Enter change system-parameters
duplication. Change the Enable
Operation of PNC Duplication? field
to n.
Disable PNC duplication.
Enter list fiber-link Determine the fiber-link number that the
four TN574 circuit pack s to be upgrad ed
are associated with.
Enter busyout fiber-link <fiber #> fiber # represents the fibe r-link number
associated with the TN574 DS1 CONV
Complexes that are being upgraded to
TN1654 DS1 CONV Complexes.
Enter remove fiber-link <fiber #>
Remove the four TN574 DS1 CONV circuit
packs from the system.
Replace the TN574 Y-cables with
appropriate TN1654 Y-cable s.
Replace the removed TN574 DS1 CONV
circuit pack s with TN1654 DS1 CONV circuit
packs. Prior to installing the TN1654 boa rds,
review the prior section,

TN1654 Board

.
If a TN1654 DS1 CONV board is connected
to an SNI board, upgrad e 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 s uffix B.
cabinet # represents the c abinet
associated with a DS1 CONV board. The
appropriate

change circuit-packs

form
needs to be upd ated for all four DS1
CONV boards. Also, if needed, re-add
translations for connected EI boards.
