7 DIGITAL TELEPHONE INTERFACE
UNIT (PDKU)
7.00 General
7.01 The Digital Telephone Interface Unit (PDKU)
provides eight ports/circuits for digital telephones
and it can only be installed in the Expansion Unit.
The PDKU can also support Integrated Data Inter-
face Units (PDIU-DIs/PDIU-DI2s), Stand-alone Data
Interface Units (PDIU-DSs), a Digital Door Phone/
Lock Control Unit (DDCB), a Digital Direct Station
Selection Console (DDSS), and Add-on Modules
(ADMs). The DDSS console, DDCB, and PDIU-
DSs are wired directly to the PDKU and require no
additional hardware, but do require their own dedi-
cated ports/circuits. The PDIU-DI/PDIU-DI2 or the
ADM shares with its accompanying digital tele-
