3 Configuring SDH Services
Description
In this example, Service Type is set to SNCP.
In this example, E1 services are configured.
Hence, Level of the E1 services is set to VC12.
When an NE is in the switching state, the NE is
restored from the switching state to the normal
state some time after the working path is recovered
to normal.
In this example, the cross-connections are
configured in the SNCP receive direction and in
the SNCP transmit direction.
It is recommended that this parameter adopts the
default value.
After the working path is recovered to normal and
the normal state lasts for 600s, the switching
restoration occurs. This parameter is valid only
when the Revertive Mode parameter is set to
Revertive.
In this example, the SL4D board in slot 1 of NE3
is configured as the source line board of the
working service. See Figure
In this example, the working service source uses
the timeslots of VC4-1.
In this example, five E1 services are configured
between NE3 and NE5. Hence, the working
service source occupies VC-12s 1-5.
In this example, the SP3D board in slot 3 of NE3
is configured as the sink line board of the working
service. See Figure 3-16.
