Chapter 13 Convert Network Configurations
NTP- D210 Convert an SNCP to a Two-Fiber MS-SPRing Manually
Note
Prior to beginning this procedure, optical transmit and receive levels should be in their acceptable range
as shown in
.
Step 1
Log into an ONS 15454 SDH on the network where you will begin the ring conversion. See the
“DLP-D60 Log into CTC” task on page 17-49
. If you are already logged in, continue with Step 2.
Step 2
Complete the
“DLP-D298 Check the Network for Alarms and Conditions” task on page 19-83
.
Step 3
On the network map, right-click a span adjacent to the node you are logged into. A shortcut menu
appears.
Step 4
From the shortcut menu, click
Circuits
. The Circuits on Span window appears.
Step 5
Verify that the total number of active VC4 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 STM-16, no more than 8 VC4s can be provisioned on the span. If the span is an
STM-64, no more than 32 VC4s can be provisioned on the span. If the span is an STM-4, no
more than 2 VC4s can be provisioned on the span.
Caution
If the first half of the capacity is exceeded, this procedure cannot be completed. Bandwidth must be
50 percent unassigned to convert to MS-SPRing. Refer to your site plan for relocating circuits if these
requirements are not met.
Step 6
Repeat Steps
for each node in the SNCP that you will convert to an MS-SPRing. When all nodes
comply with
, continue with the next step.
Step 7
Save all circuit information:
a.
In network view, click the
Circuits
tab.
b.
Record the circuit information using one of the following options:
•
From the File menu, click
to print the circuits table. See the
.
•
From the File menu, click
Export
and choose the data format: HTML, CSV (comma separated
values), or TSV (tab separated values). Click
OK
and save the file in a temporary directory. See
the
“DLP-D147 Export CTC Data” task on page 18-38
Step 8
Delete the circuits:
Note
This method uses the network view. To delete circuits one at a time from each node, see the
“DLP-D27 Delete Circuits” task on page 17-21
.
a.
In network view, click the
Circuits
tab. All circuits on the ring appear.
b.
With the
Ctrl
key pressed, click each circuit. Each line turns dark blue as it is selected.
c.
After all circuits have been selected, click
Delete
. Allow several minutes for processing; the actual
length of time depends on the number of circuits in the network.
Step 9
Complete the
“NTP-D41 Create the MS-SPRing” procedure on page 5-13
to create the MS-SPRing.
