GENERAL END USER INFORMATION
The STRATA DK Electronic Digital Key telephone systems
are registered in accordance with the provisions of Part 68 of
the Federal Communications Commission’s Rules and Regu-
lations.
FCC REQUIREMENTS
Means of Connection:
The Federal Communications Com-
mission (FCC) has established rules which permit the
STRATA DK system to be connected directly to the tele-
phone network. Connection points are provided by the
telephone company-connections for this type of cus-
tomer-provided equipment will not be provided on coin
lines. Connections to party lines are subject to state tariffs.
Incidence of Harm:
If the system is malfunctioning, it may
also be disrupting the telephone network. The system
should be disconnected until the problem can be deter-
mined and repaired. If this is not done, the telephone
company may temporarily disconnect service. If possible,
they will notify you in advance, but, if advance notice is not
practical, you will be notified as soon as possible. You will
be informed of your right to file a complaint with the FCC.
Service or Repair:
For service or repair, contact your local
Toshiba telecommunications distributor. To obtain the
nearest Toshiba telecommunications distributor in your
area, call Toshiba America Information Systems, Inc.,
Telecommunication Systems Division in Irvine, CA (714)
583-3700.
Telephone Network Compatibility:
The telephone company
may make changes in its facilities, equipment, operations,
and procedures. If such changes affect the compatibility or
use of the STRATA DK system, the telephone company will
notify you in advance to give you an opportunity to maintain
uninterrupted service.
Notification of Telephone Company:
Before connecting a
STRATA DK system to the telephone network, the tele-
phone company may request the following:
1) Your telephone number.
2) FCC registration number:
l
STRATA DK may be configured as a Key or Hybrid
telephone system. The appropriate configuration for
your system is dependent upon your operation of the
system.
l
If the operation of your system is only manual selec-
tion of outgoing lines, it may be registered as a Key
telephone system.
l
If your operation requires automatic selection of out-
going lines, such as dial access, Least Cost Routing,
Pooled Line Buttons, etc., the system must be regis-
tered-as a Hybrid telephone system. In addition to the
above, certain features (TIE Lines, Off-premises
Stations, etc.) may also require Hybrid telephone
system registration in some areas.
l
If you are unsure of your type of operation and/or the
appropriate FCC registration number, contact your
local Toshiba telecommunications distributor for as-
sistance.

3) Ringer equivalence number: 0.28 (see Table A). The
ringer equivalence number (REN) is useful to determine
the quantity of devices which you may connect to your
telephone line and still have all of those devices ring when
your number is called. In most areas, but not all, the sum
of the RENs of all devices connected to one line should not
exceed five (5.08). To be certain of the number of devices
you may connect to your line, as determined by the REN,
you should contact your local telephone company to ascer-
tain the maximum REN for your calling area.

1 GENERAL
Summary
STRATA DK digital key telephone systems are
advanced key/hybrids that are electrically com-
patible with the public telephone network (loop
start CO lines and E & M TIE lines) and can
function in PBX or Centrex environments.
NOTE:
Every time “CO line” is mentioned hereafter,
the information also applies to Centrex and
PBX lines.
Each system can be configured as key or
hybrid, with separate Federal Communications
Commission registration numbers for each type.
The appropriate configuration for an individual
system depends on its function.
STRATA DK24, DK56, and DK96 models are
very similar in design. Figure 1 illustrates the
impressive range of basic features and options
available on all three systems; Figure 2 shows
the cabinets and their relative sizes. To accom-
modate a wide variety of users’ application and
expansion needs, system cabinet configurations
are extremely flexible.
FIGURE L-STRATA DK24, DK56, and
DK96 CABINETS
The functional difference between models is
primarily one of capacity (see Table A). STRATA
STRATA DK
GENERAL DESCRIPTION
DECEMBER 1990
DK24 can be configured in possible combina-
tions extending from 32 stations and 8 CO lines
to a square system of 16 X- 16.’ STRATA DK56
can be configured in possible combinations
extending from 56 stations and 4 CO lines to 24
stations and 20 CO li:tes. STRATA DK96 combi-
nations extend from 96 stations and 8 CO lines
to 40 stations and 36 CO lines (see Table A).
Toshiba digital telephones are connected to
the system with l-pair cabling. With a 2B+D
ISDN-type digital link, this single pair transmits
and receives simultaneous voice and data along
with control information. Toshiba electronic tele-
phones are connected to the system with 2-pair
cabling, and can access most of the same
advanced features as the digital telephones.
Solid-state digital electronics inside the key serv-
ice unit translate digital signals from the electron-
ic and digital telephone dialpads into either
DTMF tones or rotary dial signals, depending on
the central office’s requirements (see Peripheral
Hardware Descriptions). Many customer-sup-
plied standard telephones and auto attendant/
voice mail devices are also compatible with the
systems, because the systems provide end-to-
end DTMF signaling between digital and elec-
tronic telephones and devices connected to
standard telephone ports.
Technology
STRATA DK digital key telephone systems
apply the following technology:
Pulse Code Modulation: The system is com-
pletely digital. Therefore, talk paths operate
through digital switching, as opposed to ana-
log crosspoints. Analog-to-digital and digital-
to-analog conversion is accomplished by
CODECs on station and CO line PCBs. Pulse
Code Modulation technology allows fully non-
blocking intercom and outside line talk paths.
Stored Program Control: The system uses a
16-bit microprocessor to achieve stored pro-
gram control. System operating software is
stored in read only memory (ROM). The sys-
tem’s individual configuration and custom pro-

