A dual unit diagnostic system for testing the physical status of a multi-pair cable. Each unit comprises connectors which are connectable to the cable wire pairs, and switches that are connected to the connectors, and are also activatable to provide distinguishable conductive pathways between each wire pair. A signal transmission section is connected to the switches, and provides a signal to a selected wires. A signal reception section is also connected to the switches for receiving a signal from distinguishable wires. A microprocessor is connected to the transmission section and the detection section, and which controls the transmission and reception of signals. A display is connected to the microprocessor and switches, and provides information to distinguish various physical wire status conditions based on the reception of the signal at predetermined wires.

DETAILED DESCRIPTION The present invention provides a diagnostic system for testing the physical status of a multi-pair cable, for example, telecommunications cable.
The system comprises a pair of test units or devices each having connection means which are adapted to be connected to the cable wire pairs, and switch means that are connected to the connection means, and are also activatable to provide distinguishable conductive pathways between each wire pair.
Transmission means are connected to the switch means, and provide a signal to a selected wire pair.
Detection means are also connected to the switch means, and are for receiving a signal from a distinguishable wire among the cable wire pairs.
A microprocessor is connected with the transmission means and the detection means which controls the transmission and reception of the signal to and from predetermined wires.
Indicating means are connected to the microprocessor and the switch means, and provide information to distinguish various physical wire status conditions based on the reception of the signal at predetermined wires.
These and other benefits of this invention will become clear from the following description by reference to the drawings.
