B410P BRI Card Testing With Patgen / Pattest

Hello,

I have a card here at the office that I’m trying to validate with some tests. For now I’ve followed the instructions available here:
http://kb.digium.com/articles/Configuration/Back-to-Back-Pattern-Test-for-BRI-Adapters
.

I get this kind of output:

[..]
(.Error 44119): Unexpected result, 255 != 0, 1 bytes since last error.
(Error 44120): Unexpected result, 255 != 0, 1 bytes since last error.
(Error 44121): Unexpected result, 255 != 0, 1 bytes since last error.
(Error 44122): Unexpected result, 255 != 0, 1 bytes since last error.
(Error 44123): Unexpected result, 255 != 0, 1 bytes since last error.
(Error 44124): Unexpected result, 255 != 0, 1 bytes since last error.
(Error 44125): Unexpected result, 255 != 0, 1 bytes since last error.
(Error 44126): Unexpected result, 255 != 0, 1 bytes since last error.
(Error 44127): Unexpected result, 255 != 0, 1 bytes since last error.
(Error 44128): Unexpected result, 255 != 0, 1 bytes since last error.
(Error 44129): Unexpected result, 255 != 0, 1 bytes since last error.
(Error 44130): Unexpected result, 255 != 0, 1 bytes since last error.
[…]

This goes on continuously, like a massive flood, not a small burst in the beginning like the KB article mentions.

Would this be the kind of output that matches a problem card or something may be wrong in my setup? I’m using DAHDI 2.8.0.1.

Any input appreciated, thanks!

Regards, Rodrigo

    I’m not sure if my previous e-mail went through, it contained a link so it may have been blocked, Apologies if this is a duplicate.

  • patlooptest works by sending an incremental sequence of bytes down the transmit side (1,2,3,4,…). Then on the receive side, it watches for the same sequence.

    In this case, you aren’t receiving any valid patterns. It’s likely a configuration error (unless the card is known bad). You might try double checking your test procedure.

  • Hello Russ,

    Actually this was with pattest and patgen, not patlooptest. I don’t know if I can use patlooptest with B410P, should I?

    Thanks.

  • Sorry for the confusion. They all do the same thing. Patlooptest is patgen + pattest combined into one program. Just use whichever is easiest for your scenario.
