3.7.2 Signal Flow and Timeslot Allocation

To configure the two-fiber bidirectional MSP service on a ring network, configure the services
that need to be added to the ring network on the source NE, to pass through the intermediate
nodes, and to be dropped from the sink NE, if the MSP protection subnet is already created. In
the case of the ring network, more than one route is available from the source NE to the sink
NE. In actual application scenarios, not all the routes need to be configured. Hence, you need
to properly plan and configure the service directions and timeslots before the configuration.
Figure 3-12
services are configured so that the services enter the ring network from NE1, pass through NE2,
and then are dropped on the sink NE (NE3).
