duplicated PNC configurations, one DS1 converter complex in the fiber-link
serves as the active and the second DS1 converter complex serves as the
standby. Each DS1 Converter complex consists of two TN574 boards or two
TN1654 boards. A TN574 cot be combined with a TN1654 in the same DS1
converter complex. It is also required that all four DS1 converter boards and
interconnecting facilities that serve an PN be of the same type. Note, however,
that TN574 and TN1654 boards can coexist within the same system, they just cot
be in the same fiber-link.
two DS1 converter boards, TN1654 and TN574, use unique “Y” cables that
are incompatible with each other.
TN573B (or higher-suffixed) board must be used when connecting a SNI board
to a TN1654 DS1 Converter board.

Steps Comments
Enter status pnc. Verify that the A-PNC is active. If the B-PNC is
active, enter the reset pnc interchange command to
cause the A-PNC to go active.
Enter busyout pnc-standby. Fiber link cot be removed if PNC duplication is
operational. Must busyout the standby PNC first.
Enter change system-parameters

Disable PNC duplication.
Enter list fiber-link. Determine the fiber-link number that the four
TN574 circuit packs to be upgraded are associated
with.
