My favorite circuit-ids were those from MFS where it had the service type (2 chars i think) + a pop-code + z pop-code + service count number.

We could then tell what pop/facility everything was handed off at easily enough.  I think my house even got a MFS pop code at one time due to the T1 which was there.
