Configuration Example: SNCP Ring Services

Configuration Example: SNCP Ring Services

When compared to the MSP ring service, the SNCP service has the special physical path as the protection path. In addition, the SNCP service is dually fed and selectively received. In SNCP service configuration, you do not need to respectively create the protection subnet and service. For service configuration, however, you need to respectively configure the working service and protection service.

Networking Diagram

The creation of the SNCP ring network is similar to the MSP ring network. For example, both two topologies are based on two fibers and their services must pass through the intermediate node for transmission from the source NE to the sink NE. The difference is that the SNCP protection and SNCP service can be created on the U2000 at a time.

Figure 6-23 shows an SNCP ring consisting of four NEs. In this example, an NE on the ring network uses the S208 board to transmit SDH services.

Service Planning on a Per-NE Basis

This topic describes service planning on a per-NE basis.

Signal flows and timeslot allocation

Figure 6-24 shows service signal flows and timeslot allocation. In the practical configuration, you can plan the working path and protection path according to requirements. The service capacity is one VC-4.

Service Planning

Table 6-18 Service planning: SDH services on the source NE
Parameter Value in This Example Value Description
Service Type SNCP Set Service Type to SNCP.
Level VC4 In this example, VC-4 services are required. Therefore, set this parameter to VC4.
Revertive Mode Revertive If this parameter is set to Revertive, the NE that is in the switching state releases the switching and services are switched back to the original working path some time after the original working path is restored to normal.
Direction Bidirectional In this example, cross-connections in the SNCP receive direction and the SNCP transmit direction need to be created. Therefore, set this parameter to Bidirectional.
Hold-Off Time(100ms) 0 It is recommended that you set this parameter to the default value.
WTR Time(s) 600 When the time after the original working path is restored to normal reaches the preset WTR time, revertive switching occurs. This parameter is valid only when Revertive Mode is set to Revertive.

Configuration Process (Configuration on a Per-NE Basis)

This topic describes how to create SNCP ring services on a per-NE basis.

Prerequisites

  • The physical topology of the network must be created.
  • The NEs, boards, and fibers must be created on the U2000.
  • An SDH network is a synchronous system and has high requirements on clock synchronization. Therefore, ensure that SDH clocks have been configured before configuring services and features. For details, see "Configuring Clock".

Procedure

  1. Configure virtual port mapping for universal line boards on NE1, NE2, NE3, and NE4 respectively. For details about the procedure, see Configuring Virtual Ports and Mapping Paths by Station.
