Time slot switching for integrated services in fiber optic PBX/LAN

Abstract

Operational principles of the TSS protocol are explained. A performance analysis is presented to show the tradeoffs among traffic capacity, frame guard time, blocking probability, and transmission delay. The analysis is done for 64 Kbit/s channels, and the results show that TSS is more attractive than broadcast protocols for voice traffic or constant-rate data traffic. An approach to integrating voice, data, and video traffic within TSS is also described.
