Install router with async interfaces (integrated modems)

Hello,

This is the second time I start this conversation, only this time with a little bit more information.

Hello,

We want to migrate 30 computers with modems in it. Currently they dial into a NT server but we want to migrate them to a Cisco 1841 with integrated modems.

I have experience with ISDN router-router connections, but not with computer async-router connections.

Do I need to define in the Cisco 1841 all type of modems that these computers are using using to dial-in. Isn't possible to create a simple config that's useful for all the 30 computer modems to dial-in? For note, the Cisco 1841 has integrated modems, so we do not need an external modem to communicatie with remote computers.

As attached a diagram, config and sh version.

I hope someone can help.

Regards,

Peter

Re: Install router with async interfaces (integrated modems)

Use the interface group-async command to create and configure a group asynchronous interface. The following example shows a group asynchronous configuration for a Cisco AS5300 access server loaded with one 4-port ISDN PRI card and 96 MICA modems:

Router(config)# interface group-async 1

Router(config-if)# ip unnumbered loopback 0

Router(config-if)# encapsulation ppp

Router(config-if)# async mode interactive

Router(config-if)# peer default ip address pool dialin_pool

Router(config-if)# no cdp enable

Router(config-if)# ppp authentication chap pap dialin

Router(config-if)# group-range 1 96
