DK424 Release 4.0 Upgrade Programming Example

–––––––––––––––––––––––––––––––––––––––––––––––––––

The following Release 3.0 to Release 4.0 upgrade example demonstrates some basic 
programming changes automatically performed by DKAdmin due to station port shifting. 
Station port shifting only occurs when station PCBs are in higher numbered slots than Tie and/
or DID lines.

This example does not give you every program change required, nor does it attempt to instruct 
you on how to re-program a system upgraded to Release 4.0, using the programming 
telephone. This is a simple system upgrade; an actual installed systems can be much more 
complex to upgrade.

Figures 31

 shows the DKAdmin cabinet drawing of a DK424 system with an:

♦

RCTUE3/F3 processor

♦

RSIU interface

♦

16 Digital telephones

♦

4 analog DID lines

Notice that the RDDU PCB increments the station ports by four ports.

Figure 32

 shows the same DKAdmin cabinet drawing after upgrading to an RCTUE3/F4 with 

DKAdmin. 

Notice that the telephones connected to the PDKU2 in slot 14 were on ports 012~019 but are 
now on ports 008~015, respectively. This phenomenon requires many programming changes 
to enable the DK system to operate the same as it did prior to the upgrade. DKAdmin/
DK Backup Release 4.0 is designed to make all programming changes automatically to enable 
the upgrade to be transparent to the system operation.
