Network reconfiguration 8-
This chapter contains procedures for adding and deleting a network element
in a Sub Network Connection Protection/Unidirectional Path Switched Ring
(SNCP/UPSR) network.
SNCP/UPSR
SNCP/UPSR is path protection type that is initiated in the path terminating
equipment. In SNCP/UPSR, protection is initiated on a failure in the path. It is
required to create two paths for each circuit, one working and the other
protection. Traffic in the source network element is bridged on both paths, the
working and the protection. The better signal of the two is selected by the
destination network element. SNCP/UPSR is a dedicated protection
mechanism.
If the network element is equipped with two 15G MRO XC circuit packs, then
select STM-4/OC-12, or STM-16/OC-48 for the node capacity of the network
element. If the network element is equipped with two 60G MRO XC circuit
packs, then the rate is STM-64/OC-192.
