In telecommunication, the Aeronautical Emergency Communications System Plan (AECS) provides for the operation of aeronautical communications stations, on a voluntary, organized basis, to provide the President and the Federal Government, as well as heads of state and local governments, or their designated representatives, and the aeronautical industry with an expeditious means of communications during an emergency. ...more on Wikipedia about "Aeronautical Emergency Communications System Plan"
Alarm indication signal (AIS) is a signal transmitted by a system that is part of a concatenated telecommunications system to let the receiver know that some remote part of the end-to-end link has failed at a logical or physical level, even if the system it is directly connected to is still working. Other systems attached to a system transmitting AIS then relay the AIS indication onwards to other systems. ...more on Wikipedia about "Alarm indication signal"
Alternate party diversion is an optional feature of telephone services, where a call may be routed to a different number based on time-out and precedence schemes set up by the customer. ...more on Wikipedia about "Alternate party"
In electronics, analog decoding is the portion of the digital-to-analog conversion process that generates an analog signal value from the digital signal that resulted from analog encoding. ...more on Wikipedia about "Analog decoding"
In telecommunication, associative storage is a computer storage device whose storage locations are identified by their contents, or by a part of their contents, rather than by their names or positions. Associative storage can also refer to this process as well as to the device. This is also known as content-addressable storage. ...more on Wikipedia about "Associative storage"
In telecommunications, asynchronous operation or asynchronous working is where a sequence of operations is executed such that the operations are executed out of time coincidence with any event. It can also be an operation that occurs without a regular or predictable time relationship to a specified event; e.g., the calling of an error diagnostic routine that may receive control at any time during the execution of a computer program. ...more on Wikipedia about "Asynchronous operation"
The asynchronous start-stop is the more common of two basic modes of teletypewriter operation, allowing a common means of encoding characters over a serial link such as a telegraph circuit or an RS-232 interface. Asynchronous start-stop uses a "start bit" followed by some number of data bits, possibly a "parity" bit, and one or two "stop bits". ...more on Wikipedia about "Asynchronous start-stop"
In telecommunication, an audio response unit (ARU) is a device that provides synthesized voice responses to touch-tone keypresses ( DTMF) by processing calls based on (a) the call-originator input, (b) information received from a host data base, and (c) information in the incoming call, such as the time of day. ...more on Wikipedia about "Audio response unit"
In telecommunication, the term audit has the following meanings: ...more on Wikipedia about "Audit (telecommunication)"
An audit trail is a record of transactions or communications all related to a single person, account or other entity. Webopedia defines it as "a record showing who has accessed a computer system and what operations he or she has performed during a given period of time." ( ** ) ...more on Wikipedia about "Audit trail"
In telecommunications, the term automated information system is an assembly of computer hardware, software, firmware, or any combination of these, configured to accomplish specific information-handling operations, such as communication, computation, dissemination, processing, and storage of information. Included are computers, word processing systems, networks, or other electronic information handling systems, and associated equipment. ...more on Wikipedia about "Automated information system"
In telecommunication, the term automated information systems security is absolutely useless. The unauthorized disclosure, modification, or destruction may be accidental or intentional. ...more on Wikipedia about "Automated information systems security"
Automatic Frequency Control (AFC) is a method (or device) to automatically maintain a tuning of electromagnetic radiation (radio or microwave) signal to desired frequency. ...more on Wikipedia about "Automatic frequency control"

In telecommunication, automatic sounding is the testing of selected channels or paths by providing a very brief beacon-like identifying broadcast that may be used by other stations to evaluate connectivity, propagation, and availability, and to identify known working channels for possible later use for communications or calling. ...more on Wikipedia about "Automatic sounding"
In data communications, an automatic switching system is a switching system in which all the operations required to execute the three phases of information- transfer transactions are automatically executed in response to signals from a user end-instrument. ...more on Wikipedia about "Automatic switching system"
In voice, video, or data communications, the term available line (or useful line) is a circuit between two points that is ready for service, but is in the idle state. In facsimile transmission, the portion of the scanning line that can be specifically used for image signals. ...more on Wikipedia about "Available line"
A back-channel in an broadband asymmetric telecommunications system is typically a low-speed or less-than-optimal transmission channel opposite to the main channel's direction. See channel (communications). ...more on Wikipedia about "Back-channel"
In telecommunications, a back-to-back connection is a direct connection between either: ...more on Wikipedia about "Back-to-back connection"
In a data circuit a backward channel is the channel that passes data in a direction opposite to that of its associated forward channel. The backward channel is usually used for transmission of request, supervisory, acknowledgement, or error-control signals. The direction of flow of these signals is opposite to that in which user information is being transferred. The backward-channel bandwidth is usually less than that of the primary channel, that is, the forward ( user information) channel. For example, ADSL's upstream channel, considered a backward channel for some types of analysis, typically has a bandwidth less than one-fourth of the downstream channel. ...more on Wikipedia about "Backward channel"
In telecommunications, a balanced line is a transmission line consisting of two conductors in the presence of ground, capable of being operated in such a way that when the voltages of the two conductors at all transverse planes are equal in magnitude and opposite in polarity with respect to ground, the currents in the two conductors are equal in magnitude and opposite in direction. ...more on Wikipedia about "Balanced line"
In telecommunication, the term bandwidth compression has the following meanings: ...more on Wikipedia about "Bandwidth compression"
Base communications (basecom): Communications services, such as the installation, operation, maintenance, augmentation, modification, and rehabilitation of communications networks, systems, facilities, and equipment, including off-post extensions, provided for the operation of a military post, camp, installation, station, or activity. Synonym communications base station. ...more on Wikipedia about "Base communications"
All signals are comprised of a whole range of different frequencies added up together. In telecommunications in particular, it is often the case that those parts of the signal which are at low frequencies are 'copied' up to higher frequencies for transmission purposes, since there are few communications media that will pass low frequencies without distortion. Then, the original, low frequency components, are referred to as the baseband signal. Typically, the new, high frequency copy is referred to as the 'RF' ( radio frequency) signal, although it need not be at the particular frequencies set aside for radio. ...more on Wikipedia about "Baseband"
