6.0 V.25 bis Autodialer
6.0 V.25 bis Autodialer
For international compatibility, the Modem can 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.
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. You can 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.25 bis autodialer can be enabled by either using the Quick Setup
feature, or selecting one of the Dialer Mode options.

Three Quick Setup configurations are available for 2-Wire Dial (V.25 bis).
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 synchro-
nous, bit-oriented operation) on the LCD, and then press push-button 2.
After selecting the desired V.25 bis Quick Setup configuration, you can reset
individual options to suit your application (see Chapter 2).

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.)

If you enable the V.25 bis autodialer using the Dialer Mode option, no other
options are changed. Select DIALER from SETUP screen 2. Then, press the
right arrow pushbutton to go to the DIAL V25 bis screen (screen 2). Select
the V.25 bis data protocol appropriate for the DTE to be used: asynchronous
(Asyn); synchronous, character-oriented (Syn_c); or synchronous, bit-
oriented (Syn_b).
