[Asterisk-Users] HDLC Bad FCS / HDLC Abort

[Alex G Robertson]

Some news.....

It is not caused by transmission lines, conectors or anything like that.

The telco tecnician just came here and analyzed the circuit and he got no erros!


He sugested me to loop my PRI port in the balum attached in my asterisk box. 
And.... Surprise...

I got the same errors!
The error is on my hardware/software.
