Chapter 12 Convert Network Configurations
Before You Begin
Step 10
Physically connect the fibers between the point-to-point node and the new node. The fiber connections
should be connected working port to working port and protect port to protect port.
Step 11
On the new node, create a 1+1 protection group for the STM-M cards/ports that will connect to the
neighbor nodes. For 1+1 provisioning procedures, refer to the documentation specific to the device you
are adding.
Step 12
Provision section DCC terminations on the new node’s working STM-M cards/ports as specified in the
documentation for that device. Make sure to set the Port State in the Create RS-DCC Termination dialog
box to
unlocked
.
Note
Data communications channel (DCC) failure alarms appear until you create DCC terminations
in the point-to-point node.
Step 13
From the View menu, choose
Go to Network View
to verify that the newly created linear ADM
configuration is correct. One green line should appear between each linear node.
Step 14
Click the
Alarms
tab and click Synchronize.
a.
Verify that the alarm filter is not on. See the
“DLP-H88 Disable Alarm Filtering” task on
as necessary.
b.
Verify that no unexplained alarms appear on the network. If alarms are present, investigate and
resolve them before continuing. Refer to the
Cisco ONS 15310-MA SDH Troubleshooting Guide
if
necessary.
Step 15
Repeat the procedure to add an additional node to the linear ADM.
Stop. You have completed this procedure.
NTP-H96 Convert an Unprotected Point-to-Point or Linear ADM
to a Path Protection Configuration Automatically
Note
When upgrading VC low-order path tunnels, CTC does not convert the VC low-order path tunnel to path
protection, but instead creates a secondary tunnel for the alternate path. The result is two unprotected
VC low-order path tunnels using alternate paths.
Purpose
This procedure upgrades a point-to-point or linear ADM to a path
protection configuration without disrupting traffic. You can upgrade VC
high-order path, VC low-order path, and VC low-order path tunnel
circuits to path protection configuration. This option is a single circuit
operation.
