3.4 Configuring 1+1 Linear MSP Services

In the case of the 1+1 linear multiplex section protection (MSP), services are transmitted on the
working path and protection path at the same time. The sink NE selects the services from the
working path in normal cases, and selects services from the protection path when the working
path becomes faulty.

3.4.1 Networking Diagram

The networking diagram of the point-to-point 1+1 linear MSP services is simple. Two NEs are
connected with two pairs of optical fibers.

3.4.2 Signal Flow and Timeslot Allocation

To configure the 1+1 linear MSP services, you can configure the services that need to be added
to the source NE and dropped from the sink NE if the 1+1 linear MSP is already created.
3.4.3 Per-NE Configuration Process
This topic describes how to configure the 1+1 linear MSP services.
3.4.4 End-to-End Configuration Process
This topic describes how to configure the 11+1 linear MSP services.
