Abstract

Describes a signalling interface between an International Switching Centre (ISC) and a Digital Circuit Multiplication Equipment (DCME) that has the additional (compared to ITU-T Q.50) capability to control the compression/decompression function of the DCME. This signalling interface provides for the call by call control of a DCME in real time.
