NOTE:
This report lists the state variables of each STS3 tributary for both the
East and West fiber-links. There are three possible state variables. They
are as follows:
a. Preemptible (where a signal fail or signal degrade condition on the
service STS-3 tributaries causes traffic to be automatically switched
to the protection STS-3 tributaries, preemptimg extra traffic).
b. Permanent (where the protection capacity is used, on a permanent
basis, to carry extra traffic; for example, video transport).
c. Temporary (where service traffic is temporarily made unprotected
and the non-preemptible protection capacity is used for
DACS-based network restoration purposes).
4. At the CIT, select the
CONFIGURATION-Enter-Protection-STS3 or
(STS1) command and execute to
add/delete/change the state variable for the desired
tributary.
—
5. Verify that the state variable, for the specified
tributary, has actually been changed per the previous
(Step 4) command. At the CIT, select the
CONFIGURATION-Retrieve-Protection STS3
or (STS1) command and execute to retrieve the
(new) current values.
—
6. Are there additional NPPA changes to be made?
If YES, then continue with Step 2.
If NO, then continue with Step 7.
—
7. The NAPA add/delete/change operation has been
performed. This completes the procedure.
