US 6,807,273 B2 · Method and apparatus for bypassing the common control and switch matrix of a digital switching system for telecommunications networks

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.

Dependent claims

A method for bypassing the common control and switch matrix of a first class five digital switching system for telecommunications networks, said method comprising the steps of:

accessing internal signals of said first class five digital switching system used to control line and trunk interfaces of said first class five digital switching system and convey data in and out of said line and trunk interfaces;
providing a switching system interface comprising at least one network interface connected to at least one digital transmission facility that is part of a network architecture, and comprising interfaces compatible with said internal signals;
and
connecting said compatible interfaces of said switching system interface to said internal signals of said first class five digital switching system the connection between said compatible interfaces and said internal signals enabling a terminal in said network architecture to directly operate said internal signals to provide telecommunications service to subscribers connected to said line and trunk interfaces without the use of said common-control-and switch matrix of said first class five digital switching system.