grarnming is stored in random access memory
(RAM). RAM
is protected by a lithium battery,
which has at least a six year life span.
Microprocessors: The system’s main micropro-
cessor is a 16-bit 68000-type that operates at
a clock speed of 8 MHz. It is located on the
system’s control board (PCTU). Local micro-
processors are located on all printed circuit
boards. The local microprocessor is an 8-bit
TMP90C840-type that operates at a clock
speed of 10 MHz.
Custom Electronic Circuitry: Use of large scale
integration (LSI) technology enables STRATA
DK circuit design to be simple and efficient.
More circuitry fits onto smaller printed circuit
boards (PCBs) and affords a compact system.
Widespread use of CMOS circuits minimize
the system’s power requirements.
Power Supply: The system uses a switching-
type power supply to generate *5VDC and
-24VDC. Mechanical circuit breakers on the
front panel, which may be reset if necessary,
protect these DC voltages.(See Table B for
General Requirements).
l
The source of the power used is a stan-
dard 117VAC, 15 amp circuit. The power
supply has a built-in battery charger to
maintain customer-supplied batteries
which can be connected as a backup. This
allows full normal system operation for a
number of hours in the event of a primary
power failure. (For more detail, see Table
Q
Maiqtenance and Programming
As a result of large scale integrated circuitry,
STRATA DK
telephone systems have a minimal
number of printed circuit board types. Less time
is spent isolating board failures. This directly
translates to saving time and money.
Hardware maintenance and repair procedures
describe how to quickly and easily locate,
remove, and replace defective modules, with
minimal or no system downtime.
A remote administration -and ma’intenance
option can be added to install and maintain cus-
tomer software, and to test hardware from
remote locations.
On-site maintenance and programming is
accomplished using:
l
The 20-button LCD digital or electronic
telephone designated for programming
and maintenance, always connected to
station port 05. This telephone may be
used as a normal station when not used
for programming.
-or-
* An on-site ASCII terminal connected to an
optional maintenance port.
2 PERIPHERAL
HARDWARE DESCRIPTIONS
A wide variety of peripheral equipment is com-
patible with all three systems (see Figure 1).
Peripherals fall under four different categories:
digital telephones, electronic telephones,
Toshiba-supplied peripherals, or customer-sup-
plied peripherals. This section describes the
Toshiba-supplied equipment. When applicable,
system interface information is included.
Digital Telephonest
There are two digital telephone models avail-
able. The phones are enclosed in a stylish,
impact-resistant case with a charcoal gray matte
finish, and blend easily into any progressive
office environment.
Both digital telephone models and the digital
DSS console (see Digital Direct Station Selection
Console) have the same dimensions:
Height: 3.6 in. (92 mm)
Width: 7.3 in. (184 mm)
Length: 9.0 in. (229 mm)
In standard form, all digital telephones may be
wall mounted without additional equipment and
are hearing aid compatible.

