Abstract:
A method of implementing a local area network in a home telephone network having a connector, configured for sending and receiving ISDN-based signals to and from a public switched telephone network, and a four-wire bus including a two-wire send path and a two-wire receive path for sending and receiving the ISDN-based signals, respectively, between the connector and connected ISDN terminal devices, the method comprising:connecting a low pass filter between the two wires of the two-wire send path at an output terminal of the connector, the low pass filter configured for passing the ISDN-based signals and rejecting harmonics thereof and isolating capacitive influences of the connector from the two-wire send path; isolating capacitive influences of each of the connected ISDN terminal devices from the two-wire send path; and transmitting by a network node a first home network signal onto the two-wire send path and a second home network signal, complementary to the first home network signal, onto the two-wire receive path.
