To do this GOTO LD 36 from maintenace phone and type TRK L M. I've not been able to get this to work on PRI with trunk type tie but works fine on all others.

It doesn't work on PRI with trunk type DID either. I wouldn't think that it would work on PRI in general because it's the PRI's D channel that sets up the call. If you sieze an individual trunk member of a PRI, you're bypassing the D channel. Siezing an individual B channel won't allow you to place a call because the dialed digits are handled by the D channel. They're not outpulsed over the B channel like they would be over a channel of a non PRI T-1.

TRY CHANGING THE SEARCH TO RRB THEN IN LOW TRAFFIC LIKE AFTER HOURS KEEP DIALING UNTIL YOU HIT THE TRUNKS YOU WANT. I'VE HAD PRETTY GOOD LOOK WITH THIS METHOD IN TROUBLE SHOOTING

FORGOT YOU CAN ALSO DISABLE THE CHANNELS TO GET WHERE YOU WANT TO GO

You're right. It does work on PRI DID. I stand corrected.
