Continuous DTMF Signal Time
Dual Tone Multi-Frequency (DTMF) dial signal is transmitted to the CO line or voice mail/Auto 
Attendant device for as long as the telephone user presses a button on the dial pad. This feature 
operates on 2000-series digital telephones only.
The maximum DTMF duration is determined by the length of time the user presses a button on the 
dial pad. The minimum DTMF duration is determined by system programming. A minimum 
DTMF duration, either 80 or 160 ms, is required when using Speed Dial and when sending voice 
mail integraton digits to a voice mail machine.
Benefits
Provides compatibility with a variety of outside services and devices, which require manually 
dialing DTMF tones of varying lengths. Application examples are MCI credit card calling, which 
requires holding down a button (to create a tone) for one second to make another call, or remotely 
signaling an answering machine to rewind by holding down a button for a specified amount of 
time.

Direct Station Selection (DSS) Buttons
Any available button on a 10-button or 20-button digital or electronic telephone, add-on module, 
or DSS console can be programmed to provide a direct connection to any other telephone in the 
system. The LED associated with each button serves as a Busy Lamp Indicator that lights when the 
station named on the button is busy. Pressing the DSS button immediately rings the station 
assigned to that button.
Calls made with station DSS buttons forward if the station assigned to the DSS button is in Call 
Forward mode.
Benefits
Provides instant, one-button access to other stations, eliminating the need to repeatedly look up 
extension numbers to place internal calls, and show the status of the extension. This feature 
provides quick communication between two people who work cooperatively, such as an executive 
and the executive’s secretary.

Distinctive LED Indicators
Each line/feature button on a digital telephone has an associated LED. When a button is assigned 
to a CO/PBX line, this LED flashes at different rates to indicate the status of that line.
The in-use flash rate appears on the LED when the line is in use by that station. Other stations 
show a steady LED on that line. The incoming call flash rate appears when a call (internal or CO/
PBX) is ringing in on that line. The on-hold flash rate appears on a station when the station puts a 
call on hold. Other stations show the usual system hold flash rate. The camp-on and busy station 
ringing flash rate appears when an incoming call is camped-on or ringing at a busy station. Other 
distinctive flash rates appear on LEDs associated with a CO/PBX line when that line is on 
exclusive hold, is being recalled from hold, or has a conference call in progress.
When a line/feature button is assigned to a feature, the LED indicates the status of the feature. For 
example, when the “Message Waiting/Flash” button indicates that a message is waiting for that 
station.
LEDs are also distinctive LED indicators with certain dedicated feature buttons, such as Spkr, Mic, 
and Msg. The Spkr LED indicates the on/off status of the speaker or background music. The Mic 
LED indicates the on/off status of the station’s microphone when the station is in Speakerphone 
mode. The Msg LED indicates there is a message waiting.
An LED associated with the DSS button functions as a busy lamp for the station assigned to the 
DSS button.
Digital telephones have dual-color LED indicators. Green indicates CO line or intercom buttons 
you are using. Red indicates use by someone else.
Benefits
Provides quick status of a line or feature by looking at the LED.

Do Not Disturb (DND)
After DND is activated by a station, internal calls and transferred calls do not ring at the station, 
and voice announcements do not come through. Off-hook Call Announce is also blocked. The 
station user can still place outgoing calls, however.
Incoming internal and CO line calls to stations in DND do not ring the station but the DN flashes. 
Incoming CO line callers hear ringing until forwarded or answered by another station. Also, if a 
station is not in DND when an incoming internal and CO line call rings the station, the DND 
button can be pressed during ringing to turn off the ringing at the station, and the caller continues 
to hear ringing until forwarded or answered by another station.
If an internal call is placed to a station that is in the DND mode, and all the appearances of the 
station’s PDN are in-use, the caller hears a fast busy tone. DND can be overridden by any station 
that has the DND Override feature or the Alert Signal button assigned to the DND telephone. 
Incoming CO line callers hears busy tone, unless forwarded or recalled to another station.
If a station is in the DND mode and if the station’s PDN appears on another station as an SDN, the 
callers ring the secondary DNs providing the SDN appearance is idle and the telephone having the 
secondary DN is not in DND. The caller receives ring back tone. If all stations having a particular 
DN (PDN, PhDN, or SDN) are in the DND mode, internal callers receive fast busy tone when 
calling the DN.
DND can be assigned selectively on a station-by-station basis. DND can only be activated by 
electronic telephone or digital telephone stations, not by standard single-line telephones.
Benefits
Improves employees’ time management and productivity by dedicating uninterrupted blocks of 
time to projects or meetings.

