Abstract:
A network for telephony and high frequency communication comprising:(1) a plurality of electrically-conductive segments each containing at least two distinct electrical conductors operative for conducting a low-frequency telephony band and at least one high-frequency band, each of said segments having a respective first end and a respective second end; (2) a first low pass filter coupled in series to the respective first end of a selected one of said said segments, for establishing a low-frequency path for said low-frequency telephony band; (3) a second low pass filter coupled in series to the respective second end of said selected one of said segments, for establishing a low-frequency path for said low-frequency telephony band; (4) a first high pass filter coupled in series to the respective first end of said selected one of said segments, for establishing a high-frequency path for said at least one high-frequency band; (5) a second high pass filter coupled in series to the respective second end of said selected one of said segments, for establishing a high-frequency path for said at least one high-frequency band; and (6) means operative for coupling at least one telephone device to at least one of said low-frequency paths, and for coupling at least one high frequency device to at least one of said high-frequency paths; â€ƒwherein: said two distinct electrical conductors at said first end of said selected one of said segments are coupled only to said first low pass filter and said first high pass filter and said two distinct electrical conductors at said second end of said selected one of said segments are coupled only to said second low pass filter and said second high pass filter.
