3.2.2 Signal Flow and Timeslot Allocation
To configure services on the non-protection chain, you need to plan the traffic direction and
timeslot allocation for the services on the non-protection chain.
shows the signal flow and timeslot allocation. In this example, five E1 services are
added to or dropped from NE1 and NE2.

3.2.3 Per-NE Configuration Procedure
The configuration of services on the non-protection chain is not related to the configuration of
the protection subnet. To configure the services on the non-protection chain, configure the SDH
services from the tributary board to the line board on the source and sink NEs if the protection
subnet is already created.
Prerequisite
l
The physical topology of the network must be created.
l
The NEs, boards, and fibers must be created on the U2000.
l
The created protection subnet must be consistent with the actual network topology. For
details about how to create the protection subnet, see
2.6.1 Configuring a Non-Protection
l
You must be familiar with the information about
