3.9.2 Signal Flow and Timeslot Allocation

To configure services on the SNCP ring with a non-protection chain, you need to plan proper
traffic directions for the services on the SNCP ring and the services on the non-protection chain.
In the case of the services on the SNCP ring, allocate timeslots for the source slot of the working
service and timeslots for the source slot of the protection service, when allocating timeslots for
source slots.

Figure 3-16

shows the signal flow of the services on the SNCP ring with a non-protection chain

and the timeslot allocation to the services on the SNCP ring with a non-protection chain . In this
example, five E1 services are configured between NE3 and NE5.

In this example, the traffic direction of the services on the SNCP ring, is configured as follows:

l

Traffic direction of the working service between NE3 and NE4: NE3-NE4

l

Traffic direction of the protection service between NE3 and NE4: NE3-NE2-NE1-NE4

In the actual configuration, you can plan other proper working paths and protection paths
according to the requirement.
