Hello All,
We have an NEC 2000IPS with a PRI for all incoming calls and another T1 for all outgoing calls. Lately we have received many complaints of intermitant phones calls,similar to a cell phone dropping in and out. The error logs show "DTI line failure Power failure kind Data F4 FF FF FF FF FF FF FF" and "DTI returned to normal" Those are the only errors. I'm not real sure as to what to do with this information. I can do basic programming and moves and changes but this error is out of my comfort zone. Thank You.
 
If the T-1 card is "line" powered, by telco then you may have a telco issue, or a cabling issue. Check your cross connects to the T-1 card. The only other suggestion I have is that it may be the card. try replacing it.
