[c-nsp] 877 ADSL router does not work

[James O'Farrell]

Have you tried to hard code the dsl operation mode,

For example; dsl operating-mode ansi-dmt

(bear in mind you may have to reset the interface and/or router for this
change to be made)

I have come across this issue on various 857's it seams to depend on the
dslam that you are connecting to.

JOF

What do "show dsl interface atm 0" and "show controllers atm 0" say?
