Abstract
A method for bypassing the common control and switch matrix of a class 5 digital switch, comprising providing a means to convert the signals and protocols used with the line/trunk frames associated with the class 5 digital switch to those used by the remote end of a DLC; providing network interfaces for one or more digital transmission facilities that make up the remote end of a DLC; and providing a means to couple the line/trunk frames with the switching system interface. A switching system interface comprising one or more network interfaces for terminating digital transmission facilities; one or more interfaces for coupling to line/trunk frames of a digital switch; a time-slot assignment means for connecting time slots of the digital transmission facilities to those of the line/trunk frames; and a call processing means for coordinating call setup and teardown between the DLC local terminal and the line/trunk frames, and for managing the time-slot assignment means to complete calls.
