Using the 7400B Plus for
Voice Dialing
Dialing Instructions
This section provides information on how to use the 7400B Plus
for voice dialing.
The 7400B Plus is equipped with a voice dial feature which allows
you to place voice telephone calls from the attached terminal
device. To place a voice call, just tell the 7400B Plus to use pulse
dialing by including the ''P'' dial modifier. (For data calls, tell it to
use tone dialing by including the ''T'' dial modifier.) If you fail to
specify the type of dialing to be used for a call, a data call will be
made.
If you have a speakerphone, the 7400B Plus will normally turn it
on when a voice call is being dialed. You may option the 7400B
Plus to inhibit the speakerphone or delay activating it until after
dialing is complete by setting the appropriate DIP switches. For
more information on DIP switches, see Chapter 2, "Installation."
If your telephone does not have a speakerphone, you may lift the
handset at any time.
Voice calls can be originated from the PC, but you must use the
telephone to hang-up a call.
When a voice call is made using the PC, the telephone number
should be given to the 7400B Plus in a single ''AT'' dial command
as indicated in the example below.
ATD P 9,1 (908) 555-1212
The ''P'' dial modifier must be included to tell the 7400B Plus that
the call is a voice call. If an attempt to dial a voice call is made
using more than one dial command on a command line, the first
dial command will be accepted and the second dial command
may be discarded. After dialing the call, the 7400B Plus
automatically returns to the command mode.
A second voice call can be made from your PC by manually
placing the first call on HOLD, and then entering a dial command
for the second call. Any attempt to dial a second voice call while
the first call is being dialed will be ignored.
Note: On DEFINITY
if you are in directory mode on the telephone, the
procedures are ignored.
On DEFINITY
after you have manually placed the first call on HOLD,
you must select a second call appearance before entering
a dial command for the second call.
