Upgrading Strata DK Systems to DK424 Release 4.0
Program Changes Before/After Release 4.0 Upgrade
The following examples show the type of programs and data that must change when upgrading
from DK14/DK16e/DK40 Release 1 and DK280/DK424 Release 1~Release 3 to DK424
Release 4.0. These program changes are required to make the Strata DK operate the same after
the upgrade as it did before; thus making the upgrade transparent to the end user. The changes
apply to all DK424 Release 4.0, RCTU processors: RCTUA, RCTUB, RCTUBA/BB,
RCTUC/D, and RCTUE/F.
Basically, any program that has station ports as data needs to change if the station port
numbers are higher than the pre-upgrade DID/Tie line port numbers. The examples shown
here represent the
types
of DK programs that require changes when upgrading to Release 4.0.
They are not meant to show all programs since the principles of program changes are the same
for each program type.
The program examples show required programming changes (when upgrading to a DK424
Release 4.0 and above processor) can be complex when a system has DID and Tie lines.
The following examples show the program changes required when upgrading RCTUE3/F3 to
RCTUE3/F4. The DKAdmin Cabinet Drawing and System/Station Administration Screen for
this example are provided in Figures 33~34.
Programs 01 and 02
These programs show the relationship between physical and logical ports. When upgrading to
Release 4.0, these relationships remain the same unless ports have been swapped prior to the
upgrade. If the swapped port numbers shift during the upgrade, they must be renumbered in
Programs 01 and 02. If the swapped ports do not shift during the upgrade, they remain the
same after the upgrade.
In this system configuration, ports 013 and 017 are swapped prior to the upgrade (see Figure
33). After the upgrade, port 013 shifts to 009 and 017 shifts to 013 (see Figure C-4), therefore
after the upgrade port 009 is swapped with port 013. Notice that before and after the upgrade,
the Play Room telephone is on the second PDKU circuit in slot 14 and to call the Play Room
Telephone you must dial 117 - making the upgrade transparent to the end user.
Program 03
There is no change to the data in this program when upgrading to Release 4.0; however the
RDDU DID lines are not allocated ports after the upgrade (see Figures 31 and 32).
Program 04
Data in this program must be changed to adjust for port shifting caused by the RDDU DID line
PCB in slot 13 (see Figures 33 and 34):
