Help!! Cisco 678 CAP modem WAN not functioning mtin 06-05-06

I have worked with my ISP to configure a Cisco 678 CAP version modem
and have failed to get it talking to qwest's DSL service.

After follwing the full qwest config routine at:

http://www.qwest.com/internethelp/modems/cisco675_678/pdf/11295_Cisco_PPP_DynOrSingleStaticIP_053005msl.pdf


I get no WAN lights and no connection as reported by Cisco Commander or
my ISP.

Can anyone offer help? I get no errors when modem boots and the latest
firmware is installed.

Thanks!
- Larry

Hasn't Qwest switched all its circuits to DMT?

Bert -

Thanks for the reply, I'm currently on hold with qwest tech support.

First they told me that new DSL connections are only DMT, but then
after chatting with their back room help said the Cisco 678 CAP or DMT
should work with a new connection .

Any ideas?

Yeah; the person you're talking to is wrong (unless I'm ->seriously
misinformed [and I'm sure if I am, I'll find out about it real fast :-)]).

You'll need your 678 flashed with firmware matching the mode of your line,
CAP or DMT, whichever.

If you've stayed with a very old line (slower that 1.5Mb) you might still
have a CAP circuit, but when any line is upgraded to 1.5Mb or faster, they
also convert to DMT.

the Qwest tech help guy (in the Phillipines!! - and very polite) double
checked that a Cisco 678 Cap unit can work with a new line, so they
verified that we have no connectivity and will send out a lineman to
check my connection.

While was on the line with him, I took the modem outside, plugged it
into the box and re-verified we have no connectivity.

Yowza!! ??????
