DATA CAPTURE ARRANGEMENT FOR A CONFERENCE CIRCUIT

摘要

DATA CAPTURE ARRANGEMENT FOR A CONFERENCE CIRCUIT A time shared conference circuit for establishing conference calls in a T-S-T digital switching network provides for trapping certain PCM voice data from the output PCM voice data stream of the conference circuit. Data is automatically trapped for detection of errors such as parity. Data in any specific time slot may be trapped for a non-error condition under control of a processor.
