assignment may be assigned to the system for 
zach DAY, DAY2 or NIGHT mode (see 
DAY/NIGHT Modes). If a station is pro- 
grammed to ring for a particular CO line, then 
a choice may be made between three timing 
specifications: 
l Immediate: Stations assigned IMMEDI- 
ATE timing ring as soon as the CO line 
rings into the system. 
l Delay 1: If stations with IMMEDIATE tim- 
ing have not answered within 12 seconds 
(three rings), stations assigned DELAY 1 
timing begin ringing also. 
l Delay 2: If the above stations have not 
answered within 24 seconds (6 rings), sta- 
tions assigned DELAY 2 timing begin ring- 
ing also. 
Flexible Port/Line Assignment: The system’s 
universal slots can be assigned to station, CO 
line, or E & M TIE line PCBs in a variety of 
custom configurations. See System Capacity 
and Configuration. 
Group Paging*: Dialing a 2-digit access code 
permits a user to make vocal announcements 
to one of four internal station groups or all sta- 
tions simultaneously. Any station receiving an 
announcement can directly access the origina- 
tor by dialing a code, although any other sta- 
tion receiving the announcement will be cut 
off. Stations are assigned to groups when the 
system is programmed. This feature is inde- 
pendent of external paging zones, which reach 
external speakers (see External Zone Paging). 
Least Cost Routing*: Eight different routing 
plans may be designed to automatically place 
outgoing calls using the most cost-efficient 
method. Three different LCR time schedules 
can be set up for the business day. Each 
schedule can use a different priority sequence 
to place calls, depending on the time of day. 
Stations can be grouped into one of four class- 
es of LCR. Each class has its own routing pri- 
ority. Selected station users may have priority 
use of a line, even when the route with the 
lowest cost is not available. LCR is compatible 
with ABR and two CO line conference. 
*Available using standard or electronic telephones. 
Live System Programming: Programming the 
system does not normally interrupt service. 
When the system is>rogrammed on-site, only 
the station executing commands loses normal 
function. When the system is programmed 
from a remote terminal, all stations remain 
functional. Service is only interrupted for hard- 
ware upgrades. 
Memory Protection: If the power fails, the sys- 
tem has an internal battery backup that pro- 
tects data and the customer’s programmed 
configuration. This information will be main- 
tained within a powerless system for approxi- 
mately six years. 
Message Waiting: Any station and most voice 
mail devices can leave a message waiting 
indication at a digital or an electronic station 
which causes the called digital station’s MES- 
SAGE LED or called electronic station’s 
MW/FL LED to flash. In such a case, the sta- 
tion user can either automatically recall the 
originating station or voice mail device, or can- 
cel the indication without responding. Up to 
three indications sent by other stations will be 
queued. A fourth indication is always reserved 
for the Message Center. 
l The system message waiting feature inte- 
grates with most voice mail/auto attendant 
devices by providing special codes that 
allow the device to set and cancel the 
message waiting LEDs on the digital and 
electronic telephones. The digital and elec- 
tronic teleohones automatically retrieve the 
message ‘via the m-and m 
buttons respectively. 
Music-on-Hold*: A customer-supplied music 
source, such as a radio or tape player, can be 
connected to the system. CO lines or stations 
placed on hold connect to the music-on-hold 
source, and the holding party hears music. 
l The music source can be connected 
directly to the controller PCB (PCTU or 
PCTUS). An optional interface PCB is not 
required to support this feature. However, 
if the system is to be-configured with a 
tape recorder that plays a pre-recorded

message to holding parties, the option 
interface unit PCB (PIOU, PIOUS, or 
PEPU) is suggested. 
The interface PCB has a relay that can be 
programmed to control a tape player every 
time a call is placed on hold. When the 
relay activates, the tape plays. When the 
call goes off hold, the tape stops. The tape 
recorder does not need to run continuously 
in order for the taped message to reach 
holding parties (see Relay Service). 
Music-on-hold and background music can 
share a music source or have individual 
music sources (see Background Music). 
Night Ringing Over External Page*: When the 
system is in Night mode, and an incoming call 
from a CO line or door phone is received, the 
system can be programmed for ringing to 
sound over an external speaker. When this 
feature is used, persons working after-hours 
are more likely to answer important calls, 
especially if they work away from a telephone. 
