Chapter 5 Create Circuits and VT Tunnels
To create an unprotected circuit, uncheck Fully Protected Path and continue with
•
To route the circuit on a BLSR protection channel, if available, uncheck Fully Protected Path,
•
check Protection Channel Access, click Yes on the Warning dialog box, and then continue with
Step
Caution Circuits routed on BLSR protection channels are not protected and are preempted during BLSR
switches.
Step 11 If you selected Fully Protected Path, choose one of the following:
• Nodal Diversity Required—Ensures that the primary and alternate paths within the path protection
portions of the complete circuit path are nodally diverse.
• Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not
possible, CTC creates fiber-diverse paths for the path protection portion of the complete circuit path.
• Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for path
protection portions of the complete circuit path are needed. The paths may be node-diverse, but CTC
does not check for node diversity.
Note
If you selected Fully Protected Path and the circuit will be routed on a path protection dual ring
Step 12
interconnect (DRI), check the Dual Ring Interconnect check box.
Click Next. In the Route Review and Edit area, node icons appear for you to route the circuit manually.
Step 13
The green arrows pointing from the selected node to other network nodes indicate spans that are
available for routing the circuit.
Complete the
Step 14
Click Finish. After completing the circuit, CTC displays the Circuits window.
Step 15
On the Circuits window, click the circuit that you want to route to multiple drops. The Delete, Edit, and
Step 16
Search buttons become active.
Click Edit. The Edit Circuit window appears with the General tab selected. All nodes in the DCC
Step 17
network appear on the network. Circuit source and destination information appears under the source and
destination nodes. To display 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, pressing Ctrl and dragging the icon to
the new location.
On the Edit Circuit dialog box, click the Drops tab. A list of existing drops appears.
Step 18
Click Create.
Step 19
On the Define New Drop dialog box, define the new drop:
Step 20
Node—Choose the target node for the circuit drop.
a.
Slot—Choose the target card and slot.
b.
Port, STS—Choose the port and/or STS from the Port and STS drop-down menus. The choice in
c.
these menus depends on the card selected in Step b. See
March 2003
13.
For manually-routed circuits, CTC checks your manually-provisioned path against the path
diversity option you choose. If the path does not meet the path diversity requirement that is
specified, CTC displays an error message.
