Abstract
A network for coupling at least one telephone service signal to at least one telephone device over a wiring. The network includes: a wiring having at least two conductors for carrying multiple time-domain multiplexed digitized voice channels; an exchange side device coupled to the wiring and operative to couple at least one telephone service signal to at least one digitized voice channel; and at least one subscriber side device coupled to the wiring and operative to couple the at least one telephone device to at least one digitized voice channel.

A network in a building for coupling at least one telephone service signal to at least one telephone device in the building, the network comprises:
- a wiring having at least two conductors for carrying multiple time-domain multiplexed digitized voice channels;
- an exchange side device in the building coupled to said wiring and operative to couple at least one telephone service signal to at least one digitized voice channel;
- and
- at least one subscriber side device in the building coupled to said wiring and operative to couple the at least one telephone device to at least one digitized voice channel.
A method for upgrading existing wiring in a building having at least two conductors to allow for coupling at least one telephone service signal to at least one telephone device in the building over the wiring, the method comprising the steps of:
- coupling an exchange side device in the building to the wiring, the exchange side device being operative to couple at least one telephone service signal to a digitized voice channel;
- and
- coupling at least one subscriber side device in the building to the wiring, the subscriber side device being operative to couple at least one telephone device to the digitized voice channel;
- wherein the wiring is operative to carry multiple time-domain multiplexed digitized voice channels.
A network for carrying multiple voice channel, the network comprising:
- wiring comprising at least two wiring segments, each segment having at least two conductors and each segment carrying at least one time-domain multiplexed digitized voice channel;
- and
- two coupling devices connected together by a respective wiring segment, each coupling device being couplable to at least one telephone device, and being operative to couple the at least one telephone device to at least one digitized voice channel carried over the respectively connected wiring segment;
- and
- wherein at least one coupling device is connected to at least two of said wiring segments.
A network for coupling first and second telephone service signals to at least one telephone device, the network comprising:
- an exchange side device;
- at least one subscriber side device;
- and
- a wiring extending between the exchange side device and the at least one subscriber side device, the wiring having at least two conductors, the wiring being connectable for carrying one or more time-domain multiplexed digitized voice channels;
- the exchange side device being connectable for receiving said first telephone service signal and being capable of passing said first telephone service signal into the one or more digitized voice channels;
- and
- the at least one subscriber side device being connectable for receiving said one or more digitized voice channels and coupling said one or more digitized voice channels to the at least one telephone device;
- wherein the wiring is connectable for concurrently carrying the second telephone service signal in a form of an analog telephone service signal in a telephone band using frequency domain multiplexing, and
- wherein the at least one subscriber side device is capable of coupling the at least one telephone device to said analog telephone service signal.
