Re: Tn 771
A G3i really only requires one TN771. Only a critical reliability PBX must have a TN771 in each port network and a G3i cannot be a critical reliability PBX. I usually recommend that people put a TN771 in each port network that contains an ISDN T1 for reliability, but it is not required.
Having a TN771 in each port network will certainly not hurt and it is possible that your latest upgrade made that necessary but the documentation that came with it should have said something.
The Processor Interface board is the processor connection to the packet bus and yours is probably a TN794/TN2400 sandwich board. But this is not the duplication interface. So what was unseated? Was it the PI board or the Duplication board (TN792)? Either one would have taken SPE A out of service and alarmed the switch.
