removal of hardware and fiber cable will interrupt service.
DS1C-BD (DS1 Converter Circuit Pack)
Start with the switch carrier most distant from
the 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.
8. change circuit-packs Update the translations for the removed circuit

● 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)
9. change cabinet UU Remove the b-pnc SN carrier.
10. Disable duplication. Obtain a license file to disable PNC
duplication.
Note:
this point in the downgrade procedure, the system is in unduplicated mode and
