Subtending Rings
Step 9
Go to the network view to view the subtending ring.
Procedure: Subtend a BLSR from a UPSR
This procedure requires an established UPSR and one UPSR node with OC-N cards and fibers to connect
to the BLSR. The procedure also assumes you can set up a BLSR. (For BLSR setup procedures, see the
“Setting Up BLSRs” section on page 5-7
.)
Step 1
In the node that will subtend the BLSR (Node 3 in the
example), install the OC-N cards that
will serve as the BLSR trunk cards (in
, Node 3, Slots 3 and 4).
Step 2
Attach fibers from these cards to the BLSR trunk cards on the BLSR nodes. In
, Slot 3/Node
3 connects to Slot 4/Node 5, and Slot 4 connects to Slot 3/Node 6.
Step 3
From the node view, click the
Provisioning > Sonet DCC
tabs.
Step 4
Click
Create
.
Step 5
In the Create SDCC Terminations dialog box, click the slot and port that will carry the BLSR.
Step 6
Click
OK
.
Step 7
The selected slots/ports are displayed under SDCC Terminations.
Step 8
Put the ports that you will use for the BLSR in service:
a.
In the node view, double-click the BLSR trunk card.
b.
Select the
Provisioning > Line
tabs. Under Status, choose
In Service
.
c.
Click
Apply
.
d.
Repeat steps a – c for the second BLSR trunk card.
Step 9
Use the
“Provision the BLSR” procedure on page 5-9
to configure the BLSR.
Step 10
Follow Steps 1– 8 for the other nodes that will be in the BLSR.
Step 11
Go to the network view to see the subtending ring.
The ONS 15327 can support two BLSRs on the same node. This capability allows you to deploy an ONS
15327 in applications requiring SONET DCSs (digital cross connect systems) or multiple SONET
ADMs (add/drop multiplexers).
shows two BLSRs shared by one ONS 15327. Ring 1 runs on Nodes 1, 2, 3, and 4. Ring 2
runs on Nodes 4, 5, 6, and 7. Two BLSR rings, Ring 1 and Ring 2, are provisioned on Node 4. Ring 1
uses cards in Slots 1and 2, and Ring 2 uses cards in Slots 3 and 4.
Note
Although different node IDs are used for the two BLSRs shown in
, nodes in different
BLSRs can use the same node ID.
