10. PROGRAMMING EXTENSIONS
The final step in setting up a DX-80 system is programming the individual extensions.
The DX-80 supports three types of phones:
• DET phones—digital speakerphone with LCD display and 32 programmable feature buttons
• DSS console—digital 60 button device used with associated speakerphone (typically used with the System
Attendant/Administrator’s speakerphone, but can be used with any DET phone in the system)
• SLT phones—independent analog single line telephone devices.
10.1 Overview
While the DX-80 supports SLTs, the majority of features are designed for the DET phone. If you are using SLTs in
a particular system, you must set up the analog ports associated with those SLTs. For details on setting up analog
ports, see Section 10.23,
Configuring Single Line Telephones (Analog Device Support) .
The DET telephones are all equipped with a high-quality, half-duplex speakerphone. This feature makes it pos-
sible to place hands-free calls from any DET telephone.
The DET is also equipped with a 2-row, 16-column Liquid Crystal Display (LCD) to enhance feature operation by
indicating operation status and providing for input based on feature use. The display also facilitates the standard
Caller ID feature – allowing all DETs to receive caller ID information as it is received from the servicing telephone
company. (Caller ID requires a subscription from the servicing telephone company.)
The DET provides three screen-prompt, interactive buttons that simplify feature operation. The bottom row of the
display is used to convey options during normal call processing that allow the user to select from the various
choices. These three LCD interactive buttons take on many different functions, supporting everything from
leaving a callback request to programming the system database.
The following conditions apply to using DET speakerphones.
• The speakerphone function is impacted by environmental conditions.
• Operation of the speakerphone in high-noise areas may yield less than adequate results. If this is the case in
the area where the extension user’s telephone is located, the handset may be used to improve connection
conditions.
• To dial intercom numbers directly from an idle condition, the Hot Key setting should be enabled. Otherwise,
the user must press a programmed intercom button or press the On/Off button prior to dialing the extension
number.
The DET speakerphone also provides the ability to receive incoming intercom calls in Voice Announce Hands-free
mode. When extension users telephones are in this mode, they can reply to an intercom call by using the speaker-
phone.
Extension users may also choose to place their DET phones in Voice Announce - Privacy mode. In this mode, they
can hear the person calling them on the intercom, but their DET phones’ microphones remain muted so the calling
person cannot hear the extension users. Therefore calls may be announced to their extensions while they maintain
a private environment.
In addition to Voice Announce – Hands-free, and Voice Announce – Privacy modes the DX-80 provides a third
mode called Tone Ring mode. When Tone Ring mode is active, the telephone will tone ring whenever an intercom
call is made to that telephone.
