  • Parallel control of a telephone switching network
    Patent number: 3997736
    Abstract: A switching system is disclosed for interconnecting both the audio and wideband communication leads of communicating telephone stations. The system utilizes an auxiliary switching network separate from the regular audio network for handling the wideband portion of each interconnection. The connections through the auxiliary network are identified for control purposes by tracer signals applied to a called line and detected on the calling line. The tracer signals are applied and detected without interfering with the regular switching network and without major modifications to the existing network.
