3.5 Configuring 1:1 Linear MSP Services
In the case of the 1:1 linear MSP, services are transmitted on the working path and the sink NE
receives the services from the working path in normal cases. When the working path becomes
faulty, the services are switched to the protection path for transmission and the sink NE receives
the services from the protection path.
3.5.2 Signal Flow and Timeslot Allocation
3.5.3 Per-NE Configuration Process
This topic describes how to configure the 1:1 linear MSP services.
3.5.4 End-to-End Configuration Process
This topic describes how to configure 1:1 linear MSP services in an end-to-end manner.
3.5.1 Networking Diagram
The networking diagram of the point-to-point 1:1 linear LSP services is simple. Two NEs are
connected with two pairs of optical fibers.
, the SP3D boards are used on NE1 and NE2 as tributary boards to add
and drop services, and the SL1D boards are used on NE1 and NE2 as line boards to transmit
SDH services.

3.5.2 Signal Flow and Timeslot Allocation
To configure the 1:1 linear MSP service, 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.
, the signal flow and timeslot allocation are as follows:
