Upgrading Strata DK Systems to DK424 Release 4.0
Upgrading Strata DK Systems to
DK424 Release 4.0
C
The following important items must be considered when upgrading the DK14, DK16e, DK40,
DK280, and DK424 Release 1~3 systems to a DK424 Release 4.0.
A new feature in DK424 Release 4.0 is increased station capacity in systems containing Tie
and Direct Inward Dialing (DID) lines. In Release 4.0, the station capacity of systems that
contain Tie/DID lines increases due to Release 4.0 eliminating automatic assignment of station
ports to DID and Tie lines. Tie and DID lines provided by RDDU, RDTU, RPTU, REMU, and
PEMU circuit cards do not use station ports.
This appendix provides instructions and examples of how DKAdmin/DK Backup, Release 4.0
adjusts for station port shifting caused by Tie and/or DID lines when upgrading to DK424,
Release 4.0 software and above. This phenomenon occurs only when upgrading to DK424
Release 4.0 processors in systems that have station PCBs installed in higher numbered slots
than Tie/DID line PCBs.
Table 8
shows the different DK upgrade possibilities using the Release 4.0 version of
DKAdmin/DKBackup. For example, you can upgrade from an RCTUA, R3 to an RCTUBB,
R4; however, you cannot upgrade an RCTUA, R3 to an RCTUD, R1/R2.
