Data Modules
21-22 Issue 11 December 1999
M9/F25 Adapter, an adapter which allows connection from a 9-pin jack to a 25-pin
jack. A DCP interface (using a D8W-type modular telephone cord) is used to
connect the 8400B Plus data module to the digital PBX.
The 8400B Plus data module may be optioned for use either with or without a
telephone. In the stand-alone case, the 8400B Plus data module supports data
service only. Otherwise, the 8400B Plus data module provides simultaneous data
and voice service. The 8400B Plus works with all DCP voice terminals that
support 2-wire operations (such as the 8400-Series voice terminals), to provide
simultaneous data and voice service.
The voice dial feature allows you to dial a voice call without touching the
telephone. Depending on your communications package, you may also store
telephone numbers on a PC and recall them for dialing, log phone calls for easy
billing, and take notes for later reference during a telephone conversation. In
addition, the 8400B Plus data module can be used to automatically turn on the
speakerphone of the voice terminal when a voice call is dialed from your terminal
device.
Figure 21-6 shows a standard configuration in the United States, using a
telephone and separate power supply. Figure 21-7 shows a standard international
configuration using a telephone and separate power supply. Both the US
configuration and the international configuration may be installed using a closet
power supply as shown in Figure 21-8. This last installation eliminates the need
for the separate power supply.
