Mitel SX-2000 - Manual (Page 165)

Feature Description
50003510 Revision A 151
Direct Trunk Select calls bypass the system’s Automatic Route Selection feature and are
therefore unaffected by COR (toll control). The user can enter an account code while in an
established call.
Disconnect Alarm
This feature serves as a security feature by turning on an alarm when a SUPERSET telephone
is unplugged.
Display Caller ID on Non-Prime Lines
Prior to LIGHTWARE 19 Release 2.0, users manually identified the caller ID on ringing
non-prime lines with the use of the SUPERKEY on their display telephone. Now, set users can
automatically see the caller ID on non-prime lines.
Display Keys
This feature allows users of SUPERSET display telephones to display the function of certain
keys on their sets.
Do Not Disturb (DND)
The Do Not Disturb feature allows a telephone user to block incoming calls from ringing the
telephone. It also prevents incoming Directed and Group Paging announcements from
occurring over the set speaker. Outgoing calls are not affected.
Callers to a telephone with Do Not Disturb active receive reorder tone. The message DO NOT
DISTURB appears on display sets. The system can be programmed to reroute such calls to a
predetermined answering point. Consoles and SUPERSET 4150, SUPERSET 430, and
SUPERSET 4DN telephones can override Do Not Disturb when COS 500 (Override) is enabled,
provided that COS Option 238 (Override Security) is disabled in the called set.
DTMF-To-Rotary Dial Conversion
This feature automatically converts DTMF tones from DTMF equipment to rotary dial outpulsing
on outgoing trunks that have been programmed as rotary dial trunks.
Emergency Call Handling
This feature allows you to remove call blocking for emergency calls by designating digit strings
(for example; 911 or 8888) as emergency calls in ARS programming.
Emergency call handling ensures that an emergency call is allowed for all stations. Exceptions
include Hotline telephones or Receive Only sets. Conditions are listed in the Program Feature
description for Emergency Call Handling. Because you define the emergency call digits defined
in ARS and Toll Control, emergency call handling is not restricted to 911 calls. This permits
emergency call handling in areas where 911 service is not available or where the emergency
code is another set of digits.
