Errors running 1:8 pattern on VWIC-2MFT-T1 card

[wsnider]

Issue discovered while stress testing two T1s. T1s test clean h-2-h when cable removed from VWIC-2MFT-T1 (T1 (2 port) Multi-Flex Trunk WAN daughter card), but can not run 1n8 test pattern to CSU loop. Tried this with two different cards with same result.

Does anyone know of any issues like this?

The 1:8 pattern is the borderline test pattern that invokes B8ZS. If you are getting errors on this pattern then you have a line code mismatch somewhere on your line (Eq, CSU, Telco, DACs, etc..)
