SNCP Traffic Protection

SNCP traffic protection is defined as a 1 + 1 dedicated path protection scheme
where the transmit end is permanently bridged to both the working and
protection of the subnetwork connections (SNC). At the receive end of the
SNC, a protection switch is performed by selecting one of the signals based on
the path status. No 1+1 MSP protocol is required as SNCP is defined as a
unidirectional protection scheme.

Provisioning SNCP connections

The user performs SNCP connection provisioning from the Cross-connect
application in the Configuration main menu of the local craft access terminal.
The user selects the source and destination port interfaces for the SNCP
connection and specifies the appropriate protection requirements for each
end-point of the end-to-end connection.
The working and protection paths of the SNCP connections can be provisioned
on the same slot or on different slots for the STM-1/4 interfaces of the
2x155/622M aggregate and 2x155M tributary circuit packs. The timeslots for
the working and protection paths of the SNCP connections can be different.
When protection is provisioned for the source or destination end-points of the
SNCP connection, the user must also provision the revertive mode and the
WTR Time period when applicable.

Example 1: Working and protection paths on same slot
The user can provision a SNCP connection with the TU12-1-6-1-1-1-1-1
as the working path and the TU12-1-6-2-1-1-1-1 as the protection path.
Example 2: Working and protection paths on different slots
The user can provision a SNCP connection with the TU12-1-4-1-1-1-1-1
as the working path and the TU12-1-5-1-1-1-1-1 as the protection path.
