ABSTRACT:
The interface card consists of a circuit pack containing the line or trunk circuitry and a face plate connected to one side of the circuit pack. A first connector is located on the side of the circuit pack opposite the face plate for connecting the line card to the backplane of the switching system or other network element. A second connector is provided on the face plate for connecting the circuit pack to the cable plug of the cabling. To disconnect the connector, an ejection mechanism is provided on the face plate of the interface card. The ejection mechanism slides relative to the face plate to force camming surfaces into engagement with abutment surfaces on the cable plug thereby forcing the cable plug perpendicularly away from the face plate. Thus the plug is removed without damaging the pin connectors. A locking device can be optionally provided on the ejection mechanism to lock the cable plug into engagement with the pin connector to prevent inadvertent disconnection.
