Here is some background. Can't connect remotely via modem and can't fax out LD. Both have been working fine for years and trunking is a PRI. The modem and the fax machine are using the two analog station ports on the onboard ASU (Bay1/Slot13/Ckts 03 & 04) of the MX so I suspect it as the culprit or the PRI provider has made a change although they deny making any.

Having a few spare analog station ports on an ASU II, I moved the fax and modem over to those two ports and changed the TEN and COS and COR in Form 9 to match. Sending LD test faxes still don't complete even though it sounds good (the call gets setup and some squealing goes on) but then nothing. Any suggestions?

Voice calls are fine, but most data can't synchronize? Sounds like you've got clocking problems on your PRI. Is there a clock module installed? Is it set up properly in form 44? In maintenance, is the PRI sychronized, or is it freerun?

Thanks 55'r : I haven't checked on the clocking questions you asked. I failed to mention that local faxes work fine, so I question if it is a clocking problem.

I had the exact same problem on a Windstream PRI. They were adamant that there were no changes made to the PRI. I messed around with the clocking and got it to work. Then I found out they changed the DMS switch. I still don't know how the PRI worked, at all, but I changed the protocol to NI-2 from DMS and everything worked.

They are always slow to admit that they have made any changes or that it could their fault.

Yup. It turned out to be Telco. Thanks.
