DS1 CONV-BD
Removing Fiber Connectivity to an PN
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.
NOTE:
The procedure below is generic in its scope. Check the customer's switch
configuration for EI/SNI structures.
!
WARNING:
Do not power down a Switch Node carrier to replace a circuit pack.
!
WARNING:
In 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 DS1Converter complex consists of two TN574 or TN1654
circuit packs.

Description
Verify that the A-side is active.
a. If the B-PNC is active, enter reset
pnc-interchange and press
b. Then verify that the A-side is active
(status pnc).
Busyout the duplicated switch side.
Disable PNC duplication by changing the
Operation of PNC Duplication?
n.
List administered fiber connections by number.
Record the endpoints (EIs, SNIs, and DS1Cs), and
fiber link numbers that you are removing.
Busyout the fiber link of interest. The fiber link
number (step 4) is n for this command.
Remove the link administration for this link.
