The loopback itself is listed in the Conditions window. For example, the window would list the
LPBKFACILITY condition for a tested port. (The Alarms window would show the AS-MT condition which
means that alarms are suppressed on the facility during loopback unless the default is set to alarm for loopback
while in AS-MT.)
With a client-side SONET or ANSI facility loopback, the client port service state is OOS-MA,LPBK & MT.
However, any remaining client and trunk ports can be in any other service state. For SONET or ANSI cards
in a trunk-side facility loopback, the trunk port service state is OOS-MA,LPBK & MT and the remaining
client and trunk ports can be in any other service state.
With a client-side SDH or ESTI facility loopback, the client port is in the Locked-enabled,maintenance &
loopback service state. However, the remaining client and trunk ports can be in any other service state. For
MXP and TXP cards in a SDH or ETSI trunk-side facility loopback, the trunk port is in the