The customer-supplied external speaker 
requires an option interface PCB (PIOU, 
PIOUS, or PEPU) to support it. See Night 
Ringing Over Selected Page Zones. 
l Any station in the system can answer the 
call by dialing the Night Pickup code. 
Night Ringing Over Selected Page Zones+: 
CO lines can be programmed to night ring 
over selected PIOU page zones via customer- 
supplied paging equipment. The lines can be 
divided into two groups (tenant 1 and tenant 2) 
which can then be assigned to night ring over 
the selected zones, 1 N 4. 
Non-blocking Talk Paths*: All CO and inter- 
com lines can be used at the same time. The 
system can operate at full capacity at all times. 
Off-premises Station: An off-premises station 
is a standard telephone located off-site from 
the system. Each is supported by one stan- 
dard telephone interface (PSTU or PESU) 
port, and normally requires a special line from 
the central office. Each PSTU supports up to 
eight off-premises stations, and each PESU supports up to two off-premises stations. 
Outgoing Call Restrictioti: Statidns’can be 
selectively restricted from originating calls over 
any number of CO lines. Only outgoing calls 
are restricted. The same stations can receive 
incoming calls over the restricted CO lines. 
Page Interface*: Dialing a 2-digit code permits 
user access to a customer-provided external 
speaker through an internal 3-watt amplifier, or 
a two-way 600-ohm voice path is available for 
use with a customer-supplied talkback speak- 
er/amplifier. The external amplifier and speak- 
er are optional, and an option interface PCB 
(PIOU, PIOUS, or PEPU) is required to sup- 
port them. 
NOTES: 
1. 
2. 
Page can be accessed by all stations 
and TIE lines (optional), but not 
DISA/DISC lines. 
The 3-watt amplifier is included with 
either a PlOlJ or PEPU, but not on the 
PIOUS. 
Page Zones*: Dialing a 2-digit access code per- 
mits a user to page to one of four external 
zones or all zones simultaneously. External 
zones are composed of customer-supplied 
speaker(s) and amplifier(s). This feature is 
independent of group paging, which reaches 
internal station groups (see Group Paging). 
The external speakers required to operate this 
feature are optional. An option interface PCB 
(PIOU) is required to support them. The 
PIOUS or PEPU provides one external zone 
only. 
NOTE: 
Zone page can be accessed by all stations 
and TIE lines, but not DISA/DISC lines. 
Pooled CO Lines: Several CO lines can be 
pooled to appear under one station CO line 
button. CO lines can’ be pooled in categories, 
e.g., all WATS lines in one pool, all regular CO

lines in another pool, etc. 
*---Outgoing pooled line buttons override sys- 
tem LCR, and cannot be used to set up 
tandem CO calls. 
l Pooled line buttons can be used to set up 
two-CO line conference calls with one or 
two stations. 
Power Failure Transfer: Up to eight CO lines 
are switched directly to up to eight dedicated 
conventional telephones (customer-provided 
2500- or 500-type) for incoming and outgoing 
calls. This feature requires an external unit, 
the power failure transfer unit (DPFT). A stan- 
dard telephone interface unit (PSTU) is 
required to supply the DPFT with a -24VDC 
control signal and ground connections. 
Privacy/Non-privacy: The system can be pro- 
grammed to be totally private or non-private, 
or any combination of private/non-private on a 
station-by-station basis. The system is in pri- 
vate mode by default, meaning that station 
users, by pressing the CO line button, cannot 
access a CO line that is in-use by another sta- 
tion. Station users, however, can change their 
individual station’s mode via the privacy 
release button. Users having stations with 
common CO line appearances can access a 
CO line that is currently in use by a non-pri- 
vate user. Up to three stations may converse 
on a single CO line via non-private operation. 
See Station Features, Privacy Release Button 
and Privacy Override. 
NOTES: 
1. In private systems (default), all stations 
are denied Privacy Override. 
2. In nonprivate systems, all stations are 
allowed Privacy Override. 
