l
Non-loopback: It is the normal state. When
the equipment runs normally, set this
parameter to non-loopback.
l
Inloop: The loop is performed toward the
local NE.
l
Outloop: The loop is performed toward the
opposite NE. Inloop and outloop of an
optical interface affect services. They are
used to locate faults.

l
Non-loopback: It is the normal state. When
the equipment runs normally, set this
parameter to non-loopback.
l
Inloop: When input service signals reach
the tributary board of the target NE, the
signals revert to the original trail. This
function is used to locate faults of each
service path.
l
Outloop: When input service signals reach
the tributary board through the input port
of the local NE, the signals are looped back
directly to the service output end.
Service
Load
Indication
l
Non-loaded: The service path does not
process the services that are carried, to
suppress alarms in non-loaded service
paths.
l
Load: The service path processes the
services that are carried. In the case of a
tributary board that has services, set this
parameter to
Load
.
Step 2
Change the values of the board parameters according to service planning and actual board
configurations. For details, see
