In the Circuit Routing Preferences area, uncheck Route Automatically.
Step 12
Set the circuit path protection:
Step 13
To route the circuit on a protected path, leave Fully Protected Path checked and continue with
•
Step
To create an unprotected circuit, uncheck Fully Protected Path and continue with
•
If you checked Fully Protected Path, choose one of the following:
Step 14
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 might be node-diverse, but
CTC does not check for node diversity.
Click Next. Beneath Route Review and Edit, node icons appear for you to route the circuit manually.
Step 15
The green arrows pointing from the source node to other network nodes indicate spans that are available
for routing the circuit.
Complete the
Step 16
The following is only seen with DUAL roll mode when both ends of the circuit use the port mentioned
Caution
in this statement. If the termination port is the E1 port, a roll will occur even if a valid signal is not
detected on the Roll To port. The absence of PDI-P downstream for LOS, LOF, and AIS line defects
causes the roll to continue without a valid signal. On the E1 port it is possible to check the Send AIS-V
For E1 AIS check box to properly generate PDI-P downstream for the LOS and LOF AIS line defects.
This check box is selected from the card view, Provisioning > Line tabs. On the E1 port, Send AIS-V for
E1 AIS only works for VC low-order path circuits.
Click Finish. In the Circuits tab, verify that a new circuit appears.
Step 17
This circuit is the Roll To circuit. It is designated with the Roll From circuit name appended with
ROLL**.
Click the Rolls tab. Two new rolls now appear on the Rolls tab. For each pending roll, view the Roll Valid
Step 18
Signal status. When one of the following conditions are met, continue with
If the Roll Valid Signal status is true, a valid signal was found on the new port.
•
If the Roll Valid Signal status is false, a valid signal was not found. Wait until the signal is found
•
before continuing with the next step. To cancel the roll, see the
page
• The roll is a one-way destination roll and the Roll Valid signal status is false. It is not possible to
get a Roll Valid Signal status of true for a one-way destination roll.
Note
• A roll can be forced onto the Roll To Circuit destination without a valid signal by using the Force
Valid Signal button. If you choose Force Valid Signal, traffic on the circuit that is involved in the
roll will be dropped once the roll is completed.
