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-

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.

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.

0

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-

ular line cord is required for off-hook call

announce, and a custom external speaker cable

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:
