A characteristic of a sequence or group of messages that allows several messages to be sent by one party to the same message recipient without waiting for a response to each message.
Industry:Telecommunications
A characteristic of a transmission path in which the bit position allocated for customer data may represent any combination of zeros and ones. For the DS1 rate, the bits allocated for customer data are the last 192 bits of each frame.
Industry:Telecommunications
A characteristic of an image (e.g., a photograph) such that the image has all the values (0 to 100%) of gray (black and white) or color in it. Note: A continuous tone can be approximated by the use of thousands or millions of gradations of black and white or colors. The granularity of computer screens (viz. , pixel size) can limit the ability to display absolute continuous tone.
Industry:Telecommunications
A characteristic of design and installation, expressed as the probability that an item will be retained in or restored to a specified condition within a given period of time, when the maintenance is performed in accordance with prescribed procedures and resources. 2. The ease with which maintenance of a functional unit can be performed in accordance with prescribed requirements.
Industry:Telecommunications
A characteristic of some digital data transmission systems that impose no restrictions on, or modification of, the transmitted bit sequence. Note: Bit-sequence-independent protocols are in contrast to protocols that reserve certain bit sequences for special meanings, such as the flag sequence, 01111110, for HDLC, SDLC, and ADCCP protocols.
Industry:Telecommunications
A characterization of a simple standardized combination of access channels that constitute the access arrangements for the majority of ISDN users; specifically, any of the following combinations of access channels: (1) one D-channel, (2) one B-channel plus one D-channel, (3) two B-channels plus one D-channel.
Industry:Telecommunications
A character-oriented, data-link-layer protocol. Note: The bi-sync protocol is being phased out of most computer communication networks in favor of bit-oriented protocols such as SDLC, HDLC, and ADCCP.
Industry:Telecommunications
A check made across the exchange to verify that an acceptable speech path exists.
Industry:Telecommunications
A check made of a circuit to verify that a communication or power path exists.
Industry:Telecommunications
A check to determine the integrity of transmission of data, whereby the received data are returned to the source for comparison with the originally transmitted data. Synonym loop check.
