a virtual circuit coupled to the BRAS and carrying VoIP traffic from customer premises equipment supported by a remote digital subscriber line access multiplexer (DSLAM).
9. The communication system of claim 8 , wherein the customer premises equipment includes an internet protocol (IP) phone and wherein a first point to point over Ethernet (PPPoE) session is established over the virtual circuit between the BRAS and the IP phone.
10. The communication system of claim 9 , wherein the first PPPoE session is dedicated for carrying VoIP traffic and wherein a second PPPoE session circuit carries other type of data traffic over the virtual circuit.
11. The communication system of claim 9 , wherein the second PPPoE session is terminated at an Ethernet switch and wherein the Ethernet switch is responsive to the IP phone.
12. The communication system of claim 9 , wherein the second PPPoE session carries traffic to an internet service provider to provide access to the internet.
13. The communication system of claim 8 , wherein the VoIP network comprises a Session Initiation Protocol (SIP) proxy module, a software telephony switch, and a physical telephony switch, the physical telephony switch coupled to the media gateway and coupled to a public switched telephone network.
14. The communication system of claim 13 , wherein the SIP proxy module is coupled to the access router and to the software telephony switch.
15. A communication system comprising:
a voice over internet protocol (VoIP) network having an access router;
a broadband remote access server (BRAS) coupled to the access router via a tunnel connection that is dedicated to carrying communication of VoIP traffic from the BRAS; and
a virtual circuit terminating at the BRAS and carrying VoIP traffic via a first PPPoE session and carrying other data traffic via a second PPPoE session from customer premises equipment supported by a remote digital subscriber line access multiplexer (DSLAM).
16. The communication system of claim 15 , further comprising internet service provider equipment, wherein the second PPPoE session is between an Ethernet switch at the customers premises equipment and the internet service provider equipment.
17. The communication system of claim 15 , wherein the customer premises equipment comprises an internet protocol (IP) telephone and wherein the first PPPoE session is between the IP telephone and the access router of the VoIP network.
18. The communication system of claim 17 , wherein the IP telephone is configurable as to selection of a communication protocol.
19. The communication system of claim 18 wherein the communication protocol is one of PPPoE and IP over Ethernet.
20. The communication system of claim 19 , wherein the IP telephone includes a PPPoE function key.
21. A voice over internet protocol (VoIP) telephone apparatus comprising:
an encoder and decoder module responsive to a handset of the VoIP telephone apparatus;
a data processor responsive to the encoder and decoder module;
a point to point over Ethernet (PPPoE) client software module responsive to the data processor;
a memory to store PPPoE session information; and
a PPPoE function key that is used to launch a PPPoE communication session.
22. The apparatus of claim 21 , further comprising a display screen and a telephone keypad, wherein the display screen includes a PPPoE indicator that is configured to display a connection status of a PPPoE session and wherein the keypad may be used by a user to enter PPPoE login information.
23. The apparatus of claim 22 , wherein the PPPoE login information includes a service provider domain name, a PPPoE login, and a PPPoE authentication password.
24. The apparatus of claim 22 , wherein the PPPoE login information includes an internet protocol address of a remote broadband remote access server (BRAS).
25. The apparatus of claim 22 , wherein the PPPoE login information entered at the keypad is stored in the memory.
