An apparatus for controlling data traffic throughout a communication network includes a plurality of network interface devices in each subsystem. The interface devices are substantially identical throughout the network and each autonomously controls all data traffic thereacross.

Data subsystem traffic control apparatus and method

A system for providing data services in an evolutionary fashion as well as providing access to external data communication networks for subscribers to a circuit switched voice exchange includes a data services adjunct connected in series with presently existing voice communication paths.

System for providing data services to a circuit switched exchange

A data transport control apparatus including a storage medium independently accessible by a device interface controller for interconnecting the storage medium and peripherals, a communication bus control for interconnecting the storage medium and a communication bus and a microprocessor bus for interconnecting the storage medium and a microcomputer wherein all interconnections to the storage medium are effectively isolated from each other.

Data transport control apparatus

A full service voice/data system includes a networking medium having a plurality of substantially identical subsystems interconnected thereto. Each subsystem includes a local voice information path and a local data information path, the local data information path including a masterless multiple access contention bus with collision detection.

Full service voice/data system

An apparatus for efficiently executing communication protocol conversions includes a plurality of peripheral interface devices each executing only a single communication protocol conversion whereby the processing capacity required is reduced for each such device. In addition, a single network wide uniform communication protocol is incorporated within each apparatus.

Apparatus and method for executing communication protocol conversions

A communication subsystem includes a plurality of peripheral interface devices, one or more network interface devices and, optionally, one or more gateway interface devices. Each and every interface device includes a uniform data transport controller that autonomously controls data traffic across the device associated therewith and executes all requisite communication protocol conversions.
