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.

6.

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.

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.

Remove the b-pnc SN carrier. 

10.

Disable duplication.
