PNCs have three different reliability configurat ions (one for each system reliability
configuration) as follows:
Simplex PNC
For Simplex PNC, PNC Duplication is disabled on the System-Parameters
Customer-Options form and Op eration of Duplication is d isabled 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 Op eration of Duplication is enab led on the
Duplication-Related System-Parameters form. When PNC Duplication is enab led
on the System-Parameters Customer-Options form, the following ad ministration
forms change:
■Cabinet form — Additional field s appear to allow ad ministration of switch
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 — Additional fields ap pear to allow administration of fib er
links on the B-PNC side of the CSS. If an endpoint on the A-PNC side is
administered as an SNI, its correspond ing endpoint on the B-PNC side is
determined (if switch nodes are paired in the c abinet form prior to this
administration) and disp layed. However, administration o f the duplicate
B-PNC link is not enforced until dup lication is in full operation.
■Duplication-Related System-Parameters form — An ad ditional field
appears to enable op eration of PNC duplication.
