6. The method of claim 1 , wherein the internet service provider has a remote authentication dial-in user service server, and wherein the providing access comprises instructing the internet service provider remote authentication dial-in user service server to initiate a protocol session with the subscriber.

7. The method of claim 1 , wherein the trigger is an automatic flexible route trigger.

8. The method of claim 1 , wherein the trigger prompts a query to a control node, and the control node responds to the query by writing the internet service provider's telephone access number into a calling party field and a telephone access number for the shared modem pool in a called party field.

9. A system for providing increased bandwidth for an internet service provider comprising:

a control node communicating with a first switch, the first switch provisioned with a trigger on a trunk line for the internet service provider and operated when no line is available between the first switch and the internet service provider, said control node comprising a database for routing a telephone call to a shared modem pool via a second switch, the control node providing for routing a telephone call in response to the trigger, wherein said shared modem pool is non-exclusively shared by the internet service provider with at least one other internet service provider;

a proxy authentication server communicating with an access server, said access server communicating with the shared modem pool,

wherein the telephone call is routed to the shared modem pool, the access server answers the telephone call, and the proxy authentication server communicates with an authentication server for the internet service provider to establish a dial-up session for the telephone call.

10. The system of claim 9 , further comprising an integrated services digital network line to functionally connect a network for the internet service provider to a router adapted to communicate with a network for the access server and the proxy authentication server.

11. The system of claim 10 , wherein the proxy authentication server is to receive an instruction from the internet service provider, said instruction to authorize changes to the database.

12. The system of claim 9 , wherein the trigger is an automatic flexible route trigger.

13. The system of claim 9 , wherein the control node is to write a telephone access number for the trunk line in a calling party number field of a call setup message.

14. A method for allowing an internet service provider to dynamically expand a number of telephone lines and modems available to subscribers to the internet service provider, the method comprising:

activating a trigger provisioned on a trunk group of the internet service provider at a first network component serving the internet service provider when a subscriber makes a call to access the internet service provider but no lines are available in the trunk group of the first network component serving the internet service provider to connect the subscriber to the internet service provider;

in response to the trigger, forwarding the call to a second network component serving a shared modem pool, the shared modem pool non-exclusively shared by the internet service provider with at least one other internet service provider; and

providing the subscriber access to the internet service provider via the second network component and the shared modem pool.

15. The method of claim 14 , wherein the providing access includes the second network component terminating the call to a multi-line hunt group.

16. The method of claim 15 , wherein said providing access includes the multi-line hunt group connecting the call to an access server in communication with a proxy authentication server.

17. The method of claim 16 , wherein the proxy authentication server determines the internet service provider the subscriber is trying to access.

18. The method of claim 16 , wherein the proxy authentication server instructs the internet service provider's authentication server to initiate a protocol session with the subscriber.

19. The method of claim 14 , wherein the internet service provider has an authentication server, and wherein providing access comprises instructing the internet service provider authentication server to initiate a protocol session with the subscriber.

20. The method of claim 14 , wherein the trigger is an automatic flexible route trigger.

21. The method of claim 14 , wherein the trigger prompts a query to a control node, and the control node responds to the query by writing the internet service provider's telephone access number into a calling party field and a telephone access number for the shared number in a called party field.

22. A system for providing increased bandwidth for an internet service provider comprising:

a network component communicating with a first switch, said network component comprising a database for routing a telephone call to a shared modem pool via a second switch in response to a trigger provisioned on a trunk line for the internet service provider on the first switch, said trigger operated when no line is available between the first switch and the internet service provider, wherein the shared modem pool is non-exclusively shared by the internet service provider with at least one other internet service provider; and

a proxy authentication server communicating with an access server, said access server communicating with the shared modem pool, wherein when the telephone call is routed to the shared modem pool, the access server answers the telephone call and the proxy authentication server communicates with an authentication server for the internet service provider to establish a dial-up session for the telephone call.

23. The system of claim 22 , further comprising an integrated services digital network line to functionally connect a network for the internet service provider to a router to be in communication with a network for the access server and the proxy authentication server.
