NTP- D40 Provision MS-SPRing Nodes

Step 2
Log into an ONS 15454 SDH that you want to configure in an MS-SPRing. See the “DLP-D60 Log into
CTC” task on page 17-49. If you are already logged in, continue with Step 3.
Step 3 Complete the “DLP-D363 Provision Regenerator-Section DCC Terminations” task on page 20-68.
Provision the two ports/cards that will serve as the MS-SPRing ports at the node. For four-fiber
MS-SPRings, provision the DCC terminations on the STM-N cards that will carry the working traffic,
but do not provision DCCs on the protect cards.
Note If an ONS 15454 SDH is not connected to a corporate LAN, DCC provisioning must be
performed through a direct (craft) connection to the node. Remote provisioning is possible only
after all nodes in the network have DCCs provisioned to Unlocked-enabled STM-N ports.
Step 4 For four-fiber MS-SPRings, complete the “DLP-D214 Change the Service State for a Port” task on
page 19-10 to put the protect STM-N cards/ports in the Unlocked-enabled service state.
Step 5 Repeat Steps 2 through 4 at each node that will be in the MS-SPRing. Verify that the EOC (DCC
Termination Failure) and LOS (Loss of Signal) are cleared after DCCs are provisioned on all nodes in
the ring.
Step 6 If an MS-SPRing span passes through third-party equipment that cannot transparently transport the K3
byte, complete the “DLP-D89 Remap the K3 Byte” task on page 17-83. This task is not necessary for
most users.
Step 7 As needed, complete the “DLP-D81 Provision a Proxy Tunnel” task on page 17-73.
Step 8 As needed, complete the “DLP-D90 Provision a Firewall Tunnel” task on page 17-83.
Step 9 As needed, complete the “DLP-D40 Create a Provisionable Patchcord” task on page 17-31.
