!

A TN573B or later suffix board must be used when connecting a SNI board 
to a TN1654 DS1 Converter board.

Enter list fiber-link

Determine the fiber-link number associated 
with the two TN574 circuit packs to be 
upgraded.

Enter busyout fiber-link <fiber #>

fiber # represents the fiber-link number 
associated with the TN574 DS1 CONV 
Complex that is being upgraded to a TN1654 
DS1 CONV Complex.

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, 

If a TN1654 DS1 CONV board is 
connected to an SNI board, upgrade the 
SNI to a TN573B or greater.

Wait for the circuit packs to reset

Red and green LEDs will light and then go 
out.

Enter change circuit-packs <cabinet 
#>. Update the form to show that 
TN1654 boards are now being used 
instead of TN574 boards. Also update 
the connected SNI, if applicable, to 
suffix B.

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.

Enter add fiber-link <fiber #> to re-add 
the fiber-link using TN1654 DS1 CONV 
circuit packs. See the 

Definity Enterprise 

Communications Server, Release 5, 
Implementation Manual, 555-230-302, 
for details on TN1654 administration.

fiber # represents the fiber-link number 
associated with the TN574 DS1 CONV 
Complex that is being upgraded to a TN1654 
DS1 CONV Complex

Enter test alarms long clear for 
category exp-intf.
