Telephone communication system over a single telephone line
First Claim
1. A network for coupling each of a first bi-directional serial digital data stream and a second bi-directional serial digital data stream external to a building to respective ones of first and second units in the building, said network comprising:
- first wiring comprising two conductors at least in part in walls of the building and at least in part external to the building, said first wiring being connected to carry the first and second bi-directional serial digital data streams in time multiplexed form;
second wiring comprising two conductors at least in part in walls of the building, said second wiring being connected to carry the second bi-directional serial digital data stream;
a first outlet connected to said first wiring, said first outlet being mounted in a wall opening or an outlet opening;
a second outlet connected to said second wiring, said second outlet being mounted in a wall opening or an outlet opening;
a first device couplable to the first unit, said first device being connected to said first outlet for connection to said first wiring and being connected to said second wiring, said first device being operative to couple the first bi-directional serial digital data stream to the first unit and to pass the second bi-directional serial digital data stream between said first and second wirings; and
a second device couplable to the second unit, said second device being connected to said second outlet for connection to said second wiring, said second device being operative to couple the second bi-directional serial digital data stream to the second unit.
