Toshiba Strata Dk14, Dk40i, Dk424i General Description Manual

							Station Features
Microphone (External Unit)
Strata DK General Description    6/00105
Microphone (External Unit)
An external microphone (RFDM) can be connected to the DKT2020-FDSP digital telephone 
enhancing “full-duplex” operation by virtue of the “superdirectional” characteristic of the 
microphone. When this option is on, the internal microphone is disabled on all but Voice First 
Handsfree Answerback calls and OCA calls. The external microphone is powered by the DKT and 
does not need to be turned off when not in use.
Modem Button
This button enables a digital telephone user to reserve a modem from a pool or to switch from a 
voice to a data call. Its LED indicates the availability of modems. The telephone must be equipped 
with an Integrated PC Interface Unit (RPCI) for 
	 button applications.
Modular Handset and Line Cords
All Toshiba telephones are equipped with modular handset and line cords.
Modular Headset
Digital telephones may be optionally equipped with a modular headset jack by installing an HHEU 
PCB.
Off-hook Call Announce (OCA)
OCA allows a station user to send a voice announcement to a busy digital or electronic telephone. 
The call must be directed to a station’s [PDN] or [PhDN]. OCA will not occur when the called 
station is not the owner of the dialed [PDN] or [PhDN]. Only the [PhDN] owner telephone can 
receive OCA on calls to the [PhDN].
In order for a station to receive OCA, the station must be assigned with OCA-receive capability in 
the system database. Depending on system programming and hardware availability, the called 
station can receive OCA in one of the following ways:
Handset Mode
An OCA announcement can be sent through the handset receiver to called party who is off-hook 
and engaged in a conversation. Only digital telephone sets can have this feature. If the called 
party’s station has been programmed with Handset Mode and OCA-receiving capability, an OCA 
warning tone (optional) and announcement can be sent to through the handset. Cordless digital 
telephones will also receive the warning tone and announcement.
The called station user, while off-hook and engaged in a conversation, will hear the outside talking 
party and the OCA calling party, but the outside talking party cannot hear the OCA calling party. 
The called station user can hold down the 
 button to respond and talk to the OCA calling party 
through the handset; the outside talking party will not hear the response.
A digital telephone feature button can be programmed to work with “push-on/off” action. When 
“push-on/off” is used, the outside party will hear MOH, if installed, when the called party talks 
back to the OCA party; otherwise, the outside party hears nothing when excluded from the talk 
path. Receiving handset OCA calls is available to digital telephones only; no special hardware 
additions are required. 
						

							Station Features
On-hook Dialing
106Strata DK General Description    6/00
The DKT2001 telephone can receive handset OCA annoucements, but the user cannot respond, 
since the DKT2001 does not have 
 button.
Speaker Mode
An OCA announcement can be sent through the speaker to a called party who is off-hook and 
engaged in a conversation. The called phone user must be equipped with a digital telephone with 
the optional DVSU PCB and the station must be programmed for OCA-receiving capability. 
Cordless digital telephones are not compatible with Speaker OCA.
The called station user can respond to the OCA caller by talking into the telephone’s microphone. 
With more than one party connected, two-way simultaneous conversations are possible. However, 
the RPCI PC/Data Interface cannot be used if speaker mode OCA is installed or vice versa. 
Electronic telephones are compatible with speaker OCA (optional hardware is required).
On-hook Dialing
Digital and electronic telephone users can dial calls without lifting the handset, freeing their hands 
for other tasks. System dial tone, dial pulsing, ringing, and the voice of the answering party are all 
heard over the telephone speaker. The handset does not need to be lifted until after the party 
answers, and on speakerphone models does not need to be lifted at all.
Personal Computer Interface (RPCI-DI)
An optional PC interface unit that replaces the normal digital telephone base and provides the 
telephone with simultaneous computer-telephone interface and voice/data features as described in 
“Integrated PC Interface (RPCI-DI)” on Page 57.
Pooled Line Buttons
A group of CO lines can appear under one button on digital and electronic telephones. The system 
can support up to 16 line groups. A station can have up to four buttons for the same group for 
handling calls in the same group. Pooled and single appearing line buttons are designed for use 
with loop and ground start lines, not Tie, DID, DNIS, or ANI lines.
Private CO Lines
The system can be programmed to allow certain “private” CO lines to appear only on one digital or 
electronic telephone and is accessible only by that station.
Push-button Dialing
All Toshiba telephones are equipped with push-button dial pads.
Release Button
Users can complete a transfer or disconnect from a call and become idle just by pressing an 
optional 

 button on their digital telephones; going on-hook or pressing the hookswitch is 
not required. This feature is useful for headset-equipped stations. 
						

							Station Features
Release/Answer Button
Strata DK General Description    6/00107
Release/Answer Button
The 
and

 button enables a station user that is talking on a call to release and transfer 
or disconnect the active call and automatically answer a new incoming call. This is useful for DSS 
console’s telephones or stations that must process many incoming calls.
Remote Retrieval of Held/Parked Calls
Calls placed on hold or parked by a station can be picked up selectively by another station by 
pressing a feature button or dialing an access code.
Repeat Last Number Dialed
The last number dialed by a digital or electronic telephone is stored in system memory, and may be 
redialed automatically by accessing a CO line and pressing 
	 or dialing an access code. 
Ringing Line Preference
A digital or electronic telephone user with this programmable-by-station feature can answer an 
incoming CO, DID, or Tie line call ringing at their station just by lifting the handset or pressing the 
 button, without having to press the button associated with the line.
Saved Number Redial
After dialing a telephone number, a digital telephone user can “save” the number by pressing an 
optional feature button. The system will automatically redial the saved number when the user 
accesses a [DN] or CO line and presses the button again.
Speed Dial Buttons
This feature enables digital station users to dial telephone numbers with the push of a button. 
Standard telephones can dial System and Station Speed Dial numbers with access codes. There are 
two types of Speed Dial buttons:

Station Speed Dial Buttons – Station users can store their own personal telephone numbers 
on Station Speed Dial buttons. Each button uses one of the assigned 40 station speed dial 
number storage locations.

