Fiber Link Administration
PNCs have three different reliability configurations (one for each system reliability
configuration) as follows:
System Configuration
Standard Reliability
High Reliability
Critical Reliability
Simplex PNC
For Simplex PNC, PNC Duplication is disabled on the System-Parameters
Customer-Options form and Operation of Duplication is disabled on the
Duplication-Related System-Parameters form.
Administration of PNC Duplication
The PNC Duplication feature is enabled on the System-Parameters
Customer-Options form and Operation of Duplication is enabled on the
Duplication-Related System-Parameters form. When PNC Duplication is enabled
on the System-Parameters Customer-Options form, the following administration
forms change:
Cabinet form
nodes to A-PNC and B-PNC sides of the CSS. The B-PNC is the
duplicated hardware for the A-PNC. Either the A-PNC or the B-PNC can
provide full customized service. B-PNC cannot be used in a simplex PNC
configuration. Pairing of switch nodes is also defined here.
Fiber Link form
links on the B-PNC side of the CSS. If an endpoint on the A-PNC side is
administered as an SNI, its corresponding endpoint on the B-PNC side is
determined (if switch nodes are paired in the cabinet form prior to this
administration) and displayed. However, administration of the duplicate
B-PNC link is not enforced until duplication is in full operation.
Duplication-Related System-Parameters form
appears to enable operation of PNC duplication.
