553-3001-306 Standard 10.00 January 2002
The CTI Trunk Monitoring and Control feature introduces the concept of
Associated trunks (AST). Previously, only Associated sets existed. An
Associated trunk is configured by setting the AST prompt to YES in the
Trunk Data Block. When AST = YES, the trunk can be monitored and
controlled from a host CTI application via the AML interface. AST includes
both Associated sets and Associated trunks. The number of AST sets and
trunks that can be configured on one system is subject to Incremental
Software Management (ISM) limitation.
The CTI Trunk Monitoring and Control feature includes the following four
functionalities:
• Trunk Monitoring
• Trunk Call Disconnect
• Warning Tone
• Route Member Information Element (IE)
Trunk Monitoring
With the Trunk Monitoring functionality, Unsolicited Status Messages
(USM) are generated to report the Associated trunk status to the CTI
application via the AML interface. The status of the Associated trunk is
reported when the trunk is answered at the far-end and when the trunk is
disconnected at the far-end.
Trunk Call Disconnect
With the Trunk Call Disconnect functionality, the Call Disconnect Request
(CALLDIS) message is enhanced to disconnect a trunk call. Trunk Call
Disconnect allows the CTI application to disconnect a trunk call given either
the Disconnect Party TN (in packed format) or the route and member number
of the trunk. In order for the trunk call to be disconnected, all of the following
conditions must be met:
• Either the Disconnect Party TN or the trunk route and member number
must be valid.
• The trunk must belong to the Customer group, as indicated by the
Customer number in the CALLDIS message.