Relay Service: Two relays provide signals to 
activate optional external equipment. Each 
relay can be optionally configured to be nor- 
mally open or normally closed. Each relay can 
be programmed to perform one function only. 
Relays and their optional functions are as fol- 
lows: l External Page/Door Lock 
Relay: This 
relay can be programmed to activate one 
of the following functions: 
. 
l External Page: An external music 
source can be connected to the system 
to provide background music over exter- 
nal speakers. When a paging announce- 
ment is made over the external speak- 
ers, the external page relay mutes the 
background music. 
l Door Lock Control: This relay controls 
an electronic door lock. When the sta- 
tion door lock button is pressed, the 
door is unlocked by the relay for either 3 
or 6 seconds as specified in program- 
ming. 
l Night/Hold Relay: This relay can be pro- 
grammed with one of the following func- 
tions: 
l Night Relay: The night relay activates if 
the system is in night mode and there is 
an incoming CO line or door phone ring. 
In programming, the relay can be set to 
activate continuously (for indirect ( 
answering machine control) or pulsating 
at 1 second ON/3 seconds OFF (for a 
night bell) when a CO line or door phone 
rings. 
l Hold Relay: The hold relay activates 
any time a CO line is on hold. It is nor- 
mally used to control the music-on-hold 
source. A common source controlled by 
this relay is a tape deck (see Music-on- 
Hold). 
NOTES: 
1. Door lock control is also provided via 
HDCBs (see Door Lock Control). 
2. Both relays reside on the option inter- 
face PCB (PIOU, PIOUS, or PEPU). 
Therefore, a PIOU, PIOUS, or PEPU is 
required for any relay functions dis- 
cussed above. 
Remote Administration and Maintenance: 
System administration, programming, and 
maintenance can be performed from a remote l 
-36-  
						

							location, over a customer-supplied ASCII ter- 
minal and modem. The system remains live, 
with no interruption to operation. 
l Remote access of system programming/ 
maintenance is accomplished by calling in 
on CO lines that connect to the mainte- 
nance modem (direct ring or transfer). A 
customer-supplied commercial modem or 
an internal modem unit (IMDU) with a sup- 
porting option interface PCB (PIOU or 
PIOUS) are required to support this fea- 
ture. 
Reserve Power: Two customer-supplied 12-volt 
batteries can be connected to the system as a 
power failure backup. The batteries are con- 
nected to the system’s standard power supply, 
therefore, no optional interface PCB is 
required. When electrical power is intact, the 
battery continuously trickle charges to capaci- 
ty. The battery charger is built into the power 
supply. In the event of a power failure, the sys- 
tem automatically switches over to battery 
power without any interruption to existing calls 
or other normal system function. The length of 
time reserve power will operate depends upon 
the number of batteries provided, and the sys- 
tem load (see Table B). 
IMPORTANT NOTES: 
1. Local ordinances may dictate battery 
type, housing, and installation 
method. 
2. Batteries must be connected when 
the system is operating via AC power 
(if batteries are installed after the AC 
power fails, they will not operate the 
system). 
3. Batteries are connected to the sys- 
tem with the Toshiba-supplied PBTC- 
3M cable. 
Station Hunting*: When a called station is 
busy, the call will hunt to an assigned station. 
If the assigned station is busy, the call hunts to 
the next assigned station, and so on. The call 
is eventually routed to the first idle station. The 
hunting sequence can be either consecutive or 
non-consecutive, and is fully flexible. If a hunt 
-37- STRATA DK 
GENERAL DESCRIPTION 
DECEMBER 1990 
station is call forwarded, calls to the station will 
ring at the forwarded destination-not the hunt 
_ destination. 
Station Message Detail Recording: The sys- 
tem provides detailed information regarding 
both incoming and outgoing calls. The infor- 
mation includes time and duration of a call, as 
well as the called number. It can also include 
account codes entered (forced and voluntary), 
the time it took to answer a call, and the sta- 
tion to which a call was transferred. Calls may 
be screened to print out all calls, outgoing 
only, or outgoing long distance calls only. 
l The system provides the information 
through an RS-232 port (ASCII), which is 
compatible with most commercial printers 
and call accounting devices. Such cus- 
tomer-supplied peripherals may be capa- 
ble of providing sophisticated account 
tracking and reporting features. 
l Station message detail recording is option- 
al, and an option interface PCB (PIOU or 
PIOUS) is required to support it. 
