DLP- F355 Roll Two Cross-Connects from One Optical Circuit to a Second Optical Circuit

DLP-F355 Roll Two Cross-Connects from One Optical Circuit to a Second Optical Circuit

	Purpose	This task reroutes a network path using two optical circuits by allowing
		CTC to select the Roll To path on the second circuit automatically.
	Tools/Equipment	None
	Prerequisite Procedures	DLP-F181 Log into CTC, page 16-34
	Required/As Needed	As needed
	Onsite/Remote	Onsite or remote
	Security Level	Provisioning and higher
Step 1	From the View menu, choose Go To Network View.
Step 2	Click the Circuits tab.
Step 3	Press Ctrl and click the two circuits that you want to use in the roll process.
	The Roll From path will be on one circuit and the Roll To path will be on the other circuit. The circuits
	must have a DISCOVERED status and must be the same size and direction for you to start a roll. The
	planned Roll To circuit must not carry traffic.The first Roll To path must be DCC connected to the source
	node of the Roll To circuit, and the second Roll To path must be DCC connected to the destination node
	of the Roll To circuit.
Step 4	From the Tools menu, choose Circuits > Roll Circuit.
Step 5	In the Roll Attributes area, complete the following:

a.From the Circuit Roll Mode drop-down list, choose Auto to create an automatic roll (required for a 1-way source roll) or Manual to create a manual roll (required for 1-way destination roll).

b.From the Circuit Roll Type drop-down list, choose Dual.

c.In the Roll From Circuit area, click the circuit that contains the Roll From path.

Step 6 Click Next.

Step 7 In the Pivot/Fixed Point 1 window, click the square representing the fixed path of the first cross-connect to be rolled (Figure 18-13 on page 18-58).

This path is a fixed point in the cross-connect involved in the roll process. The path identifier appears in the text box below the graphic image. The path that is not selected contains the Roll From path. The Roll From path is deleted after the roll is completed.

Step 8 Click Next.

Step 9 Complete one of the following:

•If multiple Roll From paths exist, the Select Roll From dialog box appears. Select the path from which you want to roll traffic and click OK (Figure 18-18 on page 18-64).

•If multiple Roll From paths do not exist, continue with Step 10.

The circuit status for the Roll From path changes from DISCOVERED to ROLL PENDING.

Step 10 In the Pivot/Fixed Point 2 window, click the square that represents the fixed path of the second connection to be rolled.

The path that is not selected is the Roll From path. The Roll From path is deleted after the roll is completed. The path identifier appears in the text box below the graphic image.
