Cisco ONS 15454 Procedure Guide, R5.0
August 2005
Chapter 6 Create Circuits and VT Tunnels
NTP-A186 Create a Unidirectional DS-3 Circuit with Multiple Drops
Step 14
If you selected Fully Protected Path in
and the circuit will be routed on a path protection DRI,
check the
Dual Ring Interconnect
check box.
Step 15
Click
Next
. In the Route Review and Edit area, node icons appear so you can route the circuit manually.
The circuit source node is selected. Green arrows pointing from the source node to other network nodes
indicate spans that are available for routing the circuit.
Step 16
Complete the
“DLP-A96 Provision a DS-1 or DS-3 Circuit Route” task on page 17-97
for the DS-3 you
are creating.
Step 17
Click
Finish
. After completing the circuit, the Circuits window appears.
Step 18
In the Circuits window, click the circuit that you want to route to multiple drops. The Delete, Edit, and
Search radio buttons become active.
Step 19
Click
Edit
. The Edit Circuit window appears with the General tab selected. All nodes in the DCC
network appear on the network map. Circuit source and destination information appears under the source
and destination nodes. To see a detailed view of the circuit, click
Show Detailed Map
. You can rearrange
the node icons by selecting the node with the left mouse button while simultaneously pressing
Ctrl
, then
dragging the icon to the new location.
Step 20
In the Edit Circuit dialog box, click the
Drops
tab. A list of existing drops appears.
Step 21
Click
Create
.
Step 22
In the Define New Drop dialog box, define the new drop:
a.
Node—Choose the target node for the circuit drop.
b.
Slot—Choose the target card and slot.
c.
Port, STS—Choose the port and/or STS from the Port and STS drop-down lists. The card selected
in Step b determines whether port, STS, or both appear. See
for a list of
options.
d.
The routing preferences for the new drop match those of the original circuit. However, if the
following options are available, you can modify them:
•
If the original circuit was routed on a protected path protection path, you can change the nodal
diversity options: Nodal Diversity Required, Nodal Diversity Desired, or Link Diversity Only.
See
for option descriptions.
•
If the original circuit was not routed on a protected path, the Protection Channel Access option
is available. See
for a description of the PCA option.
e.
If you want to change the circuit state, choose the circuit state from the Target Circuit Admin State
drop-down list. The state chosen applies to the entire circuit.
f.
Check
Apply to drop ports
if you want to apply the state chosen in the Target Circuit Admin State
to the circuit source and destination drops. For the requirements necessary to apply a service state
to drop ports, refer to the
Cisco ONS 15454 Reference Manual
.
g.
Click
Finish
. The new drop appears in the Drops list.
Step 23
If you need to create additional drops for the circuit, repeat Steps
and
to create the additional drops.
Step 24
Click
Close
. The Circuits window appears.
Step 25
Verify that the new drops appear in the Destination column for the circuit you edited. If they do not
appear, repeat Steps
through
, making sure all options are provisioned correctly.
Step 26
Complete the
“NTP-A135 Test Electrical Circuits” procedure on page 6-36
. Skip this step if you built a
test circuit.
