All Installations

1.When the system reset is finished, enter the status port-network 2 command. The Port Network Status screen appears. Verify that PNC Active is “up” and that the Service State is “in.”

2.A Span LED, on the front of the DS1 Converter circuit pack, must be on for each active facility administered. For example, if Facility A and Facility B are administered, then the top 2 Span LEDs on the circuit pack must be on (yellow). The yellow LEDs are on only if no problems were encountered during the administration of hardware. Span LEDs associated with non-administered facilities (C and D, in this example) should be off.

3.Perform a test call, if desired.

Administer Fiber Links on Duplex Systems

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. All non-duplicated SNIs to SNI fiber links are automatically duplicated.

When PNC Duplication is enabled on the System-Parameters Customer-Options form, the following administration forms change:

■Cabinet Form — Additional fields appear to allow administration 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 Administration Form — Additional fields appear to allow administration of fiber 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 — An additional field appears to enable operation of PNC duplication.

1.Enter the change system-parameters customer-options command. On Page 2 of the form, set the PNC Duplication? field to y. Press Enter.

2.Enter the change system-parameters duplication command. Change the Enable operation of PNC duplication? field to y. Press Enter.

3.Enter the status pnc command. Verify the Duplicated ? field is yes.

4.Enter the list fiber command. All administered fiber connections display.

5.If a previously used fiber link is to be reused, enter the add fiber

< number> command. If this is a new fiber link, enter add fiber next.
