CHAPTER 6: V.25 bis Autodialer
6. V.25 bis Autodialer
6.1.1 Q

ETUP
Three Quick Setup configurations
are available for 2-wire dial V.25 bis
operation. Selecting any of the
three V.25 bis Quick Setups (via
QUICK on SETUP screen 1)
enables the V.25 bis autodialer
and causes all modem options to
be automatically set to a preset
configuration. Each V.25 bis Quick
Setup is suitable for a typical V.25
bis application, depending on the
DTE to be used.
To select a 2-wire dial V.25 bis
Quick Setup, access QUICK SETUP
screen 2, 3, or 4 (for asynchronous;
synchronous, character-oriented;
or synchronous, bit-oriented
operation, respectively) on the
LCD, and then press pushbutton 2.
After selecting the desired V.25 bis
Quick Setup configuration, you can
reset individual options to suit your
application, if desired, as explained
in
Chapter 3 .
In accordance with the CCITT
V.25 bis Recommendation, the
modem V.25 bis asynchronous
Quick Setup sets the character
length to 10 bits, including 1
even parity bit. Both V.25 bis
synchronous Quick Setups set
the modem for odd parity. (For
synchronous operation, the
character-length option setting
has no effect.)
For international compatibility,
the modem can be configured to
function as a V.25 bis autodialer.
In V.25 bis mode, the modem
is compliant with CCITT
Recommendation V.25 bis, an
internationally recognized standard
for serial automatic call origination
and answering.
The V.25 bis autodialer uses the
dialing command set defined by
the V.25 bis Recommendation. It
allows you to store and dial phone
numbers from the DTE in both
synchronous and asynchronous
applications. You can dial numbers
directly or you can instruct the
modem to automatically dial a
previously stored number.
6.1 Enabling the V.25 bis Autodialer
The V.25bis autodialer can be
enabled in either of two ways—by
using the Quick Setup feature or
by selecting one of the Dialer Mode
options.
