A network interface device for connecting telephone company lines and subscriber lines comprising an enclosure with a base and a cover and a socket having at least two sets of three switchable contacts, the first and second contacts (telco and customer) of each set being of a heavier gauge material than the third contact (test) of each set to improve reliability, the socket providing a point of demarcation between the telephone company and subscriber lines. Use of operational plugs (FIGS. 44, 47, 50) and dummy plugs (FIGS. 46, 49) is disclosed.

Network interface device with switchable contacts

A plug-actuated switchable electrical socket having at least one set of three electrical contacts, two of the three contacts being of a heavier wire gauge than the third contact, the insertion of a plug in the socket effecting a switching action between at least two of the three contacts.

Switchable electrical socket

A wire termination device for terminating insulated wires using insulation displacement contacts. The device may employ a pivotally mounted lever with a curved slot for receiving a pin or may employ a pivotally mounted rocker arm, movement of the lever and rocker arm effecting termination of the insulated wire by forcing the wire into engagement with the insulation displacement contact.

Wire termination device

A modular device for connecting telephone company wiring and subscriber telephone wiring in a telephone network interface apparatus, the modular device having a replaceable protection and/or electronics unit, a plug-actuated switchable socket or a switch connected to an external socket for providing a point of demarcation between the telephone company wiring and the subscriber wiring, wire termination mechanisms for terminating and unterminating the telco and subscriber wiring at the network interface apparatus without the use of tools and slidable security covers.
