A TN573B (or higher-suffixed) board must be used when connecting a SNI
board to a TN1654 DS1 Converter board.
Steps
Enter list fiber-link
Enter busyout fiber-link <fiber #>
Enter remove fiber-link <fiber #>
Remove the TN574 DS1 CONV circuit packs
from the system.
Replace the TN574 Y-cables with
appropriate TN1654 Y-cables.
Replace the removed TN574 DS1 CONV
circuit packs with TN1654 DS1 CONV circuit
packs. Prior to installing the TN1654 boards,
review the prior section, TN1654 Board

fiber # represents the fiber-link number associated
with the TN574 DS1 CONV complex that is being
upgraded to a TN1654 DS1 CONV complex.
Red and green LEDs will light and then go out.
cabinet # represents the cabinet associated with a
DS1 CONV board. The appropriate change
circuit-packs form needs to be updated for both
DS1 CONV boards. Also, if needed, re-add
translations for connected EI boards.
