CAUTION:
Both TGS/TG3 circuit packs must be installed before
performing this procedure. During this procedure,
downloading TARP Release 13 or 15 software to a shelf
running OC-3 Release 7.x requires you to remove the
TGS/TG3
circuit pack in TIMING slot 1 in order to “force” the
system to run the new software. If both TGS/TG3 circuit
packs are not installed, removal of the only TGS/TG3 circuit
pack will cause service interruption.
NOTE:
BBF4 TG3 circuit packs cannot be mixed with
BBF2/BBF2B/BBF2C TGS circuit packs in the same
DDM-2000 OC-3 shelf.
NOTE:
If upgrading from a Release 7.1 system to a TARP Release
13 or 15 system, after the first shelf is upgraded, single
ended operations will not be available and major alarms
(section DCC channel failed) will exist until all shelves are
upgraded.
NOTE:
This procedure will not affect transmission when properly
performed.
Before performing this procedure on an in-service system, ensure
that both TGS/TG3 circuit packs are installed in the shelf and use
the
switch-sync:s=circuitpack,pri=manual
command to
switch to the protection TGS/TG3 circuit pack in TIMING slot 2, if
not already ACTIVE. Use
rtrv-sync:
command to verify that
the protection TGS/TG3 circuit pack is ACTIVE.
4. From system records, work orders, or the retrieve [RTRV-( )]
commands, retrieve all parameters that might have been set using
the SET commands [DLP-512]. See the Commands and Reports
section of this manual for a description of the
rtrv-( )
commands. Note all the parameters that are set using the
set-ne:
and
set-fecom:
commands. These parameters may
have to be reset when the controllers are replaced and the new
software is installed.
