Abstract

An out-of-band signaling mechanism for a T-1 multipath digital time division multiplex telecommunication system transports signaling information exclusive of in-band, robbed bit signaling. The out-of-band signaling mechanism reserves a portion of the available bandwidth of a DS0 channel for exclusive transport of signaling information as an out-of-band DS0 signaling channel, and employs the remaining portion of the available bandwidth of that same DS0 channel as a sub-rate data communication DS0 channel.
