Abstract

An apparatus for providing bifurcated voice and signaling traffic over a cable telephony architecture by segregating signaling traffic and voice traffic and transmitting the respective traffic over two different mediums to a switch to establish a phone call.

Claims

1. An apparatus for providing bifurcated voice and signaling data over a network, comprising:

a memory, for storing protocols for interfacing with the network; and

a processor, coupled to said memory, for segregating signaling traffic and related voice traffic including information useful in establishing a communications link, for transporting said voice traffic between a calling party and called party, and for transmitting said voice traffic and said signaling traffic via different communication channels, wherein said voice traffic is switched to the same communication channel as said signaling traffic in the case of a loss of local power.

2. The apparatus of claim 1, wherein one of said communication channels is a data packet network.

3. The apparatus of claim 2, wherein said voice traffic is carried by said data packet network.

4. The apparatus of claim 3, wherein said voice traffic is subject to compression processing compatible with said data packet network.

5. The apparatus of claim 1, wherein one of said communication channels is a wireless network.

6. The apparatus of claim 5, wherein said signaling traffic is carried by said wireless network.

7. The apparatus of claim 1, wherein said apparatus comprises a Media Terminal Adapter-Cellular Transceiver (MTA-T) having integrated MTA and CT portions.

8. The apparatus of claim 1, wherein said apparatus comprises a Media Terminal Adapter-Cellular Transceiver (MTA-CT) having non-integrated MTA and CT portions.

9. An apparatus for providing bifurcated voice and signaling data over a network, comprising:

a memory, for storing protocols for Interfacing with the network; and

a processor, coupled to the memory, for identifying a call request, for establishing a signaling link for transporting signaling traffic to a switch via a first transport medium, and for establishing a voice path for transporting voice traffic to the switch via a second transport medium responsive to a determination that a called party answers, wherein said voice traffic is switched to the same medium as said signaling traffic in the case of a loss of local power.

10. The apparatus of claim 9, wherein the first medium is a wireless medium.

11. The apparatus of claim 10, wherein said signaling traffic is carried by said wireless medium.

12. The apparatus of claim 9, wherein said second medium is a data packet network.

13. The apparatus of claim 12, wherein said voice traffic is carried by said data packet network.

14. The apparatus of claim 13, wherein said voice traffic is subject to compression processing compatible with said data packet network.

15. The apparatus of claim 9, wherein said apparatus comprises a Media Terminal Adapter-Cellular Transceiver (MTA-CT) having integrated MTA and CT portions.

16. The apparatus of claim 9, wherein said apparatus comprises a Media Terminal Adapter-Cellular Transceiver (MTA-CT) having non-integrated MTA and CT portions.

17. An apparatus for providing bifurcated voice and signaling data traffic over a network, the apparatus comprising:

a data portion, for interfacing with a data network;

a cellular portion, coupled to the data portion, for interfacing with a wireless network;

a user interlace portion, coupled to the data portion and cellular portion, for interfacing with peripheral devices;

a Digital Signal Processing portion, coupled to the cellular portion and the data portion, for processing cellular and data information wherein the cellular information comprising the signaling traffic and the data information comprising the voice traffic; and

a battery backup portion, coupled to the digital signal processing portion, for detecting power failures, wherein upon the detection of a power failure, voice traffic is switched to a communication channel of said signaling traffic.

18. The apparatus of claim 17, wherein said data portion comprises at least one of a flash memory:

a random access memory;

an ethernet control processor; and

an ethernet transceiver.

19. The apparatus of claim 17, wherein said cellular portion comprises at least one of:

a cellular control processor;

a cellular transceiver; and

a memory device.

20. The apparatus of claim 19, wherein said memory device comprises at least one of:

a Battery Back up Random Access Memory (BBRAM); and

a Non-Volatile Random Access Memory (NVRAM).

21. The apparatus of claim 20, wherein said battery back up portion comprises:

a power failure detector.

22. The apparatus of claim 17, wherein said digital signal processing portion comprises at least one of a modem;

and

a Coder/Decoder (CODEC).
