[asterisk-users] Using a Loopback Plug for an RJ-45 Ethernet Interface for testing a Digium Card
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, -- Jose P. Espinal

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.
