RLSD is ON in idle, RLSD tracks in online. The RLSD circuit is normally ON in the Idle State, and it is ON while the remote carrier is present in the online state. In the online state, RLSD goes OFF immediately after loss of carrier. If carrier goes on and stays on for the time set by S9, then RLSD will go ON again.

If the hangup process begins while RLSD is OFF, then RLSD will go ON just prior to the issue of the "NO CARRIER"result code.
