Attorney, Agent or FirmInternational ClassH04M 009/00Foreign Application Priority Data1996-10-25 CAAbstractA 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.Field of SearchHAVING NEAR FIELD LINK (E.G., CAPACITIVE, INDUCTIVE)Noise, distortion, or singing reduction Interface attached device (e.g., interface with modem, facsimile, computer, etc.) Smart cable Including private cordless extension system Including public cordless extension system ONE-WAY AUDIO SIGNAL PROGRAM DISTRIBUTION Having push-pull-engaging contacts spaced along planar side wall transverse to longitudinal engagement axis (e.g., telephone jack or plug) Direct grounding of coupling part member passing into aperture CROSSTALK SUPPRESSION | |
