■DCS

If a telephone in a DCS network is involved in a malicious call, the

extension is recorded and displayed with the MCT information. MCT

notification passes over ISDN-PRI DCS trunks but MCT-Activate,

within the same DCS node.

■Emergency Access to the Attendant

Recorder port to drop the connection.
