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-

electronic telephones, and IOOO-series digital telephones. Station capacities using older 
Toshiba electronic telephones are given in STRATA DK installation documentation. 
2. installing a TIE line (PEMU) PCB or an optional interface (PIOU, PIOUS, or PEW) PCB 
reduces available CO lines by four or available ports by eight.

GENERAL DESCRIPTION 
DECEMBER 1990 
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.
