    • 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.
    • 本发明提供一种具有多处理器控制系统的数字PB交换机,其通过使用具有单个处理器控制系统的多个数字PB交换机的ATM来复用PCM语音数据和处理器之间的通信数据。 数字PB交换机由处理器单元,时分交换机,用户电路,中继电路,电话终端等构成。 来自时分开关21的PCM语音信号和数据经由ATM接口电路31连接到ATM交换机5,使得音频信号的通信成为可能。 此外,当数据从一个处理器发送到另一个处理器时,来自处理器的数据由ATM接口电路与音频信号多路复用,并被发送到其他ATM接口电路。
