NTP-008
Provision STS-1/STS-3 Non-Preemptible Protection
Access (NPPA)
DO ITEMS BELOW IN ORDER LISTED . . . . . . . . FOR DETAILS, GO TO
1. Overview: Normally, this feature will be provisioned via TIRKS. However, it
can also be provisioned from the CIT. This NTP describes the steps that must
be performed in order to add/delete/change NPPA traffic.
!
CAUTION:
Each add/delete/change will affect the same timeslot in every node of the
FT-2000 ring. An add/delete/change need only be entered at a single
node. To delete or change an NPPA assignment, you should make all
changes at the node where that assignment was first made.
!
CAUTION:
When a protection tributary is selected for non-preemptible protection
access, the corresponding STS-3 tributary of service capacity at every
node of the ring becomes unprotected.
NOTE:
Although Release 7.1.0 only provides NPPA at the STS-3 level, it still
requires STS-1 capable (B-5-optics) circuit packs. Release 7.2
provides NPPA at both STS-3 and STS-1 levels (B5-optics are still
required).
If required, connect the craft interface terminal
(CIT) to the FT-2000 network element and con-
dition it.

2. Establish a login to a node. (To remotely establish a
login, refer to DLP-524.)

3. At the CIT, select the
CONFIGURATION-Retrieve-Protection STS3
or (STS1) command and execute to retrieve current
values of the local protection access state variables
for each tributary.
