Coupling together two or more communication systems that use different signaling protocols requires a protocol converter. A protocol converter is provided that includes interfaces to communications systems to be coupled together mimics the operation of the communications systems each interface is coupled to providing a seamless coupling between the systems.

Methods and apparatus for translating between telephone signaling protocols

In the disclosed system, the operation of a target computer is monitored by a terminal controller connected to one or more of the computer's input/output ports. The controller can send data on one of the computer's ports and simultaneously record and monitor computer response at several of the computer's input/output ports. Two data queues are provided for each monitored port and received data is stored in a first queue, referred to as a spooler queue, and may be searched for a specified character string before it is transferred to the second queue called the demux queue. Received information, in addition to being searched for a specified character string, is also examined for message type and a message type designation is added to each data word or message transferred to the demux queue. From the demux queue the data is transferred to different storage files depending upon the message type designation. The transfer of data through the queues is controlled by several processes which communicate via a shared memory area. Such a set of queues and processes is provided for each monitored port, operating independently from processes for other ports.
