Modem Power-Up

Once your modem is properly connected to the DTE,
dial or leased lines, and ac outlet, press the modem's rear
panel power switch to the ON position. The modem
begins a power-up self-test in which all front panel LEDs
momentarily light (note that this also occurs on a reset of
the modem), and the Power LED remains ON. The state
of other LEDs depends on your modem's configuration.
See Table 1-1 in Chapter 1.
On initial power-up, the modem is in Command mode.
To verify that the modem is connected and functioning
properly, enter the following:
TYPE: AT
PRESS: Enter (Return)
The screen displays OK.
If the modem does not return OK, refer to
Appendix B, Troubleshooting.
Selecting Factory
Configuration Options
After the modem passes the power-up self-test, it can
be configured for operation using one of the factory preset
configurations.
The purpose of preset configurations is to simplify the
customization your modem.
These factory preset templates contain the most
commonly used configuration options (straps) for
Asynchronous Dial, UNIX Dial, and Cellular
configurations. Your modem is shipped from the factory
with the Async Dial default configuration options stored
in memory. If UNIX Dial, Cellular (Mobile) or Cellular
(PSTN) is more appropriate for your configuration, then
you must change the factory setting as described as
follows.

If you have already changed
certain configuration options, you
may have lost AT command
control. For example, operating in
Synchronous mode or disabling AT
commands results in an inability to
change configuration options. To
regain AT command control, refer
to the Recovering AT Commands
section for these procedures.
To change a factory template, perform the following
steps (for more information on changing factory templates
using AT commands, refer to Chapter 4, AT Commands
and S-Registers).
