If the services are configured incorrectly and thus need to be deleted, see Deleting SDH Services.

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.

3.3.1 Networking Diagram

You can configure a non-protection ring if the services on the ring need not be protected. In this
case, all the timeslots on the ring can carry services.

3.3.2 Signal Flow and Timeslot Allocation

To configure services on the non-protection ring, you need to plan the traffic direction and
timeslot allocation for the services on the non-protection ring.
3.3.3 Per-NE Configuration Process
The configuration of the services on the non-protection ring is not related to the configuration
of the protection subnet. To configure the services on the non-protection ring, configure the SDH
services from the tributary board to the line board on the source and sink NEs and the pass-
through services on the intermediate NEs if the protection subnet is already created.
3.3.4 End-to-End Configuration Process
The configuration of the services on the non-protection ring is not related to the configuration
of the protection subnet. To configure the services on the non-protection ring, configure the SDH
services from the tributary board to the line board on the source and sink NEs and the pass-
through services on the intermediate NEs if the protection subnet is already created.

You can configure a non-protection ring if the services on the ring need not be protected. In this
case, all the timeslots on the ring can carry services.

the SP3D boards are used on the source NE (NE1) and the sink NE (NE3) as tributary boards
to add and drop services, and the SL1D boards are used as line boards to transmit SDH services.
