What is ODUk SNCP?
THe ODUk SNCP protection protects services on the line boards and on the units physically located behind the line boards, Cross-Connections on the electrical layer are used to implement dual feeding and selective receiving, and the protection switching is tiggered by OTN overhead alarms, The CRS Granularity is ODUk (K= …
How does SNCP work?
SNCP is a per path protection. It follows the principle of Congruent Sending Selective Receive, i.e., Signal is sent on both paths but received only where the Signal Strength is best. SNCP is a network protection mechanism for SDH networks providing path protection (end-to-end protection).
What is SNC I in OTN?
SNC/I means inherent monitoring and protects services carried over ODUk links (for example,…
Which type of protection is supported in OTN?
Protection schemes considered in this Recommendation are: – ODUk subnetwork connection protection with inherent monitoring (1+1, 1:n); – ODUk subnetwork connection protection with non-intrusive monitoring (1+1); – ODUk subnetwork connection protection with sublayer monitoring (1+1, 1:n).
