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
.
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
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
through
for each node in the point-to-point or linear ADM that you will convert to a
BLSR. When all nodes comply with
, 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.
