I have a merlin magix with a 100dcd card running a PRI. Lately the system has been dropping calls. I checked with the LEC and the said "everything was fine" on their end. I checked the error log a found alot of slips. I changed out the 100DCD, worked fine for a half day. Now the same thing, lots of slips and dropped calls. Is there something in the processor that could cause the timing to be off or should I pursue the local LEC.
