Abstract

The present invention provides a Digital PB
exchanger with a Multi-processor control system by using an ATM for a plurality of Digital PB exchangers with a single processor control system to multiplex PCM
voice data and communication data between processors.
The Digital PB exchanger consists of a Processor unit, a Time division switch, a subscriber circuit, a trunk circuit, a telephone terminal and the like. A PCM
voice signal and data from the Time division switch 21 are connected to the ATM switch 5 via the ATM interface circuit 31 so that communication of the audio signal can be made possible. Furthermore, when data is transmitted from one processor to another processor, the data from the processor is multiplexed with the audio signal by the ATM interface circuit and is transmitted to other ATM interface circuits.
