Is this an NFAS problem? Our PRI lines all appear as a single trunk at the telco, controlled by the NFAS functionality across as many PRI lines that are included in the NFAS group. At least that is how the switch guys described it to me. All I do at my end is make sure the second, third, etc. card are set up as being a member of the NFAS group, and determine whether I am going to add additional d channels for redundancy. If the PRI lines are not part of an NFAS group, then there must be some sort of hunting or rollover involved. It is very similar to the way our incoming T1's are handled, they all are piled into one big group as available lines with no hunting set up at all. While hunting would be beneficial in some troubleshooting situations we had it get messed up so many times they moved to this mode. Any time we add lines the switch tech just adds the transport layer to the group and whamo, there are additional lines at our site that work without the intervention of some other "programming tech" at the telco.
