In the middle node, place the cards in Slots 5 and 13 out of service:
Step 9
a.
Display the first card in card view, then select the Provisioning > Line tabs.
b.
Under Status, select Out of Service. Click Apply.
c.
Repeat Steps a and b for the second card.
Step 10
Delete the equipment records for the cards:
a.
From the View menu, choose Node View.
b.
Right-click the card you just took out of service (e.g. Slot 5) and select Delete Card. (You can also
go to the Inventory tab, select the card, and click Delete.)
c.
Click Yes on the confirmation dialog box.
Repeat (a) through (c) for the second card (e.g. Slot 13).
d.
Save all circuit information:
Step 11
In node view, select the Provisioning > Circuits tab.
a.
Record the circuit information using one of the following procedures:

Step 12
Log into an end node. In node view, click the Provisioning > Sonet DCC tabs.

Step 14
In the SDCC Terminations section, click Create.
Step 15
Highlight the slot that is not already in the SDCC Terminations list (in this example, Port 1 of Slot 5

For circuits running on a BLSR protect STS (STSs 7 – 12 for an OC-12 BLSR, STSs 25 – 48 for an
OC-48 BLSR), delete and recreate the circuit:
Delete the first circuit.

Automatically" and "Fully Protected Path" on the Circuit Creation dialog box so you can manually
route the circuit on the appropriate STSs. See the

c.
Repeat Steps (a) and (b) for each circuit residing on a BLSR protect STS.

OC-N cards in an East/West pattern, it is strongly recommended. If the network ring that is already
passing traffic does not provide the opportunity to connect fiber in this manner, logical provisioning can
be performed to satisfy this requirement.