can also be upgraded with off-hook call
anounce, loud ringing bell, and headset inter-
face capability.
l
Simultaneous Voice and Data: Digital
telephones may be upgraded with an inte-
grated data interface unit (PDIU-DI) to
receive and transmit simultaneous voice
and data; data and voice calls can be
made independently of each other. The
PDIU-DI (Figure 5) is easily installed,
replacing the usual digital telephone base.
Asynchronous data devices, such as per-
sonal computers and terminals, can be
connected to the standard RS-232 connec-
tor of the PDIU-DI. Station users are able
to transmit and receive RS-232 data over
the PDIU-DI-equipped digital telephone’s
single twisted wire pair. 2B+D technology
enables the digital telephone and the
PDIU-DI to share the same wire pair and
station port (see Table D).
FIGURE 54NTEGRATED DATA INTERFACE UNIT
(PDIU-DI)
NOTE:
The PDIU-DI will function with all slots,
except slots 11 w 14 in DK96.
l
Off-hook Call Announce Upgrade: If
equipped with an off-hook call announce
(OCA) upgrade assembly, each digital tele-
phone may receive intercom calls when
the handset is off-hook.
l The OCA upgrade assembly for digital
t Requires Release 3 software
telephones is a small printed circuit
board, DVSU, which installs inside the
telephone base-with plug-in cormectors.
l Only those telephones programmed to
receive OCA announcements require a
DVSU.
l An extra wire pair is not required for
digital telephones to receive or originate
OCA, and no other subassemblies are
required for the Digital Telephone
Interface PCB (PDKU).
l Loud Ringing Bell/Headset Upgrade:
Each digital telephone may also be
upgraded to provide a loud ringing bell
interface and a modular headset interface.
To accomplish this, an upgrade assembly
consisting of a small PCB (HHEU) installs
inside the phone with a plug-in connector.
The loud ringing bell and headset options
are available simultaneously on a digital
telephone.
l Loud Ringing Bell: An external speak-
er (HESB) can be directly connected to
the upgraded phone. When the phone
e
rings, the HESB produces a loud tone
that mimics the phone’s ring. On voice
first intercom calls, the HESB amplifies
the caller’s voice announcement. See
the External Speaker option.
l Headset: Most standard headsets plug
into the HHEU jack and are compatible
with the digital telephone.
Option Combinations: A digital telephone may
use most of the .available upgrade options
simultaneously. For example, the same station
may be upgraded with a digital DSS console,
OCA, loud ringing bell, and headset. Digital
telephones upgraded with the PDIU-DI cannot
be wall mounted or upgraded with the loud
ringing bell, headset, or OCA interface, but
can be connected with digital DSS consoles.
Digital Direct Station Selection Consolet: The
Digital Direct Station Selection (DDSS) con-
sole is an optional, dedicated answering sta-
tion incorporating
a’busy
lainp field (Figure 6),
(
and can only be used with a digital telephone.
-6-
It is normally used on systems with a heavy
volume of incoming calls. A DDSS console
may be used with any digital station connected
to the first circuit on the digital telephone inter-
face PCB (PDKU). Up to four DDSS consoles
can be supported with a PCTU3 PCB.

DDSS consoles are equipped with auto-
matic line hold, and voice or tone signaling
capability. The consoles have 60 flexible
buttons, each with an associated LED (the
DDSS button LEDs will light red or green
depending on the button function). Each
flexible button can be assigned one of the
following functions:
All call page (pre-assigned)
CO line appearance
Direct station selection with busy LED
Night transfer (pre-assigned tenant 1 or
tenant 2, if necessary)
Speed dial
Each DDSS console requires one station
port on a PDKU, always the eighth circuit.
A DDSS console must be assigned to a
particular station when the system configu-
ration is defined in programming. All four
DDSS consoles can be assigned to one
station, or four different DDSS consoles
may be assigned to four different stations
(or any intermediate combination). The
same DDSS console may not be assigned
to more than one station.

Electronic Telephones
- Four different models of 6500-series electronic
telephones are available. The phones are en-
closed in a stylish, impact-resistant case (either
ash white or charcoal gray) with a matte finish,
and blend easily into any progressive office envi-
ronment. Toshiba electronic telephones that are
compatible with the analog STRATA/STRATA,
key telephone systems are also compatible with
the STRATA DK systems. However, some fea-
tures may vary (e.g. LCD and busy lamp field
telephones).
All 6500-series electronic telephones and DSS
consoles have the same dimensions:
Height: 3.6 in (92 mm)
Width: 7.0 in (178 mm)
Length: 9.0 in (229 mm)
In standard form all electronic telephones may
be wall mounted without additional equipment,
and they are also hearing aid compatible.
Each electronic telephone also features a
standard modular handset cord, and is connect-
ed to the system with a 2-pair modular line cord.
Various upgrade options, such as the off-hook
call announce and loud ringing bell upgrade
assemblies, require special wiring. A 3-pair mod-

