Patent ID: 6927336

Claim:
A modular interworking interface module for telecommunication switching systems, which comprises: a mounting frame, with an indicator lamp mounted on a top portion of a front panel; a monitor terminal port, a pair of interworking terminal I/O ports and a pair of tracking terminal I/O ports arranged in tandem below the indicator lamp; and a pair of system terminal I/O ports mounted on a back panel; wherein the interworking terminal, tracking terminal and system terminal each has a pair of corresponding I/O ports; an output connection module with a conductive metal coating or metal plating on the internal surface, and multiple half-round notches for placing tubular pipes containing conductive wires, which allow for system connection and automatic exchange of line connection between a pair of output ports from the system terminal to either the tracking terminal or interworking terminal; an input connection module with a conductive coating or metal plating on the internal surface, and multiple half-round notches for placing tubular pipes containing conductive wires, which allow for system connection and automatic exchange of line connection between a pair of input ports from the system terminal to either the interworking terminal or tracking terminal.
