PDKU2 Hardware Options
PDKU2 does not have to be configured for any option. Refer to Chapter 5 – Station
Apparatus for instructions on how to connect digital telephones, DDCBs, and DDSS consoles
to the PDKU2, as well as how to upgrade digital telephones with these options: an Integrated
Data Interface Unit (RPCI-DI), a Speaker Off-hook Call Announce upgrade (DVSU), and a
Headset/Loud Ringing Bell Interface (HHEU).
There are no controls or indicators on the PDKU (Figure 3-1).
PDKU2 Installation
1. Insert the PDKU2 (component side facing right) into the appropriate slot, and apply
firm, even pressure to ensure proper mating of connectors. (For DK40, PDKU2 must be
installed per tables in Chapter 1 – DK40 Configuration.)
2. After installing the PDKU, gently pull the PCB outward. If the connectors are properly
mated, a slight resistance is felt.
3. Ensure that the Ferrite core supplied is fitted to the Amphenol cable as close the
Expansion KSU as is possible.
