G 127
[Subsidiary]
(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"-
The rate as defined in ITU Recommendation 53-36, 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.
NB:
It is the maximum one-way rate, i.e., the maximum rate in either transmission or reception.
"digital computer"----
Equipment which can, in the form of one or more discrete variables:
(a) Accept data;
(b) Store data or instructions in fixed or alterable (writable) storage devices;
(c) Process data by means of a stored sequence of instructions which is
modifiable; and
(d) Provide output of data.
NB:
Modifications of a stored sequence of instructions include replacement of fixed storage devices, but not a physical change in wiring or interconnections.
"embedded" in equipment or systems-
Can feasibly be neither
(a) Removed from such equipment or systems; nor
(b) Used for other purposes.
"local area network”-
A data communication system which:
(a) Allows an arbitrary number of independent "data devices" to communicate
directly with each other; and
(b) Is confined to a geographical area of moderate size (e.g. office building, plant,
campus, Warehouse).
"PABX"
See "private automatic branch exchange". "private automatic branch exchange”-
An automatic telephone exchange, typically incorporating a position for an attendant, designed to provide access to the public network and serving extensions in an institution such as a business, government, public-service or similar organization.
"software"-
A collection of one or more "programmes" or "microprogrammes" fixed in any tangible medium of expression.
"space-division analogue exchange”-
A "space-division exchange", using an analogue (including sampled analogue) signal within the switching matrix. Such exchanges can route digital signals, subject to the bandwidth limitations of the equipment. Thus, such exchanges in public networks commonly pass digital data at rates of several kilobit per second per voice channel of 3 100 Hz as defined in CCITT Recommendation G. 151.
N.B.
A "space-division analogue exchange" with a wideband switching matrix can be converted to a "space-division digital exchange" by modifying some or all of the input interface circuitry.
