VOCABULARY OF SWITCHING AND SIGNALLING TERMS
(Geneva, 1980; modified at Malaga-Torremolinos, 1984; Melbourne
1988)
1 This Recommendation provides a vocabulary of terms and definitions which have been studied for application in documentation on switching and signalling. The possible evolution toward integrated digital networks and integrated services digital networks has been taken into account.
2 The terms are grouped in sections and within each section terms belonging to the same area of concepts are assembled. While such grouping in logical order may ease overview, it was not established according to firm principles and arbitrary placing of certain terms was accepted.
3 Part of the terms and definitions in this Recommendation also are contained in specialized glossaries which are attached to certain Recommendations of the G, Q and Z Series. Care has been taken then that identical texts appear in both the Recommendation and the glossary.

Annex A -- Alphabetical list of terms defined in this Recommendation.
According to the conventions applied in the lists, indications in round brackets are qualifiers or alternative terms in general use in addition to the principal term.
|
Examples: call (in software) Examples: exchange (switching exchange, switching centre) Terms in square brackets are deprecated. The indication (USA) | after a term in English means that the term is used in the United States, and is different |
from that current in the United Kingdom. The indication (UK) | means the reverse.
A number (1) or (2) after a term indicates that more than one definition is given (when the term acquires another meaning depending on the context).
Cross-references to the sources in §§ 1 to 9 are given, where of interest, at the right-hand side of the line following the end of a definition.
Sources quoted are ISO, Recommendation G.701 [1] and Recommendation I.112 [7], List of Essential Telecommunication Terms [2], the International Electrotechnical Vocabulary (IEV), Recommendations E.100 and E.600 [3]. The name of ISO and Recommendations are mentioned along with a number; the terms derived from the ``List of Essential Telecommunications Terms'' give only a four digit number. The four digit number from E Recommendations [3] is preceded by the designation ``Study Group II''. Numbers beginning with 714 refer to Chapter 714 (Switching), those with 716 to Chapter 716 (ISDN) of IEV.
General terms and definitions as shown in § 0 have in many cases not been elaborated by Study Group XI. However, they need to be used in certain definitions for which the Study Group is responsible. A cross-reference to the source is given wherever possible. If no cross-reference is given, the term is quoted with the provisional meaning that Study Group XI adopted for it. Such definitions will be substituted by the definition of the competent body when available. It should be noted that the terms concerned will not necessarily be classified by the responsible body as ``general'' in the sense applied to § 0.

4 Fascicle VI.1 -- Rec. Q.9
S: canal de acceso [canal]
A designated part of the information transfer capability, having specified characteristics, provided at the user-network interface.
Note 1 -- The term ``transmission channel'' is well understood to imply uni-directional working only, and then is commonly abbreviated to ``channel''. To avoid confusion with this usage, the term ``access channel'', which encompasses bi-directional working through the user-network interface, must not be abbreviated to ``channel''.
Note 2 -- The term ``access channel'' may be qualified, for example, by H, B, or D in which case it is appropriate to abbreviate the term to ``H-channel'', ``B-channel'' or ``D-channel''.
