RE: [Asterisk-Users] Asterisk and Mitel SX 200 Slip and Frame Errors causing Major Ala rms

[Dennis Walker]

I use to do the same thing with an SX200 digital, and had the same problem.

I could not get the slips to go away no matter what I tried.

My sx200 would go offline once a day in the middle of the night luckily 
once the limit was exceded.

But I did find that down in the t1 parameter settings you can set the 
limits higher.  I maxed them out and the problem went away, it would reset 
the count in a rolling 24 hours luckily the slip count just stayed below 
the limit.

I think you get to them in the system config, ds0 settings.  The same place 
you set the t1 parameters.  I'm can't remember exactly the old SX200 has 
been go for 6 months now.

Subject: 	[Asterisk-Users] Asterisk and Mitel SX 200 Slip and Frame 
Errors	causing Major Ala rms

We have integrated an Asterisk (TE110P) and a Mitel SX200. We usually get
over  500 frame errors and over a 500 slip errors per hour. When the errors
reach 1000 per hour the Mitel will take it's T1 card offline. At that point
no calls can be routed from the Asterisk server to the Mitel and the TE110P
reports a Yellow alarm.

What can be causing all these Frame and Slip errors? We have been working
with a Mitel tech to get all the configurations correct and we still 
haven't
been able to resolve the issue.

We are currently connecting via crossover so we'll try a straight through
just for kicks. We have a spare TE110P so we are going to try that. I just
don't know enough about these errors to know what to try next.	

Any other thoughts?????
