clear channel A DS-0 channel of 64 kbps, all of which can be used for user payload, network manage- ment, or other applications, as the requisite signaling and control functions for the circuit are accomplished out-of-band. As the signaling and control functions are performed in separate channels or even in a separate network designed specifically for that purpose, there is no bit robbing or otherwise intrusive technique that consumes channel capacity intended for payload. As examples, E-carrier and ISDN support clear channel communications. See also bit robbing, E-carrier, DS-0, ISDN, out-of-band signaling and control, and payload. |
