NTP-D318 Convert an Unprotected Point-to-Point or Linear ADM
to a Two-Fiber MS-SPRing Automatically
Note Before beginning this procedure, you should have a unique ring name to identify the new MS-SPRing
and a unique node ID number for each node on the ring.
Note Before beginning this procedure, optical transmit and receive levels should be in their acceptable range
as shown in Table 2-4 on page 2-17.
Note If overhead circuits exist on the network, an in-service topology upgrade is service affecting. The
overhead circuits will drop traffic and have a status of PARTIAL after the upgrade is complete.
Step 1 Complete the “DLP-D60 Log into CTC” task on page 17-49 at a node on the point-to-point or linear
ADM. If you are already logged in, continue with Step 2.
Step 2 Complete the “DLP-D298 Check the Network for Alarms and Conditions” task on page 19-83.
Step 3 Complete the “DLP-D155 Delete a Protection Group” task on page 18-47 at the nodes that support the
point-to-point or linear ADM span.
Step 4 Complete the “DLP-D363 Provision Regenerator-Section DCC Terminations” task on page 20-68 at the
nodes that support the point-to-point or linear ADM span. (Alternatively, if additional bandwidth is
needed for CTC management, complete the “DLP-D364 Provision Multiplex-Section DCC
Terminations” task on page 20-71.) Provision the slot in each node that is not already in the RS-DCC
Terminations list.
Step 5 In the Tools menu, choose Topology Upgrade > Convert SNCP to MS-SPRing.
Step 6 In the Topology Conversion dialog box, set the MS-SPRing properties:
• Ring Type—(Display only) The default is two-fiber.
• Speed—Choose the MS-SPRing ring speed: STM-1, STM-16, or STM-64. The speed must match
the OC-N speed of the MS-SPRing trunk (span) cards.
Note If you are creating an STM-1 MS-SPRing and will eventually upgrade it to STM-16 or
STM-64, use the single-port STM-1 cards (OC12 IR/STM4 SH 1310, OC12 LR/STM4 SH
1310, or OC12 LR/STM4 LH 1550).
Purpose This procedure converts an unprotected point-to-point or linear ADM to
a two-fiber multiplex section-shared protection ring (MS-SPRing)
without disrupting traffic.
