Need help with hookflash.

I have an Eclispe2 6.0, 3 nodes (4 cabinets each) networked with T1s. CO lines are on LSC with daughter boards.

I can hookflash the CO lines in cabinet 1 and 2 of each node, but I cannot hookflash any CO lines in cabinets 3 & 4 of each node. This is the same if I press the flash key, softkey, or feat 330. Hookflash in the trunk groups is enabled. I can flash the CO with my buttset.

Any suggestions?

Thanks

Tony
