A communication system including a collection of modules coupled in a ring architecture which integrates synchronous and asynchronous message transmission. Asynchronous data packets and synchronous voice packets are exchange on a single communication link. Packetized information exchange references a fixed length window with all synchronous data being exchanged at the beginning of each window and with asynchronous data exchanged during the remaining portion of each window. Virtual circuits utilizing the synchronous packets can deliver telephone conversations without degradation in voice quality and yet the system can also transmit asynchronous data packets. |
