For us, and we may all be on the same team here it seems. After patch MPLR26045 was removed problems persisted with the circuits. Occasionally they will lock up. It appears to only be on circuits coming from the ULIC cards that are located behind BRSC cards. The CS1000 also has ULIC cards that are only behind the MISP card. These work flawlessly. MISP cards have been swapped as have the BRSC cards. The problem persist. This is Jeremy, btw.
