SECTION 100-8<strong>16</strong>-201<br />
MARCH 1993<br />
Stand-alone Data Interface Units (PDIU-DSs).<br />
The PDIU-DI is also used to provide personal<br />
computer access to outside dial-up data ser-<br />
vices and/or bulletin boards.<br />
NOTE:<br />
The PDIU-DI and the PDIU-Dl2 are identical,<br />
except that the PDIU-DI attaches to lOOO-<br />
series Digital Telephones, while the PDIU-<br />
012 attaches to 2000-series Digital Tele-<br />
phones.<br />
PDIU-DS : Stand-alone Data Interface Unit-Used<br />
for modem pooling, printer sharing, and access to<br />
a host/mainframe computer.<br />
P<strong>DK</strong>UI : DigitalTelephone Inter-face Unit (STRATA<br />
<strong>DK</strong><strong>16</strong> only)-A printed board that can be in-<br />
stalled in the optional Expansion Key Service<br />
Unit to provide the system with eight digital<br />
telephone circuits. In addition to digital tele-<br />
phones, the P<strong>DK</strong>U can support data interface<br />
units (Stand-alone and Integrated), a digital<br />
DSS console (DDSS), and a digital door phone/<br />
lock control unit (DDCB).<br />
P<strong>DK</strong>U2: DigitalTelephone Interface Unit (STRATA<br />
<strong>DK</strong><strong>16</strong> only)-Provides same function as the<br />
P<strong>DK</strong>Ul, except that the P<strong>DK</strong>Ul can only sup-<br />
port data interface units on Circuits 1 w 7, while<br />
the P<strong>DK</strong>U2 can support data interface units on<br />
Circuits 1 w 8.<br />
PEKU: Electronic Telephone Interface Unit<br />
(STRATA <strong>DK</strong><strong>16</strong> only)-An optional PCB that<br />
provides the system with eight electronic tele-<br />
phone circuits, which can support electronic<br />
telephones, a Background Music source, an<br />
electronic DSS console (HDSS), and an ampli-<br />
fier for two CO line conference calls.<br />
PESU: Standard/Electronic Interface Unit (STRATA<br />
<strong>DK</strong><strong>16</strong> only)-A printed circuit board with two<br />
standard telephone circuits and four electronic<br />
telephone circuits that can be installed in the<br />
optional Expansion Key Service Unit. The elec-<br />
tronic telephone circuits can support the same<br />
devices as the PEKU, except for the HDSS<br />
console. The standard telephone circuits can<br />
1-4<br />
support the same single-line devices as the<br />
KSTU and the PSTU.<br />
PFT: Power Failure Transfer Interface-Dedicated<br />
standard telephone interface located on the<br />
motherboard in the <strong>DK</strong>SUBI 6 (STRATA <strong>DK</strong><strong>16</strong>)<br />
or <strong>DK</strong>SU8 (STRATA <strong>DK</strong>8) to provide emergency<br />
service during a system power failure.<br />
PIQU: Option Interface Unit (STRATA <strong>DK</strong>l Gorily)-<br />
A printed circuit board that can be installed in the<br />
optional Expansion Key Service Unit to provide<br />
support and/or circuit interface for optional hard-<br />
ware peripherals and upgrades.<br />
PIOUS: (STRATA <strong>DK</strong><strong>16</strong> only) The same as the<br />
PIOU, except the PIOUS has one external pag-<br />
ing interface zone, while the PIOU has four.<br />
NOTE:<br />
The system cannot support the PIOU and<br />
PIOUS simultaneously. Only one or the other<br />
can be installed.<br />
PORT: There are two types of ports: physical and<br />
logical. A physical port is an actual station circuit<br />
location; a logical port is the set of characteris-<br />
tics-features, station intercom number, etc.-<br />
assigned to the physical port. Logical ports are<br />
mobile. They can be moved from one physical<br />
port to another.<br />
PBTC: A Toshiba-supplied cable used to connect<br />
customer-supplied batteries to the power sup-<br />
ply in the <strong>DK</strong>SUB for emergency reserve power.<br />
PPTC: (STRATA <strong>DK</strong><strong>16</strong> only) A Toshiba-supplied<br />
adapter that is used to connect the modular<br />
SMDR and/or maintenance ports to the DB-25<br />
connector of a printer, terminal, modem or call<br />
accounting machine. The SMDR/Maintenance<br />
(TTY) port is located on the optional QSMU PCB<br />
(STRATA <strong>DK</strong>8), or PIOU or PIOUS PCB<br />
(STRATA <strong>DK</strong><strong>16</strong>).<br />
PSTUl : Standard Telephone Interface Unit<br />
(STRATA <strong>DK</strong><strong>16</strong> only)-A printed circuit board<br />
with a built-in ring generator that can be installed<br />
in the optional Expansion Key Service Unit to
