Message 225 - Loopback test failed
Explanation: Message printed as a result of a serious selftest failure.
The LED on the back of the card will be RED or OFF.
The card will be unusable and all terminals configured

the tta command to view terminals configured on the

the Mux card. Note other Mux cards (if any) will
continue operating normally.
