 |
|
Hello,
Someone told me about using a Loopback plug for RJ-45 for testing if a
Digium Card gave him 'green' Alarm (for testing if the card had been
damaged by a strange voltage surge); would this have some bad side effect?
Thanks in advice,

Well, it's actually probably an RJ-48X interface, but who's counting.
If your question, though, is "would plugging a loopback-wired 8p8c modular
plug into the jack on the back of a T-1 card cause it any damage in
itself?", I can't imagine the answer would be "yes", no.
If you loop it and it stays in Red alarm, it's probably broken.
I can't speak to exactly what the alarm status stuff does if the port
you're looping expects to have a PRI plugged into it: I would expect
"Green, but no actual traffic", but I could be wrong, I'm a bit new on
that front.
Cheers,
