[clue-tech] Cisco 678 and Qwest DSL

[F.L. Whiteley]

Mine follows.  I see a couple variances.

I've seen this elsewhere at a customer in Wheatridge.  32k in on
256k/256k service.  M1000 trained up fine at 256/256, and now it's on
1.5Mb.  Qwest tech checked at the demarc and it trained fine on his test
bed.  Saw it once in Greeley.  Turned out to be an obsolete line
conditioning card in the circuit.  Worked once removed.  Hear anything
when you punch 1 on the dialpad?  Know if you're on Central Office or
Remote Terminal?  Melting snow?  Have Qwest run a line test.
