A method of and system for monitoring the conditions of channels in a multichannel telecommunications line, wherein each of the traffic channels uses A/B bit signaling to signal their condition. Whenever the system detects a setup acknowledgment message in a command channel that includes a call reference and a channel identifier, the system displays the detected setup acknowledgment message and monitors the channel identified by said channel identifier for a change in line status, as indicated by a change in its A/B bits. In response to detection of a change in the A/B bits of the channel identified by the channel identifier, the system decodes the A/B bits and displays the changed line status. |