System Programming through Station: The 
system is easily programmed through an LCD- 
type digital or electronic telephone connected 
to PEKU port 05. The programming electronic 
telephone functions the same as any other 
station when it is not in programming mode. 
See Live System Programming. 
System Speed Dial*: Up to 40 system speed 
dial numbers can be stored by the digital or 
electronic telephone connected to PEKU port 
00. Each number can be up to 20 digits, and 
IO of the 40 numbers can be linked to any 
other speed dial number to automatically dial 
up to 37 digits. Any station in the system can 
speed dial the stored number by pressing a 2- 
digit access code or a previously programmed 
q button. Names may be assigned to each 
number for LCD telephone users. Speed dial 
buttons (locked or fixed) can be configured for 
one-button access to Centrex/PBX features. A 
fixed 
q button cannot be changed except by 
station 200. See Station Features, Speed Dial 
Buttons and Station Speed Dial. 
*Available using standard or electronic telephones.

GENERAL DESCRIPTION 
DECEMBER 1990 
Tandem CO Line Connections: This feature 
altews an unattended line-to-line connection, 
leaving the originating station free to make 
another call. For supervision purposes, the 
originating station must have both CO line but- 
ton appearances to allow tandem operation. 
Therefore, tandem calls cannot be set-up from 
standard telephones, digital telephones, or 
electronic telephones using LCR, pooled line 
buttons, or CO line access codes. 
Tenant Service: Two small businesses in the 
same office building which do not each require 
a full system can share a system. Each ten- 
ant’s CO line buttons appear in the correct 
sequence on stations. Each tenant can have 
two dedicated DSS consoles. Tenants can 
also call each other directly. Tenants can have 
separate: 
l LCR and toll restriction plans. 
l Night transfer ringing assignments. 
l Flexible door phone and CO line ringing 
assignments. 
TIE Lines: TIE lines can be installed to link 
STRATA DK systems to one another, or to link 
a STRATA DK system to a PBX or any other 
system with TIE lines. System configuration 
allows a maximum of four TIE lines on DK24, 
eight on DK56, and twelve on DK96. TIE lines 
are interfaced via the PEMU PCB, each of 
which provides four circuits. TIE lines are E & 
M Type I signaling, optional 2- or 4-wire trans- 
mission, immediate start. 
l Paging system (external and station 
speakers) access by far-end callers origi- 
nating TIE line calls can be denied or 
allowed in system programming. 
l System programming allows or denies 
handsfree answerback on incoming TIE 
line calls. 
l Off-hook call announce is not available 
over TIE lines. 
Toll Restriction*: Stations can be individually 
restricted from making toll calls. Four restric- 
tion levels can be defined, each allowing or 
denying specific area and office codes, long 
distance information calls, international calls, 
t Requires Release 3 software. 
and/or operator-assisted calls. Each station is 
assigned any one of t.he available restriction 
levels or no restrictionT Individual CO lines can 4 
be defined as unrestricted. By dialing one of 
the two toll restriction override codes pro- 
grammed into the system, a user can bypass 
toll restriction. Also, a user can temporarily 
change a station’s toll restriction class (See 
Station Features: Traveling Class of Service, 
Toll Restriction Override Code Revision, and 
Verified Account Codes).T 
Toll Restriction Override by System Speed 
Dial*: System speed dial numbers can be 
programmed to override toll restrictions. For 
instance, when employees need to access a 
toll number that falls into a restricted area/ 
office code for work purposes, an employer 
can program the particular toll number as a 
system speed dial number. Even if their sta- 
tions are toll restricted, they can access the 
number with speed dialing. 
Transfer Privacy: Optional transfer privacy can 
be programmed system-wide. When transfer 
privacy is programmed and an outside call is 4 
answered by one station, then transferred to 
another station, it can only be answered by the 
second station, or by a station with directed 
call pickup. Other stations cannot pick up the 
transferred call with a CO line button. See 
Alternate Point Answer and Directed Call 
Pickup. 
