The PDKU provides eight ports (circuits) for digital
telephones (with or without RPCI-DI, integrated data
interface units and add-on modules), a digital door
control unit (DDCB), stand-alone data
interface units (PDIU-DS), and
a
digital direct Station
selection console
(DDSS). There are
two
versions
of
the PDKU: the P D K U I and the
These
versions are identical, except for the following
distinctions:
The original PDKU version, the
cannot
support Data Interface Units
on Circuit 8.
The later version
can support

each of its circuits.
PDKUI can only be installed in slots
