GPRS modem connection to 2620 router

[balsutiev.s]

Hello!

I have WaveCom GPRS modem I'd like to connect to 2620 router. So, 3 questions appeared:

1. How to configure router in order to it says GPRS modem connected to AUX port to start GRPS session. (In ordinary way, i can use AT command to dial *99# or *99***1# commands)

2. How to configure AUX interface to get IP automaticaly from network after GPRS session became active?

3. If it possible to make routing to any network through that GPRS modem?

Thank you in advance for advices or links to docs(I could find what I want at this HUGE cisco library :) )!

General Packet Radio Service/Code Division Multiplex Access (GPRS/CDMA) modems are normally connected to a serial interface of the mobile access router.The following link can help you in this.
