duplicated PNC 2 of 2
Step Command/Step Description
8. Remove the DS1- CONV
hardware.
DS1C-BD (DS1 Converter Circuit Pack)
Remove the 4 TN574 or TN1654 DS1-CONV

The TN1654 and TN574 DS1-CONV boards use
unique “Y” cables that are incompatible with each
other. Reuse these cables only with the proper
circuit pack.
9. Install fiber-optic cable. Add the lightwave transceivers (multimode 9823A
or single-mode 300A) to match the lightguide
fiber. Add these to the EIs and SNIs formerly
connected to the DS1 converter circuit packs.
Connect the lightwave transceivers with
lightguide fiber.
10. Check fiber-optic cable
connections.
Ensure that the fiber-optic cables are securely
connected to the lightwave transceivers that are
attached to the designated circuit packs through
the connections on the back of the cabinet.
11. add fiber-link n Administer the new EI/SNI fiber connection.
12. change system-parameters

13. Enter test alarms long
clear for category exp-intf.
Enable PNC duplication by changing the Enable
Operation of PNC Duplication field to y.
14. Wait 5 minutes. SNI-BD, SNI-PEER, FIBER-LK and EXP-INTF
MOs need time to clear (or enter clear
