DS1C-BD (DS1 Converter Circuit Pack)
a Switch Node Interface, Switch Node Clock, Expansion Interface or
DS1 Converter circuit pack on an unduplicated system disrupts service. The
service effect can range from outage of a single PN to outage of the entire
system.
DS1 Converter complex must consist of two TN574 boards or two TN1654
boards. A TN574 cot be combined with a TN1654 in the same DS1 converter
complex.
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 remove fiber-link fiber#
Remove the TN574 DS1 converter
circuit packs from the system.
Replace the TN574 Y-cables with
TN1654 Y-cables.
Replace the removed TN574 DS1
converter circuit packs with TN1654
DS1 converter circuit packs. Prior to
installing the TN1654 boards, review
the prior section, TN1654 Board
Configuration Switch Settings.
If a TN1654 DS1 converter board is
connected to an SNI board, upgrade
the SNI to a TN573B or greater.
Fiber# represents the fiber-link number associated
with the TN574 DS1 converter complex that is being
upgraded to a TN1654 DS1 converter complex.
Wait for the circuit packs to reset Red and green LEDs will light and then go out.
