3 Getting Started
This chapter covers basic details of how to set up your modem in a straight-
forward environment: how to control the modem from your DTE, and how
to use the AT command language to make a call whilst the modem is in its
default condition.
3.1 Starting Up
Before using the modem, ensure that it has been installed correctly as
described in Chapter 2.
The factory default is configuration 0 (described in Section 4.1). As this is
suitable for many uses on PSTN lines, you may not need to reconfigure the
modem. If this is so, follow the procedure below, checking that the modem
and command terminal (which may be the data DTE) respond as indicated.
1. Switch on the DTE and the command terminal.
2. Switch on the modem. The LED indicators on the front panel will reflect
the status of the DTE interface.
TXD
,
RXD
and
OH
should be off.
3. Load the default factory configuration 0, as follows. Make sure all the
buttons on the modem's front panel are OUT. Press the
LOAD
(
L
) button,
press and release the
ENTER
(
|
) button, then release the
LOAD
(
L
) button.
4. Type the command AT on the command terminal keyboard and press
RETURN
. The message OK should be displayed on the screen.
If factory configuration 0 is not suitable for your operation, go to Chapter 4
to choose a more suitable configuration, and repeat the procedure above,
using the buttons shown in Table 4-1 during step 3.
For example, to load configuration 10 (for a leased line), ensure that
buttons
2
and
DIAL
(
D
) are in, and that all other buttons are out, before
pressing
LOAD
(
L
). After pressing
ENTER
(
|
), release
LOAD
(
L
),
2
and
DIAL
(
D
).
