Cisco 2611 Async Modem Dial Configuration??

OK I'm trying to configure my 2611 to dial out on a modem connected to one of the serial interfaces on a WIC-2T module. So here is the scenario:

Cisco 2611 with a WIC-2T (Sync/Async) interface module fitted. CAB-SS-232MT cable fitted between Serial 0/1 and standard 56K modem.

So far I have configured Serial 0/1 as follows:

interface Serial0/1

physical-layer async

ip address negotiated

encapsulation ppp

dialer in-band

dialer-group 1

async mode dedicated

ppp authentication chap callin

Now I just need to work out how to configure the Dialer configuration. I know I need to configure the 'Chat-Script', which I believe contains the modem AT commands and somewhere I need to include the Username and Password details for the CHAP authentication.

The ultimate aim is for me to configure a static route something similar to below:

ip route 192.168.20.0 255.255.255.0 Dialer1

Whereby any traffic routed to the 192.168.20.0/24 network will cause Dialer1 to initiate the call on the modem connected to Serial 0/1, authenticate with the remote network and then route traffic.

Does anyone have any ideas? or sample configurations?

Any help appreciated.

Re: Cisco 2611 Async Modem Dial Configuration??

WIC-2T will not support Async connection..You may have WIC-2A/S card which is described in following url

http://www.cisco.com/warp/public/107/wic-2as.shtml

Now configuring it to dialout is just like configuring DDR using a modem connected to a router..You may not need a dialer interfcae, you can just configure the dialer map command if you know the name and ip address of the other side interface. Then just add one command under serial interface like

dialer map ip 1.1.1.1 name abcd 123456

where 1.1.1.1 is ip address of the other side interface and "abcd" is the name and 123456 is telephone number

Vwer similar config which is discused in following url for interface serial 2.

Or you can use the similar config as described in

Tejal,

I'm sorry to say that the WIC-2T does support Async connections. I actually managed to work out the config in the end. I've posted it below for your information. It works perfectly and provides a dial on demand solution for me.

Current configuration:
