Dial Tone You will normally hear continuous dial tone when you lift the
handset. You will hear discriminating dial tone (also called
interrupted dial tone) or transfer dial tone under certain conditions.
Dial Tone - Outgoing Calls The system can provide a pseudo-CO dial tone to prevent possible
confusion to station users.
Dialed Number Editing Dialed Number Editing lets you edit numbers during dialing.
Dialing - Conflicting Numbers
The system can differentiate between conflicting numbers such as
1-0-0-0-0 and 1-0-0-0. In this example, if the 5th digit is not dialed
within a time-out period, the system assumes that the dialed
sequence is complete and makes the call.
Direct-In Lines (DIL) Direct-In Lines (DIL) allow incoming trunks to be assigned to a
specific station or hunt group so that calls from the trunk ring the
station or hunt group directly.
Direct Inward Dialing (DID)
Direct Inward Dialing (DID) allows incoming calls on designated
trunks to directly access predefined stations (or other answering
points) on the system.
Direct Inward System Access
(DISA)
Direct Inward System Access (DISA) lets external callers access
the system by using a special trunk. The system sees the DISA
trunk as a station with its own Class of Service and Class of
Restriction. Calls that enter the system on DISA trunks have
access to a variety of system features. In all cases, the DISA trunk
can be assigned account codes to provide a high degree of
security or additional options.
Direct Outward Dialing (DOD) Direct Outward Dialing (DOD) lets you make external calls without
the assistance of the attendant.
Direct Page Direct Page allows you to page another telephone over its built-in
speaker.

Direct Station Select/Busy
Lamp Field (DSS/BLF)
A Busy Lamp Field (BLF) allows the status of a directory number to
appear on the line status indicator of a telephone or Programmable
Key Module. The monitored device may be on the same system or
another system within the same cluster. The key associated with
the busy lamp acts as a Direct Station Selection (DSS) key.
Display Contrast Control Display Contrast Control lets you adjust the contrast of the
alphanumeric display.
DNI Allows the programming of Mitel Networks digital devices
Do Not Disturb Do Not Disturb (DND) lets you place your set in an apparent busy
condition without affecting the outgoing functionality. If someone
calls your set while DND is activated, he or she will hear special
busy tone.
DTMF Keypad Support DTMF Keypad Support lets ONS/OPS extensions use all 16 keys
on a 4x4 DTMF keypad. The additional row of four keys (ABCD) is
used to access features in the system.
