HWIC-2SHDSL not working

Unanswered Question
Mar 29th, 2012


I have a 2911 running 15.0(1r)M12 with an HWIC-2SHDSL but I'm getting the following error and ATM remains down/down

HWIC_SHDSL-7-EVPOSTERR: 1: SHDSL 0/0/0, EV(3) failed - No evBuffer

%HWIC_SHDSL-5-DSLGROUP_UPDOWN: SHDSL 0/0/0 dsl-group(0) state changed to administratively down.

Configuration is simple and similar to the configuration we have on our 1800 series.

controller SHDSL 0/0/0

dsl-group 0 pairs 1

  shdsl annex A-B

I can´t find information about this error, any ideas?

How do you know that the circuit is working ?

Note: the version you posted is rommon, not IOS. Update IOS.

We know the circuit is working because we used to have a 2821 and we just upgraded to the 2911.

BTW, the IOS is 15.1(4)M1

Leo, being an ISR G2, this router runs universal image.

And I don't think this hardware requires any optional license to work.
