Removing Fiber Connectivity to an PN
DS1C-BD (DS1 Converter Circuit Pack)
This procedure covers removing the connectivity to an PN or between SNs. Removing an PN
and its associated carrier and circuit packs can be handled on a board-type basis.
If this system is duplicated, start with step 1; otherwise, start with step 6.

duplicated PNC configurations, one DS1-CONV complex in the fiber-link
serves as the active and the second DS1-CONV complex serves as the standby.
Each DS1 Converter complex consists of two TN574 or TN1654 circuit packs.

Step Command/Step Description
1. status pnc Verify that the A-side is active.
1. If the B-PNC is active, enter
reset pnc-interchange
2. Verify that the A-side is active
(status pnc).
3. busyout pnc standby Busyout the duplicated switch side.
4. change system-parameters
duplication
Disable PNC duplication by setting the
Enable Operation of PNC
Duplication field to n.
5. list fiber-link List administered fiber connections by
number. Record the endpoints (EIs, SNIs,
and DS1Cs), and fiber link numbers that you
are removing.
6. busyout fiber-link n Busyout the fiber link of interest. The fiber link
number (step 4) is n for this command.
7. remove fiber- link n Remove the link administration for this link.
8. change system-parameters

9. Physically remove the a-pnc and
b-pnc fiber endpoint circuit packs
Enable PNC duplication by changing the
Enable Operation of PNC
Duplication field to y.
Physically remove EI, SNI, and DS1C circuit
packs associated with the b-pnc.