Traveling Class of Service-t: The normal toll 
restriction class of a station can be temporarily 
changed to another class. Each of the four toll 
restriction classes can be assigned a four-digit 
code. If one of these codes is entered at any 
station, the station will assume the class asso- 
ciated with the code for the next dialed num- 
ber. The station will revert back to its normal 
toll restriction class for subsequent calls. In 
system programming, any station can be 
assigned to change these codes. The traveling 
class code data is not sent out the SMDR port 
and will not print out on station call records. 
Traveling class codes can be added, deleted, 
or changed by users from stations selected in 
programming. I

com lines can carry handsfree conversations 
simultaneously. Because intercom paths are 
non-blocking, the’ number is only limited by the 
amount of digital and electronic stations.

length and will dial automatically on for- 
warded and hunt-type calls, or when 
responding to an MW indication. 
To support a voice mail system, an option- 
al standard telephone interface unit PCB 
(PSTU or PESU) must be installed in the 
STRATA DK system. 
Voice Mail Interface*: The system can be con- 
figured with a Toshiba- or customer-supplied 
voice mail messaging system. Depending 
upon the voice mail product installed, some or 
all of the following features may be provided: 
call routing, message handling, information 
management, etc. 
l Automated Attendant: An integrated 
Automated Attendant can streamline the 
system’s call answering capability. Addi- 
tionally, the supervised transfer capability 
virtually eliminates unanswered or missed 
calls. 
l Call Forward to Voice Mailbox: Each 
telephone user can forward calls directly to 
a personal mailbox. The caller bypasses 
the usual sequence of voice mail.com- 
mands, and simply leaves a message after 
hearing a tone. Voice or Tone Signaling*:‘ Each method suits 
different business needs, and the calling sta- 
tion can select the other setting at any time, 
regardless of the system’s programming. In 
addition, the intercom tone can be optionally 
disabled, via system programming, to each 
station individually to allow room sound moni- 
toring. The system can be programmed to 
announce calls in one of two ways: 
l Voice First: Can be more convenient, 
enabling the called party to answer without 
touching the station. A distinctive intercom 
tone sounds over the receiving station’s 
speaker, followed by the caller’s voice. 
l Tone First: Ensures a conversation’s pri- 
vacy. The intercom tone sounds over the 
receiving station’s speaker every four sec- 
onds, until the station user answers the 
call. See Station Features, Distinctive 
Ringing. 
l Message Waiting Indication: When a 
message is recorded in a user’s mailbox, 
the voice mail system automatically sets a 
message waiting indication at the user’s 
station. When the station user listens to 
the message, he/she can erase the mes- 
sage, allowing the voice mail device to 
automatically turn off the indication. 
l Voice Mail Control via Station: Station 
users can control voice mail equipment 
from their telephone dialpads. 
l Feature Integration: The integration of 
special voice mail features in STRATA DK 
system software enable the systems to 
work together more efficiently. 
l Voice Mail Identification Codes: Each 
station user can set VM ID codes to auto- 
matically route calls directly to his/her mail- Wall or Table Mounting: The cabinet can be 
mounted on the wall or table top. Special 
brackets shipped with every cabinet may be 
installed on the rear of the cabinet to provide 
recommended clearance from the mounting 
surface. 
Digital and Electronic Telephone Features 
Account Code Buttont: Allows users to enter 
voluntary account code (verified or not) during 
a conversation without interrupting the conver- 
sation. 
Automatic Busy Redial: If a station user dials 
an outside number and gets a busy signal, the 
user can hang up and have automatic busy 
redial (ABR) dial the number until the call com- 
pletes. ABR retries the number either every 30 
or 60 seconds up to 15 times. When the call

successfully completes, the originating station 
.%eunds a distinctive ABR tone. No optional 
hardware is required to support ABR. ABR is 
compatible with LCR. 
Automatic Callback*: If a station user dials 
another station over an intercom line and gets 
a busy signal, the user can hang up and have 
automatic callback (ACB) redial the number. 
