Step 2
Log into an ONS 15454 that you want to configure in a BLSR. See the
. If you are already logged in, continue with Step
.
Step 3
Complete the
“DLP-A377 Provision Section DCC Terminations” task on page 20-61
. Provision the two
ports/cards that will serve as the BLSR ports at the node. For four-fiber BLSRs, provision the DCC
terminations on the OC-N cards that will carry the working traffic, but do not provision DCCs on the
protect cards.
Note
If an ONS 15454 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 IS-NR OC-N ports.
Step 4
For four-fiber BLSRs, complete the
“DLP-A214 Change the Service State for a Port” task on page 19-9
to put the protect OC-N cards/ports in service.
Step 5
Repeat Steps
through
at each node that will be in the BLSR. 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
As needed, complete the
“DLP-A380 Provision a Proxy Tunnel” task on page 20-63
.
Step 7
As needed, complete the
“DLP-A381 Provision a Firewall Tunnel” task on page 20-64
Step 8

“DLP-A367 Create a Provisionable Patchcord” task on page 20-51
Step 9
If a BLSR span passes through third-party equipment that cannot transparently transport the K3 byte,
complete the
“DLP-A89 Remap the K3 Byte” task on page 17-87
