Digital Telephone Upgrade Options
Digital telephones can be upgraded with the following options.
Digital Add-on Module (DADM)
The DADM adds 20 feature buttons to DKT2000-
series telephones. These feature buttons can be
assigned for CO line access, DSS, and Station or
System Speed Dial. Directory Numbers or other
functions, however, cannot be assigned to DADMs.
Up to two DADMs can be attached to a telephone to
provide 40 buttons to supplement the telephone’s 10
or 20 buttons.
♦ DK14 supports up to eight DADMs
♦ DK40i supports up to 12 DADMs
♦ DK424i supports up to 200 DADMs (see
Table 40 on Page 109 for the capacities of
different common control units)
Integrated PC Interface (RPCI-DI)
An optional RS-232 PC interface unit that replaces
the normal telephone base and provides the
telephone with simultaneous computer-telephone
interface and voice/data features, without the need
of a modem or an extra outgoing line.
RPCI-DI-equipped digital telephones can also be
connected to a PC with Microsoft
®
Windows
®
TAPI applications. TAPI, or Telephony Application Programming Interface, applications enable
the DK to provide “pop-up” screens on a PC that show information on the Calling or Called party.
Information such as ANI, DNIS, and Caller ID data is sent from the digital telephone/RPCI-DI to
provide information for “pop-up” screens to the computer. The Telephone Service Provider
Interface (TSPI) PC software is included with each RPCI-DI. For details on data interface
specifications, see Table 51 on Page 129.
Digital phones shared with the Cordless DKT-2004-CT telephone cannot use the RPCI.
Headset/Loud Ringing Bell Interface (HHEU)
The HHEU provides interfaces for both a headset and a loud ringing bell speaker. The headset
must use a carbon microphone. (With the loud ringing bell feature, the speaker amplifies the
ringing or voice announcement of an incoming call.) For details on data interface specifications,
see Table 49 on Page 128.
Microphone Unit (RFDM)
The RFDM1A is an external microphone that connects to the DKT2020-FDSP. This enables users
to select a setting that provides the clearest transmission for a particular environment. In addition,
the DKT2020-FDSP has three operational modes for enhanced microphone operation. See
“Microphone (External Unit)” on Page 105 for more information.
