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-DI2 are identical,
except that the PDIU-DI attaches to 1000-
series Digital Telephones, while the PDIU-
DI2 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.
PDKU1: Digital Telephone Interface 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: Digital Telephone Interface Unit (STRATA
DK16 only)—Provides same function as the
PDKU1, except that the PDKU1 can only sup-
port data interface units on Circuits 1 ~ 7, while
the PDKU2 can support data interface units on
Circuits 1 ~ 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 DKSUB16 (STRATA DK16)
or DKSU8 (STRATA DK8) to provide emergency
service during a system power failure.
PIOU: Option Interface Unit (STRATA DK16 only)—
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).
PSTU1: 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
