About This Chapter
This topic uses an example to describe how to configure SDH services on the U2000.
3.1 Basic Concepts
The following basic concepts help you understand and configure the relevant SDH services
correctly.
3.2 Configuring Services on the Non-Protection Chain
Configure the protection subnet and the services on the non-protection chain separately. It is
recommended that you configure the protection subnet before configuring the services on the
non-protection chain.
3.3 Configuring Services on the Non-Protection Ring
Configure the protection subnet and the services on the non-protection ring separately. It is
recommended that you configure the protection subnet before configuring services on the non-
protection ring.
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.
3.5 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.
3.6 Configuring Two-Fiber Unidirectional MSP Services
The two-fiber unidirectional MSP services can provide network level protection for the services
on NEs on the MSP ring. On the U2000, you can add all the NEs on the MSP ring into the
protection subnet to create a two-fiber unidirectional MSP ring.
3.7 Configuring the Two-Fiber Bidirectional MSP Services
To configure the two-fiber bidirectional MSP services, you need to create the MSP subnet
protection and MSP services separately. There is no requirement for the configuration sequence.
