TIE trunks problem

[bluemilkyway1982]

Hi everyone,

I am configuring TIE trunks between M1 R 25.40 B. After configuration completed, I can make calls using ESN. But after 15 minutes, some lights on PRI card face are in red and a M1 message display as the following:

DTA0301 loop A slip deletion has occurred on PRI2 loop

If anyone knows this problem please give me a hand.

Thanks so much,
DN

Usually only a few causes for slips. First Clocking is this your only link off switch if so is it set as your clock source, if not is your clocking looking ok. Is CRC on/off at both ends of Tie. Other than that you may have faulty hardware (although last choice).
