i´m trying to configure the abovementioned router with an adsl access. we have a fixed ip add from our isp operator with a mask of /32. the router does not allow this mask and our operator cannot/will not change the mask unless we ask for another mask which entails more cost.
can anyone help me with this?
regards

i´v done some troubleshooting using;
debug atm events
debug atm packets and
sh dsl int atm
all results that i got were the required ones.
it seems like the router is definately training with the dslam on the other side.
thanks

You don't want to debug atm - the sh dsl int atm will show you if the ATM layer is up. Debug PPP. In particular look at the IPCP messages. If you can't figure it out from that try posting the output of a debug ppp negotiation in this thread.
Edit: At a second glance your config appears to be missing encapsulation on your ATM sub interface.
Try using PPPOA instead of the PPPOE client. Remove your current pvc configuration and try this:
interface atm 0/0/0.1 point-to-point
pvc 0/35
encapsulation aal5mux ppp dialer
dialer pool-member 1

the sh dsl int atm does show that it is up (SHOWTIME) appears. When I try the ppp debug nothing happens.
I think that a call never does initiate. I think that the problem lies with the dialer/dialer list.
I`ve looked nad tried various exmamples but to no avail.
I have installed many soho adsl products but never had any problems. This is the 1sy time I install adsl using a wic.
By the way i´m not sure if its important mentioning that I am in Europe.
thanks

Do you use ADSL over POTS or ADSL over ISDN? I mention this because you need the WIC-ADSL-I for ADSL over ISDN. The WIC-ADSL works over POTS only.
If your router has a build in ATM interface you should make sure that it supports the correct ASDL mode ...
Greetings from germany (we use ADSL over ISDN)

hi matthias,
it´s adsl over pots. and i´m using a 2811 modular router with a wic-1adsl.
i think that the problem lies within the dialer interface configuration.
when i do debugging, the wic does train with the dslam on the operator side. BUT when i do debug ppp,
i get no result. this means that the dialer isn´t working. i think! it´s not even trying to dial out. correct.

Hello fcatalao,
i had a look at your config and i haven't four your decalation of interesting config or a "dialer persistant" statement.
You have the "dialer-list 1 protocol ip permit" statement but you have missed the appropiate command in your dialer profile.
Try adding a "dialer-group 1" or command to your dialer interface.
If it still doesn't work you could use the debug dialer commands.
