Telephone communication system over a single telephone line
First Claim
1. A device for coupling a telephone device to at least one time-domain multiplexed digitized voice channel carried over bus topology wiring in a building, the wiring having at least two conductors, the device comprising:
- a local area network modem couplable to the wiring and operative to communicate with at least one other modem over the bus topology wiring in the building;
selective means coupled to said local area network modem and operative to pass a first voice channel;
a subscriber line interface coupled to said selective means and operative to convert said first voice channel to a first analog telephone signal; and
a first telephone connector coupled to said subscriber line interface and couplable to a telephone device to couple the telephone device to said first analog telephone signal.

12. A device for coupling at least one analog telephone service signal to at least one time-domain multiplexed digitized voice channel carried over a wiring having at least two conductors, for use with an analog telephone service connection for conducting the analog telephone service signal and connectable to an analog telephone set, the device comprising:
-
at least one exchange line interface connectable to the at least one analog telephone service connection, and operative to convert the at least one analog telephone service signal to a digitized service signal; and a modem coupled to said at least one exchange line interface and operative to conduct said digitized service signal over the wiring. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