When the busy station is freed, ACB calls the 
originating station. When the originating sta- 
tion user answers the ACB recall, the system 
rings the called station. The callback request 
will stay active indefinitely until either the 
called station is freed, or the caller cancels the 
ACB request. programmed to ring at a single station (and 
that station is forwarded). All CO lines trans- 
ferred to a forwarded station.will forward, 
When a station is in a call forward mode, it is 
allowed to originate telephone calls as usual. 
There are five different call forward modes 
available for each station. Each mode is 
set/canceled by the station user via individual 
call forward buttons or dial access codes. The 
call forward modes are: 
l All Calls: When a station is idle or busy, 
all calls to the station will forward immedi- 
ately and the station will not ring. 
l Busy: When a station is busy, all calls to 
the station will forward immediately. When 
the station is idle, incoming calls will ring 
normally. 
Automatic Hold/Park Recall*: A CO line or 
l No Answer: When a station is idle, calls 
intercom call placed on-hold or parked will 
to the station ring for 12 seconds2 and then 
automatically recall the station after a previ- 
ously programmed time period. A different forward. When the station is busy, incom- 
time period can be selected for each station. ing calls will receive busy tone when call- 
ing the station. 
Automatic Line Selection: Each station can be 
programmed so that when the handset is lifted 
or the m button is pressed, a CO line, CO 
line group, or intercom line is automatically 
accessed. 
Background Music with Station Control: A 
station user may control background music 
playing over the station’s speaker. The music 
may be switched on or off and the volume may 
be adjusted to suit the individual user. A desig- 
nated station (200) can control (on/off) back- 
ground music played over the external page 
speakers. 
l Busy/No Answer: When a station is idle, 
calls to the station ring for 12 seconds and 
then forward. When the station is busy, 
incoming calls will forward immediately. 
l Fixed: When the station is either idle or 
busy, all incoming calls will forward imme- 
diately and the station will not ring. Fixed 
call forward is different from the other call 
forward modes in that the destination sta- 
tion is set once in system programming, 
not selected each time the user sets the 
station in a call forward mode. 
Busy Override*: Upon calling a busy station 
and receiving a busy tone, the caller can dial 1 
to sound a tone burst to the called station. 
Busy Override is available to all stations and 
cannot be blocked. NOTES: 
1. The alternate station or device is select- 
ed by the station user when setting call 
forward (all calls, busy, no answer, and 
busy/no answer). With fixed call forward, 
the alternate station or device is select- 
ed in system programming for each sta- 
tion. 
Call Forwarding: When a station is set in a call 
forward mode, calls to the forwarded station 
are routed to an alternate station or voice mail 
device. This feature applies to both intercom 
and designated CO line calls. Incoming CO 
line calls will forward only if the CO lines are 2. If voice first, one ring tone will occur, 
then voice announce. If tone first or CO 
line call, three rings occur before for- 
warding activates. 
3. The system’can 66 programmed to

call forward feature and ring stations set 
in the call forward mode. This allows 
attendants to notify users that may have 
forgotten their telephones are in the call 
forward mode. 
Call forward takes precedence over sta- 
tion hunting destinations. 
All call forward modes are available to 
all stations; however, only one mode 
can be activated on a particular station 
at a time. 
If system power is removed, call forward 
information remains set on stations 
when power is restored. 
The call forward destination station can 
call the forwarding station. 
Call Park*: A station can place an existing call 
on park/hold and consult by placing another 
call. After consulting, the original call can be 
retrieved. This feature can also be used to 
park an outside CO line call, then page a per- 
son internally to pick up the call. Any station 
can’pick up the parked CO line calls selective- 
ly by dialing an access code plus the CO line 
number. 
NOTE: 
When a call is parked, the CO line LED will 
flash at the on-hold rate. 
Call Pickup*: By going off-hook and dialing an 
access code, any station can pick up: 
Calls on-hold or parked (selectively). 
Calls ringing at other stations. 
An external page. 
CO line ringing at night over external page 
or niaht bell.

Call Transfer with Camp-on*: Allows an out- 
side call to be transferred to an idle or busy 
station (camp-on). Recall occurs if the call is 
not answered within a specified time period. 
The recall time period is flexible, and can be 
programmed for different times for individual STRATA DK

stations. The recall time set in programming 
for each station is the time it will take to recall
