ABSTRACT:
A fixed wireless access subscriber unit extension telephone cable connecting arrangement is disclosed. The cable itself includes a single pair of wires for carrying the tip and ring signals between the subscriber unit and an extension telephone set. The cable also includes at least one additional wire, or pair of wires. This additional wire or pair of wires is connected to an effective ground, thus reducing the noise signal induced in the cable which is passed to the extension telephone set. This effective ground can be a node within the fixed wireless access subscriber unit which serves as the electrical common for the unit. In this case it is preferable to connect the additional wire, or pair of wires to the effective ground via a suitable capacitor or capacitors.
