5. change fiber n
6. Physically remove the b-pnc
endpoint circuit packs
7. change circuit pack
8. change cabinet UUC
9. Disable duplication.
!
CAUTION:
The removal of hardware and fiber cable will interrupt service.
NOTE:
At this point in the downgrade procedure, the system is in unduplicated
mode and is operational. The physical removal of the SN carriers may be
done at a time that is convenient for the customer. The next step in the
downgrade is to follow the normal upgrade procedures from standard to
high reliability.

Description
Change fiber removes the b-pnc endpoints
(EI, DS1Cs, if equipped). n is the number of
the fiber from step 4. Repeat this step for
every fiber from step 4.
Start with the switch carrier most distant
from the media server. Physically remove
EI, SNI, and SNC circuit packs associated
with the b-pnc.
Remove fiber cable not used for b-pnc
carriers. See the following CAUTION.
Update the translations for the removed
circuit packs using the change circuit pack
command for the:
Cabinet with b-pnc SN carrier
— SNIs
— SNCs
— EIs and DS1Cs, if any
Cabinet with b-pnc SN carrier
— DS1Cs from port carrier
Cabinet with b-pnc EIs in every PN
(also DS1Cs, if equipped)
Remove the b-pnc SN carrier.
Obtain a license file to disable PNC
duplication.
