DSL issue on 3640 router with ADSL WIC

We have an ADSL WIC in a 3640 with a T1 which is normal mode of use unless
the T1 fails. We cannot seem to bring up a connection with the ADSL line and
see this all the time.

00:19:59: Vi1 CHAP: I CHALLENGE id 241 len 38 from "RASI1NRP2.Ilford2"
00:19:59: Vi1 PPP: Sent CHAP SENDAUTH Request to AAA

We are a UK based company connecting through BT, so some settings will be
different from the US.

When T1 is up we see

Interface IP-Address OK? Method Status

up
FastEthernet0/0 213.214.215.1 YES NVRAM up

When T1 is own we see

SO Dialer is coming up OK, but does not get an IP from our ISP's radius
server ?

Config below.
interface ATM0/0
no ip address
no ip mroute-cache
atm vc-per-vp 256
no atm ilmi-keepalive

dialer-list 1 protocol ip permit


We do not see any authentication attempts on the radius server at all ?

Any help appreciated.

Might have made things better - I now get

nterface IP-Address OK? Method Status
Protocol
ATM0/0 unassigned YES NVRAM up
up
FastEthernet0/0 213.214.215.1 YES NVRAM up
up
Serial0/1 213.214.215.1 YES unset up
down
Virtual-Access1 unassigned YES unset up
up
Dialer0 unassigned YES NVRAM up
up

I removed

and added
ppp chap hostname
ppp chap password 0 password

Gary,

try this:

Router#(config)interface dialer0
Router#(config-if)ip address negotiated
