Configuration Process
This topic describes how to configure the services in the 1:1 linear MSP.
Prerequisites
The physical topology of the network must be created.
The NEs, boards, and fibers must be created on the U2000.
Lower order cross-connection resources must meet service configuration requirements. For details on how to query lower order cross-connection resources, see Querying Lower Order Cross-Connection Resources.
The created protection subnet must be consistent with the actual network topology. For details about how to create the protection subnet, see Creating a Linear MS Protection Subnet.
You must be familiar with the contents in Signal Flow and Timeslot Allocation.
Context
CAUTION:
When the lower order resources are insufficient, do as follows:
Combine available lower order resources.
Use a cross-connect board with a higher lower order cross-connect capacity.
Configure VC-4 services.
Procedure
- At NE1, configure SDH services on the source NE.
- Select NE1 from the NE Explorer, and then choose Configuration > SDH Service Configuration from the Function Tree.
- Click Create on the lower-right pane to display the Create SDH Service dialog box. Set the parameters that are required, and then click OK.
| Parameter | Value in This Example | Description |
| Level | VC12 | In this example, E1 services are configured. Hence, Level of the E1 services is set to VC12. |
| Direction | Bidirectional | In this example, services are transmitted and received over the same path. That is, the services are bidirectional services. Hence, Direction of the services is set to Bidirectional. |
| Source Slot | 2-PQ1 | In this example, the PQ1 board in slot 2 is configured as the source tributary board for the bidirectional services from NE1 to NE2. See part1. |
| Source Timeslot Range(e.g.1,3-6) | 1-5 | The total capacity of the service is 5xE1 according to the plan. Hence, Source Timeslot Range(e.g.1,3-6)is set to 1-5. |
| Sink Slot | 11-N2SL16-1(SDH-1) | In this example, the SL16 board in slot 11 is configured as the sink line board. See part 1. |
| Sink VC4 | VC4-1 | In this example, the services require five VC-12s. Sink VC4 is set to VC4-1, because a VC-4 contains 63 VC-12s. |
| Sink Timeslot Range(e.g.1,3-6) | 1-5 | The total capacity of the services is 5xE1 according to the plan. Hence, Sink Timeslot Range(e.g.1,3-6) is set to 1-5. |
- At NE2, configure SDH services on the sink NE.
Click , and select NE2 from the displayed NE Navigator. Click OK.
| Parameter | Value in This Example | Description |
| Level | VC12 | In this example, E1 services are configured. Hence, Level of the E1 services is set to VC12. |
| Direction | Bidirectional | In this example, the services are transmitted and received over the same path. That is, the services are bidirectional services. Hence, Direction of the services is set to Bidirectional. |
| Source Slot | 11-N2SL16-1(SDH-1) | In this example, the SL16 board in slot 11 is configured as the source line board. See part 1. |
| Source VC4 | VC4-1 | In this example, the services require five VC-12s. Source VC4 is set to VC4-1, because a VC-4 contains 63 VC-12s. |
| Source Timeslot Range(e.g.1,3-6) | 1-5 | The total capacity of the services is 5xE1 according to the plan. Hence, Source Timeslot Range(e.g.1,3-6) is set to 1-5. |
| Sink Slot | 2-PQ1 | In this example, the PQ1 board in slot 2 is configured as the sink tributary board for the bidirectional services from NE1 to NE2. See part 1. |
| Sink Timeslot Range(e.g.1,3-6) | 1-5 | The total capacity of the services is 5xE1 according to the plan. Hence, Sink Timeslot Range(e.g.1,3-6) is set to1-5. |
- Check whether the services are configured correctly. For details, see Verifying the Correctness of the Service Configuration.
- Enable the performance monitoring function of the NEs. For details, see Enabling, Disabling and Setting Performance Monitoring of the NE.
- Back up the configuration data of the NEs. For details, see Backing Up the NE Configuration Data to the SCC Board.
Relevant Task
If the services are configured incorrectly and need to be deleted, see Deleting SDH Services.
After SDH services are configured on a per-NE basis, you need to perform an SDH trail search so that you can manage configured services by using the trail management function. For details, see Searching for SDH Services.