System Speed Dial Buttons – A designated station user can store numbers for System Speed 
Dial buttons, which can be assigned to any digital or electronic telephone. For the number of 
available system speed dial numbers, see “System Speed Dial” on Page 87. 
						

							Station Features
Telephone Application Programming Interface (TAPI) Compatibility
108Strata DK General Description    6/00
Telephone Application Programming Interface (TAPI) 
Compatibility
The DK can interface with computer applications which conform to the Microsoft Windows TAPI 
format. TSPI software, which allows the DK to communicate with TAPI applications, is bundled 
with the RPCI in the form of a 3-1/2” IBM-compatible disk. 
The TAPI connection is made with a customer-supplied RS-232 cable connected to a 
communication port on a PC and through a DKT2000-series digital telephone with an installed 
RPCI. The PC must be able to run Microsoft Windows software.
Timed Reminders
Five separate “reminders” (i.e., a tone which sounds at a preset time) can be set at any telephone to 
ring only once or at the same time daily.
Toll Restriction Override Code Revision
Privileged digital telephone stations can change Toll Restriction Override Codes.
User Programmable Feature Buttons
This feature enables digital and electronic telephone users to program their personal Speed Dial 
buttons with codes to access features and/or dial telephone number. As many as 20 digits and 
button functions—such as Hold, [PDN] access, and Conference/Transfer (two digits each)—can 
be stored. More than one feature can be linked under one button to allow functions like placing a 
line on hold and accessing the Page system with the touch of one button.

PC Attendant Console Features8
The Strata DK PC Attendant Console (DK-PCATT) offers many new features, not available on the 
older model DK Attendant Console (see  on Page 119). Additionally, it offers all of the features 
available on digital telephones and the older DK Attendant Console. Most features can be operated 
either from the DK-PCATT-KB keyboard or from a PC mouse.
The Strata DK PC-ATT software runs on the computer as a Windows application. Toshiba 
recommends using a dedicated PC for the console; however, other applications can run 
simultaneously on the same PC. The PC can toggle between Attendant Console mode and other 
applications.
The console commands are similar to other Windows applications, making training easier for 
previous Windows users. Either a mouse or keyboard can be used for console operation.
NoteFor minimum requirements and an illustration of the DK-PCATT screen, see “Strata 
AirLink Wireless Systems” on Page 60.
This chapter describes specific console features that are available to DK-PCATT users.
Answer Button
Automatically answers the next ringing call based upon the system defined priority (incoming CO, 
recall, transferred, etc.—see Answer Priority). Multiple ringing calls are automatically queued to 
the 


/ button. The system can prioritize on a first-in first-out (FIFO) basis, or according to 
the priority defined by the user with the Answer Priority feature.
Answer Priority
Enables the 

/ button to answer multiple ringing calls in a priority sequence. The priority 
sequence is programmable except for emergency calls, which are always the highest priority. The 
program default priority sequence is (highest to lowest) Emergency Call, Park Orbit Recall, 
Transfer Recall, Hold Recall, Transferred to “O” Call, Incoming CO Line Call, Internal “O” 
Operator Call, Internal to Operator Directory Number [DN] Call.
Answer Prompting
When an incoming call rings the console, the screen displays can display prompts for answering 
the various CO line or DNIS call. These prompts are stored from the console. 
						

							PC Attendant Console Features
Attendant Conference Setup
114Strata DK General Description    6/00
Attendant Conference Setup
This enables the Attendant to set up a conference call with up to four members. Conference 
members can be another console, station, or CO line user. The conference can be originated by the 
Attendant or requested by a station user or outside party.
Auto Day/Night Mode Switching
The DK-PCATT can automatically switch the Strata DK between Day, Day2, and Night modes, 
according to the time of day and day of week. Parameters are programmed from the attendant 
console. With automatic mode switching, the 
#(
 button does not have to be 
pressed. Automatic mode switching is only available with a DK-PCATT and is not a standard 
system feature of the Strata DK.
Auto Dialing
When Auto Dial is on, the DK-PCATT can search for names and numbers in the directory, and 
then automatically dial the number. If Auto Dial is off or no match is found, the Attendant can use 
the directory and press a button to call a party or enter a number to be dialed.
Busy Lamp Field (BLF) Display
The console screen shows station status (busy/idle), so the Attendant can see who is busy. BLF 
data displays in the directory area of the screen, either with or without station names.
Call Waiting Count
The number of calls waiting to be answered in the attendant console answer queue is displayed and 
constantly updated.
Color CRT Display
Console text information is displayed on the monitor screen in full color. Various colors indicate 
different status or conditions, making them more distinguishable to the Attendant.
Dial “O” For Attendant
Up to four attendant consoles can be installed per system. To call any available console, station 
users dial O. To call a specific console, dial the specific console [DN].
Dial Outside Number For Station User
The Attendant can access a CO line and dial an outside destination number for a station user. To do 
this, the Attendant must be in the talk state with a station user, an outside caller, or a caller on an 
incoming Tie trunk.
