ITU-T Q.20-1988 宽带综合业务数字网(B-ISDN)概述 信令能力集1、版本1

Signalling over telephone circuits may be effected in the frequency band used for speech ("in-band" signalling), or outside it ("out-band" signalling). In the latter case, the same channel carries both the signalling and speech frequency bands, the signalling band being separate from the speech band, and signalling equipment is an integral part of the carrier system.

Comparative advantages of "in-band" and "out-band" systems

ITU-T M.300-1988 TMN建议综述

Those of the following definitions that concern links or sections apply,unless otherwise stated,to the combination of both directions of transmission.A distinction between the two directions of transmission may,however,be necessary in the case of unidirectional, multiple-destination links or sections set up over multiple-destination communication satellite systems.
