Abstract

An integrated office controller (IOC) network includes, in combination, a plurality of station devices each capable of transmitting and receiving multiplexed bearer and signal channel information; user port interface means for carrying said multiplexed information between a station device and a station multiplex/demultiplex device (SMX); a plurality of SMXs, each associated with and coupled to a predefined cluster of said station devices, via said user port interface means, for concentrating the multiplexed information froms said interface means into channel signals, central equipment module (CEM) means, including a call processor, a non-blocking switch matrix and clock means, for switching channel signals through said switch matrix under the control of said cell processor and clock means; transmission system means, capable of interfacing SMXs and trunk cards to said CEM, where said transmission system means includes modular line interface module (LIM) means for interfacing a plurality of SMXs and the CEM, and modular trunk interface module (TIM) means for interfacing trunks with the CEM; and host processing means, coupled to the CEM, for providing support for standard IOC features and programmable applications. The IOC functions as a digital pulse code modulated (PCM) information handling system for voice, and simultaneous handling of data signal communication between stations serviced by IOC SMX's.
