Dial Tone
You will normally hear continuous dial tone when you lift the
handset. You will hear discriminating (also called interrupted), 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 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 fifth 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) 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) Permits incoming calls on designated trunks to directly access
predefined stations (or other answering points) on the system.
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) Lets you make external calls without the attendant assistance.
Direct Page Allows you to page another telephone over its built-in speaker.
See Off-Hook Voice Announce.
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 Lets you adjust the contrast of the alphanumeric display on your
phone.
DNI Allows the programming of Mitel Networks digital devices
Do Not Disturb
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 a special busy tone.
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.
Emergency Services Allows an Emergency Services number to be dialed, which sends a
Customer Emergency Services ID (CESID) from the system to the
Public Safety Answering Point (PSAP). The CESID is used as a
key in the Automatic Location Information (ALI) database to
retrieve a database record indicating the precise location of the
caller.
Feature Keys Let you activate features without dialing feature access codes.
Flash -Calibrated Provides an alternate method of generating a Switchhook Flash.
