[asterisk-users] Audio when card is in condition yellow

Usually a card is supposed to send yellow alarm (so it's transmitted)
when it detects LOS (loss of signal) on the T1, or essentially a red
alarm condition is detected.  So if yellow is being sent, it means
that at least one end is not able to sync up the line, which means
you'll have junk/garbled audio potentially.

Hope that helps,
Matthew Fredrickson
