Alarm issue with E&M with Default I/F ISDN 1

[Missy8s]

I have a client that keeps receiving Alarm 75 (Check ISDN service provider)on T-1/E&M trunk configuration, the alarm keeps appearing after I clear the event log.

Integra telecom wants me to change the I/F Level from ISDN to ISD/TT but I am very leery of that change.

We swapped out the T-1 card already and then we found out they changed their CSU/DSU to a SiP version.

The client does not want PRI.

They have taken the circuit off of the CSU/DSU and now we are connected directly to the NIU.

Any suggestions on what settings I should check or check prior taking that action?

The alarm will keep appearing if it sense something is wrong.
Clearing it will not turn it off.

"ISDN to ISD/TT but I am very leery of that change."

Whats the worse that can happen? bad sound quality?
