NTP-A155 Convert a 1+1 Point-to-Point or a Linear ADM to a Two-Fiber BLSR Manually
(Linear ADM only.) Physically remove the protect fibers from all nodes in the linear ADM; for example,

rerouted to connect Node 1/Slot 5 to Node 3/Slot 13.

Step 12
Provision the slot in each node that is not already in the SDCC Terminations list (in the
example, Port 1 of Node 1/Slot 5 and Port 1 of Node 3/Slot 13).
For circuits provisioned on an STS that is now part of the protection bandwidth (STSs 7 to 12 for an
Step 13
OC-12 BLSR, STSs 25 to 48 for an OC-48 BLSR, and STSs 97 to 192 for an OC-192 BLSR), delete and
recreate each circuit:
Complete the
a.
Create the circuit on STSs 1 to 6 for an OC-12 BLSR, STSs 1 to 24 for an OC-48 BLSR, or
b.
STSs 1 to 96 for an OC-192 BLSR on the fiber that served as the protect fiber in the linear ADM.
