Since a hard reset to correct a VM down, the PRI in an Option 11 is bouncing- RLS RED ALRM, RLS CTS DOWN, EST CONFIRM. every 3-5 minutes. I think the last changes to remove 2 T's and start the PRI may not have been saved, but it was done by a previous tech, who is no longer available. I'm not up to speed, but worked on these years ago. I contacted Bell to check the PRI, but I see the old T's CC lamp flashing. The first 3 slots in Cab 0 (Main) have TMDI's, but only the third is in use.
