• In this entry —
• “affiliated equipment” means the following equipment: input/output (I/O) control units; recording or reproducing equipment; displays; or other peripheral equipment;
• “common channel signalling” means a signalling method in which a single channel between exchanges conveys, by means of labelled messages, signalling information relating to a multiplicity of circuits or calls and other information such as that used for network management;
• “communication channel” means the transmission path or circuit including the terminating transmission and receiving equipment (modems) for transferring digital information between distant locations;
• “data device” means equipment capable of transmitting or receiving sequences of digital information;
• “data (message) switching” means a technique, including store-and-forward or packet switching, for: accepting data groups (including messages, packets or other digital or telegraphic information groups which are transmitted as a composite whole); storing (buffering) data groups as necessary; processing part or all of the data groups, as necessary, for the purpose of: (1) control (routing, priority, formatting, code conversion, error control, retransmission or journaling); (2) transmission; or (3) multiplexing; and (d) retransmitting processed data groups when transmission or receiving facilities are available;
• “data-signalling rate” means the maximum rate in either transmission or reception, taking into account that, for non-binary modulation, baud and bit per second are not equal; (binary digits for coding, checking, and synchronization functions are included);
• “digital computer” means equipment which can, in the form of one or more discrete variables: accept data; store data or instructions in fixed or alterable storage devices; process data by means of a stored sequence of instructions which is modifiable; and provide output of data;
• “fast select” means a facility applicable to virtual calls, which allows data terminal equipment to expand the possibility of transmitting data in call set-up and clearing packets beyond the basic capabilities of a virtual call;
• “local area network” means a data communication system which: allows any number of independent data devices to communicate directly with each other; and is confined to a geographical area of moderate size (such as an office building, a plant, a campus, or a warehouse);
• “PABX” (private automatic branch exchange) means an automatic telephone exchange (whether or not incorporating a position for an attendant), designed to provide access to the public network and serving extensions within an institution;

• “packet-mode operation” means the transmission of data by means of addressed packets, whereby a transmission channel is occupied for the duration of the packet only and the channel is then available for use by packets being transferred between different data terminal equipments; (in certain data communication networks the data may be formatted into a packet or divided and then formatted into a number of packets, either by the data terminal equipment or by equipment within the network, for transmission and multiplexing purposes);
• “space-division analogue exchange” means a space-division exchange, which uses an analogue (including sampled analogue) signal within the switching matrix, and which can route digital signals, subject to the bandwidth limitations of the equipment; (such exchanges in public networks commonly pass digital data rates of several kilobit per second per voice channel of 3,100 Hz);

• for the purpose of this definition a combination of such equipment (such as a combination of printer and paper tape punch or reader)which is connected to a single data channel or communications channel, constitutes a single terminal device;
• “terminal exchange” means an exchange which performs the function of one or more of the following— a local exchange used for terminating subscribers' lines; a remote switching unit which performs some functions of a local exchange and operates under a measure of control from the parent exchange; or a local exchange which is used as a switching point for traffic between subordinate local exchanges (and which is generally 2-wire but may also provide 4-wire connections to and from the national long-distance network);
• “time-division analogue exchange” means a time-division exchange in which the parameter associated with an individual segment of a stream of data or voice signals varies continuously;

• “total data signalling rate” means the sum of the individual data signalling rates of all communication channels which have been provided with the system and can be sustained simultaneously, assuming a configuration of equipment that would maximize this sum of rates;
• “transit exchange” means an exchange that performs the function of a terminal exchange or one or both of the following: a switching point for traffic between other exchanges in the national network (otherwise known as a “trunk exchange” and generally 4-wire); or a 4-wire exchange serving outgoing, incoming or transit international calls;
• “trunk circuit” means a circuit with associated equipment terminating in two exchanges. Any term used in this entry shall bear the same meaning it has in entry IL1565 and entry IL1566 in this Group.
