This bulletin describes how to upgrade the DK424 to a DK424i system. It also lists the upgrade paths for
various DK424 processors, provides system capacity and line considerations, along with reconfiguration
examples and blank configuration worksheets.

Upgrade Considerations

Upgrade Paths – The following is a list of possible DK424 to DK424i upgrade paths:
o RCTU A processors (R1~4.x) >> B1, B2, B3, B5 processors
o RCTU B processors (R1~4.x) >> B2, B3, B5 processors
o RCTUC/D processors (R1~4.x) >> B3 & B5 processors
o RCTU E/F processors (R3~4.x) >> B5 processors
Note For a specific list of all processors, see Page 6 of this bulletin.
System Capacity Verification – Make sure the DK424i system you are upgrading to provides enough
PCB slots, station ports, and CO lines to match the existing DK424 system (see tables below).
