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.
6. change fiber-link n 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.
7. Physically remove the b-pnc
endpoint circuit packs
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.
8. change circuit-packs Update the translations for the removed circuit
packs using change circuit-packs 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)
9. change cabinet UU Remove the b-pnc SN carrier.
