Guys,


Is there any documentation that explains what the output of this commad mean. I am troubleshooting a fxo port and from this output it l ooks like I have a cable problem. I am only saying this because I had a similar issue and the outpur was Register 29 = 0XCE and it turned out it was a cacling issue.

I will like to know what to make of the results.


What does Register 29 = 0xCC or 0xCD mean?

Aok, I think you know already that test commands and internal data and registers are undocumented

Isn't that the register supposed to reflect presence of loop current ?

I've always tought that the same can be done trying to place an outboud calls, it will fail with a 'no dialtone' in debug vpm signal.

I always expect that value 0x33 reflect the presence of a loop current or that a voltage is present on the line. But I have just tested the line now and it works! Thats odd and interesting.