Do Not Disturb (DND) Override
After dialing an internal station and receiving a DND signal, a caller with the DND Override 
feature can dial an access code. The called station is signaled with a tone burst, indicating that a 
call is waiting. If the called party has an LCD phone, the number of the calling station is displayed.
This feature can be assigned on a station-by-station basis.
Benefits
Provides convenience and efficient calling by enabling selected users access to stations which are 
in DND. A priority message or announcement is given about important callers or guests.

Dial Pulse/DTMF Mode Change
If the Tone button has been assigned to a station, that station user can change the outpulsing mode 
on the CO/PBX line in use from dial pulse to DTMF with the touch of a feature button.
With some other electronic key systems, DTMF tones are generated only by the Key Service Unit 
(KSU) while an external number is being outpulsed. After that, the tone generator is no longer 
engaged, and the system simply “passes through” the generated electronic pulses. Since these 
electronic pulses are neither rotary nor DTMF, the user is unable to remotely operate any systems 
requiring DTMF tones.
The Tone button on Strata DK systems enables the user to tell the system to switch from rotary 
outpulse to DTMF tone outpulse when required. It also enables users who are in a location served 
by a rotary-only CO to generate DTMF tones for the remote operation of answering machines and 
other devices.
Benefits
Enables users to outpulse DTMF tones at any time. This is especially useful for the remote 
operation of equipment that requires DTMF tones for operation, such as answering machines, 
bank-by-telephone systems, dictation machines, and voice mail systems.

Exclusive Hold
Exclusive Hold enables a station user to put a call on hold so that the call can be picked up at that 
station only or at another station using Directed Call Pickup. No other station can pick up the call 
by simply pressing the DN or the Line button . A distinctive LED flashes indicating that the line is 
on Exclusive Hold.
In order for the feature to work, there must be an appearance of the CO line or DN on the station 
activating Exclusive Hold. To activate, the user presses the Hold button twice. Each system uses 
the feature as follows:
©DK14 – if a DN receives a call while it is on hold, there is no audible or visual indication that 
another call is camped onto the DN. This assumes that there are no idle appearances of the 
DN, which would ring if called while another appearance of the DN is on hold.
©DK40i – if a DN receives a call while it is on hold, there is no audible or visual indication that 
another call is camped onto the DN. This assumes that there are no idle appearances of the 
DN, which would ring if called while another appearance of the DN is on hold.
©DK424 – if a telephone receives a call of any type and the DN that should receive the call is on 
hold, the camp-on tone is sent to that telephone. The camp-on tone consists of two muted ring 
tones three seconds apart.
Benefits
Enhances efficient call handling by providing a way for a station to secure a call on hold. It 
eliminates any annoyance to a caller caused by being accidentally picked up by another party.

Executive Override
Executive Override can be selectively assigned to enable a station user to “break into” a 
conversation of a busy station. Stations with this feature programmed can enter any conversation 
in the system by dialing an access code or by pressing a feature prompting Soft Key. An optional 
warning tone signal is heard through the handset which indicates to the conversing parties that 
another station is about to enter the conversation. After the “break-in,” a three-way conference is 
in effect until one of the parties hangs up.
This feature can be assigned to any station in the system. The maximum number of simultaneous 
Executive Override calls is the same as the number of simultaneous conferences enabled.
Executive Override to any station can be blocked selectively in system programming providing 
security for modem (data) calls, voice mail calls, fax machine calls, etc.
Benefits
Enables selected stations to access a busy station for an emergency or a high-priority message.
