1.8.2 Configuring SNCP Services
SNCP services can be dual-fed and selectively received and are applicable for protecting services
across subnets. When configuring microwave services on a per-NE basis, you can create SNCP
services to protect services across subnets.
Procedure
Step 1 In the NE Explorer, click an NE and choose Configuration > Cross-Connection
Configuration from the Function Tree.
Step 2 Optional: Click Query to query the cross-connection services from the NE.
Step 3 Click Create SNCP and the Create SNCP Service dialog box is displayed.
Step 4 Set the Service Type, Level, Revertive Mode, Direction, Hold-off Time and WTR time. Set
the Working Service and Protection Service of SNCP.
Step 5 Click OK.

Sample Configuration
In Figure 1-2, NE1, NE2, NE3 and NE4 comprise a unidirectional SNCP ring. The SNCP ring
transmits services by fiber, and the unprotected chain transmits services by microwave.

Four bidirectional E1 services are transmitted between NE1 and NE5. The services use the first
through fourth VC12 timeslots of a tributary board, the first through fourth VC12 timeslots of
an intermediate frequency board, and the first through fourth VC12 timeslots in the first VC4
of a line board.
The E1 services are bidirectional. The service from NE1 to NE5 and the service from NE5 to
NE1 use diverse routes.
l When the network is normal, the service flow between NE1 and NE5 is as follows: E1→
tributary board at NE1→east line board at NE1→west line board at NE2→east line board
at NE2→west line board at NE3→east line board at NE3→west line board at NE4→
intermediate frequency board at NE4→intermediate frequency board at NE5→tributary
board at NE5
l When the network is normal, the service flow between NE5 and NE1 is as follows: E1→
tributary board at NE5→intermediate frequency board at NE5→intermediate frequency
board at NE4→east line board at NE4→west line board at NE1→tributary board at NE1
According to the service flow, you need to perform the configuration as follows:
l Configure add or drop VC12 services for NE1. Configure a bidirectional SNCP service,
and select a west line board as the source of Working Service, an east line board as the
source of Protection Service, and a tributary board as the sink. The source and the sink
timeslots range from 1 to 4.
l Configure pass-through VC12 services for NE2. Configure bidirectional services between
the west and the east line boards. The source and the sink timeslots range from 1 to 4.
l Configure pass-through VC12 services for NE3. Configure bidirectional services between
the west and the east line boards. The source and the sink timeslots range from 1 to 4.
l Configure add or drop VC12 services for NE4. Configure a bidirectional SNCP service,
and select a west line board as the source of Working Service, an east line board as the
source of Protection Service, and an intermediate frequency board as the sink. The source
and the sink timeslots range from 1 to 4.
l Configure add or drop VC12 services for NE5. The source and the sink timeslots of the
bidirectional services between the intermediate frequency board and the tributary board
range from 1 to 4.
