MARCH 1993
Stand-alone Data Interface Units (PDIU-DSs).
The PDIU-DI is also used to provide personal
computer access to outside dial-up data ser-
vices and/or bulletin boards.
NOTE:
The PDIU-DI and the PDIU-Dl2 are identical,
except that the PDIU-DI attaches to lOOO-
series Digital Telephones, while the PDIU-
012 attaches to 2000-series Digital Tele-
phones.
PDIU-DS
: Stand-alone Data Interface Unit-Used
for modem pooling, printer sharing, and access to
a host/mainframe computer.
PDKUI
: DigitalTelephone Inter-face Unit (STRATA
DK16 only)-A printed board that can be in-
stalled in the optional Expansion Key Service
Unit to provide the system with eight digital
telephone circuits. In addition to digital tele-
phones, the PDKU can support data interface
units (Stand-alone and Integrated), a digital
DSS console (DDSS), and a digital door phone/
lock control unit (DDCB).
PDKU2:
DigitalTelephone Interface Unit (STRATA
DK16 only)-Provides same function as the
PDKUl, except that the PDKUl can only sup-
port data interface units on Circuits 1 w 7, while
the PDKU2 can support data interface units on
Circuits 1 w 8.
PEKU:
Electronic Telephone Interface Unit
(STRATA DK16 only)-An optional PCB that
provides the system with eight electronic tele-
phone circuits, which can support electronic
telephones, a Background Music source, an
electronic DSS console (HDSS), and an ampli-
fier for two CO line conference calls.
PESU:
Standard/Electronic Interface Unit (STRATA
DK16 only)-A printed circuit board with two
standard telephone circuits and four electronic
telephone circuits that can be installed in the
optional Expansion Key Service Unit. The elec-
tronic telephone circuits can support the same
devices as the PEKU, except for the HDSS
console. The standard telephone circuits can
support the same single-line devices as the
KSTU and the PSTU.
PFT:
Power Failure Transfer Interface-Dedicated
standard telephone interface located on the
motherboard in the DKSUBI 6 (STRATA DK16)
or DKSU8 (STRATA DK8) to provide emergency
service during a system power failure.
PIQU:
Option Interface Unit (STRATA DKl Gorily)-
A printed circuit board that can be installed in the
optional Expansion Key Service Unit to provide
support and/or circuit interface for optional hard-
ware peripherals and upgrades.
PIOUS:
(STRATA DK16 only) The same as the
PIOU, except the PIOUS has one external pag-
ing interface zone, while the PIOU has four.
NOTE:
The system cannot support the PIOU and
PIOUS simultaneously. Only one or the other
can be installed.
PORT:
There are two types of ports: physical and
logical. A physical port is an actual station circuit
location; a logical port is the set of characteris-
tics-features, station intercom number, etc.-
assigned to the physical port. Logical ports are
mobile. They can be moved from one physical
port to another.
PBTC:
A Toshiba-supplied cable used to connect
customer-supplied batteries to the power sup-
ply in the DKSUB for emergency reserve power.
PPTC:
(STRATA DK16 only) A Toshiba-supplied
adapter that is used to connect the modular
SMDR and/or maintenance ports to the DB-25
connector of a printer, terminal, modem or call
accounting machine. The SMDR/Maintenance
(TTY) port is located on the optional QSMU PCB
(STRATA DK8), or PIOU or PIOUS PCB
(STRATA DK16).
PSTUl
: Standard Telephone Interface Unit
(STRATA DK16 only)-A printed circuit board
with a built-in ring generator that can be installed
in the optional Expansion Key Service Unit to
1-4
