Description: This attribute specifies duration of the 'await response' supervisory timer which applies to non call-associated sessions providing bearer-independent connection-oriented transport for supplementary services. The timer is started at the ingress Passport when creation of a virtual circuit with the egress Passport is confirmed and stopped when the first message from the destination PBX is received. If the timer expires, the non call-associated session is cleared. The 'await connection' timer (attribute connectServiceTimer) together with 'await response' timer (attribute responseServiceTimer) provide equivalent of the T-ACTIVATE timer described in the relevant supplementary service specifications. A change of the timer value does not apply to timers already running.
