[Asterisk-Users] PRI Errors: Here is where I am at...

[Andrew McRory]

FYI: I hope that this is not a "me" error and that Digium can squash this
bug (or new hardware fixes it). Either way, when this is over, perhaps I
can provide some troubleshooting documentation for these errors.

Subject: PRI Errors (HDLC Abort (6) on Primary D-channel)


Hello,

I called last week and got a ticket number (13329) but have not yet
received a call back. My T400P card that I use to serve my phone system
and take incoming V.90 callers is dropping all channels randomly. It is
currently configured like this:

			(T400P) <--> <ASTERISK> <--> SIP/VoIP/etc.
			|
			(Port1) ---- <now unused / previously LEC-PRI>
			|
			(Port2) ---> <Max 40000 / V.90 Dial-up users>
			|
			(Port3) ---> <Microcom isPorte / Fax Test>
			|
	LEC-PRI <-----> (Port4)

The system seems to be an excellent solution for my needs except for the
PRI errors (http://www.linuxsys.com/files/pritrubbl.txt). Lots of sleep
has been lost trying to determine the cause of the error. I have replaced
the server hardware, tried various asterisk releases, changed operating
systems, all to no avail. The worst part is that I have not found any
method to determine the exact cause of the error and the telco says "it's
not me".

In all the searching I have done I find that many others are experiencing
the problem but no real cause or resolution is described.

Althought I am ready to purchase a new card, I am not convinced that the
problem is hardware as the errors only occur with on the LEC-PRI span.
Span 2 and 3 never error out. I must fix this problem asap or search out 
alternatives immediately. Please let me know how to proceed.

Regards,
