That is the T1/PRI monitor screen it shows the activity on the different channels and if it is in an alarm status the state changes. 14 is good I don't see where it says loop back enabled
perhaps it just saw a loop back condition at one time. About the only thing you can do in that screen is hit Space bar to refresh. Or hit R then it will ask channel to reset. (Never used that) but if you type in 33
and hit enter it resets the card. Of course it drops all calls during reset. Then wait a few and hit space bar to refresh or go out and back into screen.
Can't remember what manual I sent you but the codes are explained on pg 33 of older manual and pg 94 of the Eclipse manual.

If working all good.
