Actually, I passed this one the first time around, albeit with a 670
(650 needed). I felt a little guilty until I found out that our
resident CCIE passed with a 690.
So take your failure with a little grain of salt. Poor CID performance
has nothing to do with poor design ability.

As I understand it, you can't use a 675 to connect to PacBell, because
of the DSLAMs that they use. The 675 uses rate-adaptive CAP encoding (I
believe GTE and US West use these DSLAMS), PacBell uses the Discreet
MultiTone (DMT) ANSI T1.413 Issue 2 standard available on the 677 and
the 827.
