Base/Expansion KSU Compatibility
Expansion Units that are compatible with various Base KSUs are shown in Table 2-26 .
Upgrades
DK40i, (R4.1) can be upgraded to DK40i (R4.3) by changing a ROM chip (order the DK40i, R4.3
Upgrade kit). DK40i, R1 is the only DK that can be upgraded to DK40i, R2. To upgrade DK40i R1
to the DK40, R4.3, the DK40i R4.1 base cabinet must be DKSUBI40A V.1B or higher. If the Base
KSU is DKSUB40IA V.1A, it cannot be upgraded for ACD, T1 or PRI, etc. See FCC label on the
side of the cabinet.
Note
DK40i systems which do not require an upgrade to allow T1, PRI, etc., are identified as
DKSUBI40A V.2A or higher.
The Strata DK16 Base KSU cannot be upgraded to a DK16e, DK40 or DK40i and the DK16
Expansion Cabinet is not compatible with the DK16e, DK40 or DK40i. The Strata DK40i is not a
modification of the DK40, but rather a completely new system.
The DK40i uses the DK40 expansion cabinet. The DK16e can be upgraded to DK40 by changing
a ROM chip, but not to a DK40i. The DK40 base cabinet cannot be upgraded to a DK40i.
DK16/DK16e/DK40/DK40i Component Compatibility
The original DK16 two-loop start CO line and four-digital station interface unit (KCDU1A) is
forward compatible with the DK16e or DK40i.
Most DK16 PCBs are not compatible with the DK40i, including the four-port Standard Station
Interface Unit (KSTU1A), four-circuit DTMF/ABR Tone Detection Receiver Unit (K4RCU1A or
K4RCU2A), and the Auto Attendant feature cartridge (KFCU1A).
Four of the Strata DK40i PCBs are backward compatible with the DK16, DK16e and DK40. They
are: KSTU2A, K4RCU3A, K5RCU and K5RCU2. The DK40i Expansion Cabinet is also
backward compatible with the DK16.
