A metallic access test extension system architecture for a digital transmission system is provided. The digital transmission system includes a local end and a plurality of remote ends, each of said plurality of remote ends including a digital communication path and a metallic test pair connection. The local end includes a corresponding digital communication path and corresponding metallic pair connection. The architecture includes a remote unit coupled to each metallic test pair and digital communication path at each of said plurality of remote ends. The remote unit includes a metallic access test extension module. The architecture further includes a central office unit at the local end of the digital communication path, the local end unit including a metallic test extension module and a switch system, responsive to a control signal, for selectively connecting the digital communication paths and metallic test pairs at the local and to the metallic test extension module in the local end unit. In a second embodiment, the test system includes a POTS test system, a special services test system, a metallic test extension local end unit module and a metallic test extension remote unit module. Each remote unit is coupled to a metallic bypass pair line at the remote and to which the digital transmission system may connect any of a plurality of metallic pairs connecting to customers.

Metallic access test extension system architecture

A system for accessing a plurality of telephone wires which are two-wire, four-wire and six-wire circuits, including a common access test bus, a common control bus, a plurality of access shelves for connecting the circuits to the common access test bus, in which each access shelf is individually selectively controllable to connect the circuits to the common access test bus in response to control signals on the common control bus, and a test controller having a programmable data processor for selectively generating the control signals to individually control any one of the access shelves. The relay switch of the system for closing and splitting twelve wires includes a first relay having twelve contacts, corresponding to the twelve wires, respectively, for closing the twelve wires and for splitting the twelve wires into twenty-four wires, a second relay, having twelve contacts, for closing a first twelve of the twenty-four wires, each of two of these twelve contacts being on two of the first twelve wires, respectively, and a third relay, having twelve contacts, for closing a second twelve of the twenty-four wires, each of two of these twelve contacts being on two of the second twelve wires, respectively.
