Cisco ONS 15454 Procedure Guide, R5.0
December 2004
Chapter 13 Convert Network Configurations
NTP-A155 Convert a 1+1 Point-to-Point or a Linear ADM to a Two-Fiber BLSR Manually
Note Optical transmit and receive levels should be in their acceptable range as shown in Table 2-3 on
page 2-15.
Caution Traffic is not protected during this procedure.
Step 1 Complete the “DLP-A60 Log into CTC” task on page 17-66 at one of the nodes that you want to convert
from a point-to-point or ADM to a BLSR. If you are already logged in, continue with Step 2.
Step 2 According to local site practice, complete the “NTP-A108 Back Up the Database” procedure on
page 15-4 for each node in the configuration.
Step 3 Complete the “DLP-A298 Check the Network for Alarms and Conditions” task on page 19-63.
Step 4 On the network map, right-click a span adjacent to the node you are logged into. A shortcut menu
appears.
Step 5 From the shortcut menu, click Circuits. The Circuits on Span window appears.
Step 6 Verify that the total number of active STS circuits does not exceed 50 percent of the span bandwidth. In
the Circuits column there is a block titled “Unused.” This number should exceed 50 percent of the span
bandwidth.
Note If the span is an OC-48, no more than 24 STSs can be provisioned on the span. If the span is an
OC-192, no more than 96 STSs can be provisioned on the span. If the span is an OC-12, no more
than 6 STSs can be provisioned on the span.
Caution If the upper STSs are in use, this procedure cannot be completed. Bandwidth must be 50 percent
unassigned to convert to a BLSR. Refer to local procedures for relocating circuits if these requirements
are not met.
Step 7 Repeat Steps 4 through 6 for each node in the point-to-point or linear ADM that you will convert to a
BLSR. When all nodes comply with Step 6, proceed to the next step.
Step 8 For every node in the point-to-point or linear ADM network that you want to convert to a BLSR,
complete the following tasks:
a. Complete the “DLP-A189 Verify that a 1+1 Working Slot is Active” task on page 18-60 for every
1+1 protection group that supports a span in the point-to-point or linear ADM network.
b. Complete the “DLP-A155 Delete a Protection Group” task on page 18-23 at each port that supports
the point-to-point or linear ADM span.
c. Complete the “DLP-A214 Change the Service State for a Port” task on page 19-9 to put the protect
ports out of service at each node that supports the point-to-point or linear ADM span.
Prerequisite Procedures NTP-A124 Provision a Point-to-Point Network, page 5-3 or
NTP-A38 Provision a Linear ADM Network, page 5-6
