Directory Number [DN] Buttons

Directory Number [DN] Buttons
These are the telephone’s call buttons, used to originate and receive internal and external calls. See
“Multiple Directory Numbers” on Page 82 for information on the different types of [DNs].
DISA Security Code Revision
Certain digital telephones selected in programming can revise the DISA security code.
Distinctive LED Color and Flash Indications
♦ Outside CO /LQH and [DN] button LEDs light red or green to help digital telephone users
determine the status of calls. Electronic telephone LEDs are always red when they light.
♦ Digital and electronic telephone LEDs flash at varying rates to indicate calling status.
Distinctive Station Ringing
Digital and electronic telephones can have one of three different ring tones for incoming CO and
DID line calls to help distinguish incoming calls. Also, ring tones for transferred CO and DID line
calls are different from the ring tones of direct CO line calls to the same telephone.
Do Not Disturb (DND)
Station users with digital telephones can activate DND to prevent any calls from ringing them.
Callers will hear a fast busy tone. If a DND station’s [DN] appears on other telephones, callers will
ring the [DNs] on those other telephones. The [DN] will then flash on the DND station, but it will
not ring. Stations in DND mode can originate calls. Also, Call Forward-Busy will operate on a
DND telephone, even if the telephone has idle [DNs].
Do Not Disturb (DND) Override
Stations with this special feature programmed can override stations in the DND mode with a tone
that indicates that somebody is trying to contact them.
DP/DTMF Mode Change
This feature allows digital and electronic telephone users to change the line out-dialing signal
mode from Dial Pulse (DP) to DTMF with the touch of a feature button.
Exclusive Hold
Exclusive Hold enables a digital telephone user to place a call on hold so that the call can only be
picked up at that station or at another station using Directed Call Pickup. No other station can pick
up the call by simply pressing the [DN] or line button that the call is being held on.
