Abstract

A minimum size bus for interconnecting different modules of an ISDN PBX is presented in this paper. The distributed system used has many peripheral modules running the link layer protocols and four central modules dealing with B-channel switching, signalling messages and D-channel packet data transfer. The proposed architecture takes advantage of asymmetries in module communication and permits fair access and good performance in using the single bus.
