Cisco 887VA - "Controller VDSL 0 is DOWN"

I'm trying to configure Cisco 887VA as an ADSL router but can't even get past the first post - the modem / controller is stuck in DOWN state and I don't get "showtime". I triple-checked the physical connectivity, replaced the phone cable, upgraded the firmware but got nowhere.

Here is a couple of outputs:

wlgrt1#show interface ATM 0

Whatever I do all I get is "Controller VDSL 0 is DOWN" and "Modem Status: Idle". The modem used to work in our other office on a VDSL link (this office only has ADSL).

Any idea what to do?

Thanks!

It is not detecting any xDSL signal.  How confident are you that the circuit has xDSL turned on?  Can you test it with another device to confirm it?

It used to work with ISP provided modem but never with this Cisco box. I will try to put the old modem back in tomorrow. Thanks for the suggestion.

Did you ever find a solution to this?

Hello Michael,

>> The modem used to work in our other office on a VDSL link (this office only has ADSL).

ADSL and VDSL are different transmission standards, I don't think you can connect a VDSL CPE to an ADSL line unless backward compatibiity is supported and configured.

ADSL2+ is backward compatible with ADSL.

But VDSL is a different matter.

try under controller vdsl 0

operating mode auto

Hope to help

Giuseppe

The 887VA can do both VDSL and ADSL (that's what the "VA" in its product code stands for).

Hi, i assume your PVC is correct for your country, under the ATM interface. Have you run any debug's on the ATM line to see if any errors crop up when it tries to synch? Phil
