3 Configuring SDH 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.

The physical topology of the network must be created.
The NEs, boards, and fibers must be created on the U2000.
The created protection subnet must be consistent with the actual network topology. For
details about how to create the protection subnet, see
Ring.
You must be familiar with the information about
Allocation.