ELECTRONIC TELEPHONE
Electronic Telephone Upgrade Options: All
electronic telephones may be upgraded with
off-hook call announce, loud ringing bell, and
headset capability.
l Off-hook Call Announce Upgrade: Each
electronic telephone may be upgraded to
receive intercom calls when the handset is
off-hook by installing an off-hook call
announce upgrade assembly.
l The assembly consists of two PCBs,
HVSU and HVSI, which install inside the
telephone base with plug-in connectors.
l Only those telephones programmed to
receive OCA announcements require
the OCA upgrade.
l Each station PCB (PEKU or PESU) that
supports electronic telephones with
OCA capability must be equipped with
an EOCU subassembly.
l Loud Ringing Bell/Headset Upgrade:
Each electronic telephone may also be
upgraded to provide a loud ringing bell
interface and a modular headset interface.
To accomplish this, an upgrade assembly
consisting of a small PCB (HHEU) installs
inside the phone with a plug-in connector.
l An external speaker (HESB) can be
directly connected to the upgraded
phone. When-the phone rings, the
HESB produces a loud tone that mimics
the phone’s ring. On voice first intercom
calls, the HESB amplifies the caller’s
voice announcement. See the External
Speaker option.
l Most standard headsets plug into the
HHEU jack and are compatible with the
electronic telephone.
l
An electronic telephone may use all avail-
able upgrade options simultaneously. For
example, the same station may be upgrad-
ed with a DSS console, OCA, a loud ring-
ing bell, and a headset.
Direct Station Selection Console: The Direct
Station Selection (DSS) console is an optional,
dedicated answering station incorporating a
busy lamp field (Figure 10). It is normally used
on systems with a heavy volume of incoming
calls. A DSS console may be used with any
station connected to the first circuit on a PEKU
PCB. Up to four DSS consoles can be sup-
ported with a PCTU PCB, and up to three with
a PCTUS PCB.
DSS consoles are equipped with automatic
line hold, and voice or tone signaling capa-
bility. The consoles have 60 flexible but-
tons, each with an associated LED. Each
flexible button can be assigned one of the
following functions:
l
All call page (pre-assigned)
0 CO line appearance
l
Direct station selection with busy LED
l
Night transfer (pre-assigned tenant 1 or
tenant 2, if necessary)
l
Speed dial
Each DSS console requires two station
ports (circuits 7 and 8) on an electronic
telephone interface PCB (PEKU). Only one
DSS console may be installed on a partic-
ular PEKU.
A D$S console must be assigned to a par-
ticular station when the system configura-
tion is defined in programming. All four
DSS consoles can be assigned to one sta-
tion, or four different DSS consoles may be
assigned to four different stations (or any
intermediate combination). The same DSS
console may not be assigned to more than
one station.

Door Phone: In one of its most popular applica-
tions, the door phone (Figure 12) mounts out-
side a building, next to a locked door whose
entry requires screening. An individual located
outside the building who wants to speak with
someone inside simply presses the button on
the door phone. A distinctive tone will then
sound over the speakers of the digital and/or
electronic telephones defined to do so through
system programming. Any digital or electronic
telephone user can answer and converse with
the individual at the door phone. If the system
is properly configured, the user can allow entry
using a door lock button on the digital or elec-
tronic telephone.
l
A door phone also functions as a sound
monitor. Any telephone can call the door
phone and listen to sounds within its
immediate area.
l
Up to twelve door phones can be support-
FlGURE12-DOORPHONE
ed with a PCTU, up to nine with a PCTUS.
A door phone/lock control unit
- (HDCB-Figure 13) must be installed to
support up to three door phones (or two
door phones and one door lock control).
Each HDCB requires one station port on
an electronic telephone interface PCB
(PEKU or PESU). Only one HDCB can be
installed on a particular PEKU or PESU.
FlGURE13-DOORPHONE/LOCK
CONTROLUNlT(HDCB)
NOTE:
The PDKU cannot support an HDCB.
l
Door lock control requires an optional
interface PCB (PIOU, PEPU, or PIOUS)
and/or an HDCB. Up to five door lock con-
trols can be installed, but each door lock
controlled by an HDCB reduces the door
phone capacity on that HDCB from three
to two.
External Speaker: The HESB external speaker
unit is a 6-inch, 3-watt speaker with a built-in
amplifier (Figure 14). A +12 VDC power supply
(HACU-120) is included with each external
speaker. It connects to the back panel with an
8-foot cord and plugs into a 117VAC, 60 Hz
outlet. The HESB has three applications:
l
Amplified Paging Speaker: Allows the
HESB to be used as a paging speaker,
reducing the need for other manufacturers’

l
Loud Ringing Bell: Allows the voice/tone
of a paging/ringing call to any digital tele-
phone or 6500-series electronic tele-
phone to be amplified. When an HESB is
connected as a loud ringing bell, an
HHEU upgrade assembly must be
installed in the digital or electronic tele-
phone’s base. See the loud ringing
bell/headset telephone upgrade in the last
section. An external speaker cable
(HESC-65 for electronic telephones;
