The PDKU does not support door phones or
background music source connection.
l
Each digital telephone requires one port on
the PDKU; the maximum number of digital
telephones per PDKU is eight. Each DDSS
console requires only one port (always cir-
cuit 8), and reduces the maximum number
of
digital telephones by one. Each PDIU-
DS requires one PDKU port, and each
PDIU-DI shares the same port with its
accompanying telephone.
l
Connections from the PDKU to the MDF
are made with 25pair amphenol connec-
tors. Each port normally uses single-pair
wiring. No extra wiring is required for off-
hook call announce.
l
A maximum of four PDKUs can normally
be installed in DK24 to provide thirty-two
digital telephone ports, seven in DK56 to
.
provide fifty-six digital telephone ports, and
twelve in DK96 to provide ninety-six digital
telephone ports.
Electronic Telephone Interface Unit (PEKU):
The PEKU provides eight ports for electronic
telephones. It can be configured for off-hook
call announce by installing an EOCU. It can
also be configured to support a DSS console
and/or door phone control unit (HDCB). One
designated PEKU port can be connected to a
customer-supplied background music source
to feed music to all electronic telephones.
l
Each electronic telephone requires one
port; the maximum num,ber of electronic
telephones per PEKU is eight. The up-
grade for off-hook call announce does not
require a port. Each DSS console requires
two ports and reduces the maximum
