Selecting Factory Configuration Options
After the modem passes the power-up self-test, it can be configured for operation using
one of two factory preset configurations.
These factory preset templates contain the most commonly used configuration options
(straps) for Asynchronous Dial and UNIX hardware network configurations. Your
modem is shipped from the factory with the Async Dial default configuration options
stored in memory. If UNIX Dial is more appropriate for your configuration, then you
must change the factory setting as described as follows.
NOTE:
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
Recovering AT Commands
for these procedures.
Procedure
To change a factory template:
1. Use the AT&F&W command to load the appropriate factory configuration to the
appropriate storage area. Enter the following:
Type:
AT&F
y
&W
n
where:
y
is one of the following factory configurations:
0 = Async Dial
3 = UNIX Dial
5 = Cellular (Mobile) (Valid only if ETC is installed)
6 = Cellular (PSTN) (Valid only if ETC is installed)
where:
n
is one of the following configuration areas:
0 = Active (Saved)
1 = Customer 1
2 = Customer 2
NOTE:
These three configuration areas are nonvolatile memory locations. Active (Saved)
contains the most recently saved changes to any configuration options. In the
event of power loss, the modem retrieves these configuration options. Customer 1
and Customer 2 are user-defined configuration areas.
2. Press Enter. The selected factory configuration is saved.
NOTE:
When configuring your modem, keep a record of its configuration options as a
future reference in case the modem must be replaced.
