Claims18
For a building which contains wiring coupled to an external network, a communication system comprising:
- a voice channel on the wiring coupled to exchange signals with the external network;
- and
- a data channel on the wiring configured to pass signals within the building, the data channel being different from the voice channel and isolated from the external network,
- wherein at least one wire of the wiring supports the voice channel and the data channel simultaneously.
1 more element
A communication system for a building comprising:
- a first wire pair having a first voice channel and a first data channel different from the voice channel, the first voice channel and first data channel supported simultaneously on the wire pair;
- a second wire pair having a second data channel;
- a third wire pair having a second voice channel;
- and
- a jack electrically coupled to the first wire pair, the second wire pair, and the third wire pair,
- wherein the jack electrically 1) couples the first data channel to the second data channel, 2) couples the first voice channel to the second voice channel, and 3) isolates the first voice channel and second voice channel from the first data channel.
3 more elements
A device comprising:
- a first port configured to accept a first wire pair supporting both a data channel and a voice channel simultaneously;
- a second port configured to accept a second wire pair supporting the voice channel;
- and
- a third port configured to accept a third wire pair supporting the data channel and suppressing the voice channel, and
- a circuit, wherein the circuit electrically 1) couples the first port and the second port to carry the voice channel, 2) couples the first port and third port to carry the data channel, and 3) isolates the voice channel in the first port from the data channel in the third port.
