[c-nsp] 2811 router doesn't recognize T-1 WICs?

[MADMAN]

   Concerning the WIC-1DSU-T1-V2 we have been ecperiencing many problems 
and have a TAC case opened.  So far we have identifed twi issues that 
Cisco has bugs id's assigned to.

- WIC runs for 2 hours, 17 minutes then goes down
- High number of T1 errors seen with V2 card, no errors seen on same 
line with V1 card

   These are Cisco internal bugs so I can't provide a bug ID.  Though 
these specific cases may not reflect your experiences me thinks the V2 
has multiple issues.
