Ran into a similar problem mixing the T1 VWIC's (when they were new)
and WIC-1DSU-T1's. One type of controller reported the bandwidth as
1536kbps, the other as 1544kpbs, and (as would be expected) they
weren't installed as ECMP paths. Workaround was to simply manually
adjust interface bandwidth statement. (Don't believe we ever raised
this to TAC to see if there was a bug to address the discrepancy).
