out-of-band signaling


out-of-band signaling: 1. Signaling that uses a portion of the channel bandwidth provided by the transmission medium, e.g. , the carrier channel, which portion is above the highest frequency used by, and is denied to, the speech or intelligence path by filters. Note: Out-of-band signaling results in a lowered high-frequency cutoff of the effective available bandwidth. 2. Signaling via a different channel (either FDM or TDM) from that used for the primary information transfer. (188) Contrast with common-channel signaling, in-band signaling, out-slot signaling.
