So AT&T put a steady 2600 hertz signal on all free lines. Knowing this, certain people developed a way to use a whistle or other device (i.e. Blue-Boxes) to generate a 2600 hertz tone on a line that was already in use, making it possible to call anywhere in the world on the line without anyone being charged. Once the operator mode was established using these techniques, it would then become a simple matter of presenting valid DTMF audio signals to dial the desired actual phone number. Cracking the phone system became a hobby for some in the mostly under-20 set who came to be known as phone phreakers. ...more on Wikipedia about "2600 hertz"
4B3T stands for 4 (four) Binary 3 (three) Ternary. It's a line encoding scheme used for ISDN BRI interface. It represents four binary bits using three pulses. It uses three states viz. + (positive pulse), no pulse - 0, - (negative pulse). To avoid DC buildup on the physical medium it uses suitable combinations of positive and negative pulses to represent a nibble. This mapping from 4 bits to 3 ternary states is given in a table known as Modified Monitoring State 43 (MMS43). ...more on Wikipedia about "4B3T"

AIOD leads are Terminal equipment leads used solely to transmit automatic identified outward dialing (AIOD) data from a PBX to the public switched telephone network or to switched service networks (e.g., EPSCS), so that a vendor can provide a detailed monthly bill identifying long-distance usage by individual PBX stations, tie trunks, or the attendant. ...more on Wikipedia about "AIOD leads"
Airfone is a brand of air-ground radiotelephone service offered by Verizon. Airfone allows passengers to make telephone calls in-flight. It was orginated by John D. Goeken (who also founded MCI and FTD) in the 1970s and sold to GTE in 1986 and Western Union. Delta offered the nation's first public air-to-ground telephone system with Airfone. An Airfone telephone is usually located in the seatback of the seat in front of the passenger, there may only be one per row in coach class, while first class may have one per seat. Airfone phone calls are usually quite expensive compared to ground-based telephone calls, however, they are often discounted or free for customers of airplane-based catalogs like Sky Mall. More recently the Airfone service has been used for data connections as well, and is working towards wireless broadband on airplanes. ...more on Wikipedia about "Airfone"
Alberta Termination Test Lines are a rare type of test line that was used during the Telus area code split in Alberta (403 to 780 for North, 403 for South). The numbers will terminate at a recording, allowing one to leave a message, and were used to test call routing in the new area code and to keep line technicians in communication. ...more on Wikipedia about "Alberta Termination Test Line"

Average Margin per User (AMPU) provides a criterion for measuring the success of telephone operators. It is an alternative to ARPU, which focus narrowly on revenue per unit. The central idea is that if you're focusing on how much margin you produce per sold unit, not the amount of cash ( revenue) you earn from each customer, you can afford low volumes and still have a healty company. If you get high volumes you will have an significant edge until competition forces prices down. Telecom analysts are traditionally highly focused on ARPU, which isn't too strange when you consider that the typical telco has had huge infrastructure costs that needs to be serviced by a considerable ARPU. ...more on Wikipedia about "AMPU"
Analog Display Services Interface is a telephony technology that is currently used in POTS or computer-based PBX telephone service. It works in conjuction with a screen-based telephone ("screenphone") or other compatible CPE to provide the user with softkey access to telephone company or internal PBX custom calling features. It is an analog service because it uses analog Frequency Shift Keying ( FSK) technolgy to interact with an LCD screen via short, low-baud rate, downloads to refresh and re-program softkeys in real-time. ...more on Wikipedia about "Analog Display Services Interface"
An answering machine, also known as an answer machine (especially in UK and British commonwealth countries), ansafone ( tradename ** ), ansaphone (tradename ** ), answerphone or telephone answering device (TAD), is a device for automatically answering telephone calls and recording messages left by callers when the party called is unable to answer the phone. Unlike voicemail, which is a centralised or networked system that performs a similar function, an answering machine is installed in the customer's premises alongside the customer's telephone. While early answering machines used magnetic tape technology, most modern equipment uses solid state memories. Magnetic tape is still used in many low cost devices. However, answering machines that use magnetic tape cannot be found in most stores today. ...more on Wikipedia about "Answering machine"

Asterisk is an open source software implementation of a telephone private branch exchange (PBX). Like any PBX, it allows a number of attached telephones to make calls to one another, and to connect to other telephone services including the PSTN. "Its name comes from the asterisk symbol, *, which in Unix (including Linux) and DOS environments represents a wildcard, matching any filename." ** ...more on Wikipedia about "Asterisk PBX"

An autodialer alarm, or community alarm as it is known in Britain when it is run by the County council, is an electrical device that usually has a push button transmitter which an individual may use to summon assistance to their location. These portable transmitters send a signal to the alarm unit. The transmitter is designed to be worn around the neck, on your wrist or clipped onto your clothing. Some brands offer additional methods of setting off the alarm such as a push button on the alarm unit itself, wall buttons or pull cords. Some alarms will go off automatically if they detect smoke, an intruder, a low room temperature or if the individual hasn't moved in a while. ...more on Wikipedia about "Autodialer alarm"
An automated attendant system allows the caller to be automatically be transferred to a user's extension without the intervention of a receptionist. A receptionist can be reached by pressing 0 on most systems. There is a dial-by-name directory like 411 to find user on a system. The dial-by-name directory is usually set up last name followed by first name. Once the user ID is announced you can press # or it will automatically ring the extension. Express messaging is used when you don't want to disturb the user or are calling a guest mailbox without a phone. ...more on Wikipedia about "Automated attendant"

In telecommunication, an automatic callback is a service feature that permits a user, when encountering a busy condition, to instruct the system to retain the called and calling numbers and to establish the call when there is an available line. Automatic callback may be implemented in the terminal, in the switching system, or shared between them. Automatic callback is not the same as camp-on. ...more on Wikipedia about "Automatic callback"
