[asterisk-users] Using a Loopback Plug for an RJ-45 Ethernet Interface for testing a Digium Card

2008-05-17 Thread Jose P. Espinal
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,
