Right-click options on TL

On Manage Topological Links page, following right-click options on TL are available:

• Convert Unidirectional TL to Bidirectional TL
• Create Logical TL
• Topology View

Converting Unidirectional TL to Bidirectional TL

In unidirectional mode, traffic moves in one direction only. In bidirectional mode, traffic moves in both the directions on a topological link.

Perform the following steps to convert unidirectional topological link to bidirectional topological link:

1. Go to Topology menu and click Manage TL option. Manage Topological Links page is displayed.
2. Select the desired unidirectional topological link, right-click and select Convert Uni to Bi TL. TLs converted successfully:<TL id> message is displayed. The Unidirectional TL is converted to Bidirectional TL.
3. Click Close to exit the window.

NOTE: Conversion of both Inter EMS TLs and Intra EMS TLs are allowed. The conversion of an offline TL creates only EMS level Topological Links on the EMS database and does not create any trunks on the node whereas in case of an online TL, it is created at node as well as EMS level.

The conversion of a Unidirectional TL to Bidirectional TL feature is supported on STM/OC port TLs and OTN TLs only.

Create Logical TL

Logical TLs creation is supported only on OTN TL. Logical TLs of ODU1 and ODU2 capacity can be created on OTN TL.

Perform the following steps to create logical TLs on the selected OTN TL(s):

1. Go to Topology > Topology Links and click Manage TL option. Manage Topological Links page is displayed.
2. Select the desired TL, right-click and select Create Logical TL option. Create Logical Topological Link window is displayed.

   

3. Select Layer Rate as ODU1 or ODU2 from the drop-down option.
4. To select the time slots, click Select TS button. OTN Channels window is displayed.

   NOTE: Each time slot is of ODU0 capacity. Select two time slots for ODU1 layer rate and eight time slots for ODU2 layer rate.

   

5. Do one of the following:
   • To automatically select the time slots, click Auto button. Go to step 7.
   • To manually select the time slots, click the particular time slot and then click Add Channel. Go to step 7.

   The time slots selected will get displayed under Selected CHANNELS.

6. Click Apply. The selected time slots will be displayed against TimeSlot field on Create Logical TL window.
7. Do one of the following:
   • Select Close on Success check box allowing Create Logical Topological Link window to automatically close after the TL gets created successfully; or
   • Un-check Close on Success check box to re-direct to Create Logical Topological Link window after TL creation.
8. Click Create Logical TL. Successfully Created Logical TL message is displayed.
9. Click OK to close all the windows; or click Close to re-direct to Create Logical Topological Link window.

Topology View

The Topology View option allows few operations like modify user label, add/remove global constraint on TL i.e to include/exclude TL during circuit creation from topology view. Ensure the topology view is launched before performing these operations and perform the following steps:

1. On ManageTL page right click on the desired TL and select Topology View option.
2. Click on the desired option Modify User Label/Add Global Exclude Constraint on TL/Remove Global Exclude Constraint on TL.
3. A pop window appears to open the Topology View page. Open the Topology View page and complete the desired operation by referring to the sections under topic Right-click options supported on TL.
