I am working on getting a PRI working on a 200EL that doesn't have a PRI license (0 digital links).

The Adtran Atlas 550 can convert the PRI to T1 and pass calls through. I have this working perfectly on a 200Light LW 15 for years.

I copied my programming over to the 200EL LW19 but the Atlas T1 will not handshake with the Mitel. There are alot clock slips.

The Mitel is set for D4/AMI and there are no alarms on the Mitel. Only the Adtran Atlas is showing ERROR with alot of clock slips

Adtran tech support confirms all of my settings are good but it's the Mitel side I think that needs some fine tuning.
In the long run the Atlas is more stable than the Mitel PRI card so I am hopeful I can get this going with some help!

Anyone else run into this problem.

Is the clock set properly in form 44?
The clock on the Main Control Card could be bad.

But is the T1 with the problem in 3/6? And tell me it's REALLY in slot 11 and 6 is empty.

bay 3, slot 6, it's a light cabinet

i think i figured it out: set the line coding on the Mitel to AMI&ZCS in form 42 and it sync'd up good, no slips, no errors.
