Multi-network architecture

Integrated management of multiple networks with different topologies

A communication system for implementing remote operations between a PABX and a host computer, conforming to Open Systems Interconnect (OSI) communication protocol. Circuitry is provided in each of the PABX and host computer for generating and encoding invoke, return result, error and reject operation protocol data unit signals, for transmission between application layer entities of the PABX and host computer. In order to support invoking of asynchronous telephony operations, invoke address and server address fields are incorporated within the argument sequence and the result sequence of the invoke and return result operation protocol data unit signals, respectively.
