Abstract: A software-based telecommunications switch architecture with distributed supervision, network communications, and signal processing provides an expandable call volume handling capacity without having to add additional supervisory processing capability. The call signals are processed by a plurality of media control platforms which communicate with a supervisory network services processor and communicate with the network through a packet manager. The switch can be expanded by adding more media control platforms without the need to provide a new or additional network services processor or packet manager.

Abstract: A method of call processing includes passing, over a local area network, control signals from a centralized controller to each of a plurality of decentralized processors. The method also includes having each of the plurality of decentralized processors, in response to the control signals, executing decentralized call control functions.

Abstract: A method provides reserved bandwidth in a system having dual unidirectional and oppositely oriented buses. The method is intended to enhance the proposed standard, DQDB Metropolitan Area Network. A portion of the bandwidth shared by the stations in accordance with the proposed standard is reserved for distribution to stations on an as required basis. Each station making a request for bandwidth is allocated a part of the reserved bandwidth. Empty isochronous cells are used to provide the reserved bandwidth on the buses.

Abstract: A method provides effective priority access in a system having dual unidirectional and oppositely oriented buses. The method is intended to enhance the proposed standard, DQDB Metropolitan Area Network. An effectiveness factor K is introduced to enhance the effectiveness of the priority. In one embodiment lower priority CD counters are incremented by K for each higher priority request. A second embodiment also increments lower priority RQ counters. A third embodiment increments the lower priority CD slots only for the highest request received in a given slot. A fourth embodiment also increments lower priority RQ counters. A variation provides a threshold counter for controlling the use of the effectiveness factor.
