I have recently purchased 2 857W boxes and no matter what I try I cannot get the ATM0(ADSL) interface to connect. The site I am testing from currently has an 837 which works fine (2Mb down/512Kb Up, line in the UK).
I have tried various ios images from the first to the most current and the same problem remains.
Any help/ideas would be much appreciated
Thanks in advance

For some reason the DSLAM returns an 0x22 code during the connection. I assume the DSLAM has sent the code as a 0x10 code has come back.

We got this sorted (with help from Cisco TAC):
On the 877/1801 (presumably same on 857), we had to say:
int atm0
dsl operating-mode ansi-dmt
instead of:
dsl operating-mode auto
We also need to do a shutdown/no shutdown and sometimes pull the DSL cable if changing this setting.
We're trying to get details from BT of the DSLAM make and firmware version, on the lines where we've seen this problem, to feedback to Cisco.

This error is usually related hardware problem and Please verify the encapsulation with the Service Provider as well.

Had the same issue. Change the dsl operating mode to dsl operating-mode ansi-dmt no auto.
This should get you working.
