A channel capable of transmission in only one direction, which cannot be reversed. Synonym unidirectional channel.
Industry:Telecommunications
A channel capable of transmitting all the information required for communication, such as user data, synchronizing sequences, and control signals. Note: The information-bearer channel may operate at a higher data rate than that required for user data alone. 2. A basic communications channel with the necessary bandwidth but without enhanced or value-added services.
Industry:Telecommunications
A channel derived by dividing an allocated or available bandwidth over a medium into two or more portions, each usable separately. Note: A frequency-derived channel is continuously available and may be further divided on either a frequency or time basis.
Industry:Telecommunications
A channel in which the send and receive circuits have the same data signaling rate.
Industry:Telecommunications
A channel mapping designation that ranges between 1 and 216 and relates the digital circuit multiplication equipment (DCME) transmission trunk to an internal numbering designation used within the DCME for conveying trunk-channel-to-bearer-channel connectivity via the DCME assignment channel.
Industry:Telecommunications
A channel provided on telecommunications facilities to support administration and maintenance. For primary rate access, the EOC is the extended superframe (ESF) data link.
Industry:Telecommunications
A channel with a bandwidth narrower than that of a voice-grade channel. Note: A subvoice-grade channel is usually a subchannel of a voice-grade line.
Industry:Telecommunications
A character added to a transmission block to facilitate error detection. Note: In longitudinal redundancy checking and cyclic redundancy checking, block check characters are computed for, and added to, each message block transmitted. This block check character is compared with a second block check character computed by the receiver to determine whether the transmission is error free.
Industry:Telecommunications
A character set established in accordance with unambiguous rules that define the character set and the one-to-one relationships between the characters of the set and their coded representations.
