F3
If a failure occurs during the self-test, the LCD displays Power On Selftst Failed for several seconds. The LCD
then displays the Top-Level menu screen with the message Power on Fail appearing on the top line of the LCD.
Although a failure has occurred, the modem will attempt to operate. This allows you to activate a more thorough
self-test using the Test branch. Refer to the Test Branch section in Chapter 3 of the Technical Reference Manual.
Selecting Factory Configuration Options
After the modem passes the power-up self-test, configure it for operation using one of the six factory preset
configurations.
The Model 392xPlus modems have six factory preset templates that contain the most commonly used
configuration options (straps) for Synchronous Leased (Answer or Originate), Asynchronous Leased (Answer or
Originate), Trellis Multipoint (Control or Tributary), Asynchronous Dial, Synchronous Dial, and UNIX Dial
hardware network configurations. Your modem is shipped from the factory with the Synchronous Leased
(Answer) default configuration options stored in memory. If Synchronous Leased (Originate), Asynchronous
Leased (Answer or Originate), Trellis Multipoint (TMp) (Control or Tributary), Async Dial, Sync Dial, or UNIX
Dial is more appropriate for your configuration, then you must change the factory setting using either the
modem’s DCP (as described in the following sections) or the AT command set.
The purpose of having preset configurations is so that you can have a “head start” in getting your modem
operating and reducing the amount of time required to configure your modem. For a better understanding of DCP
operation and factory preset configuration options, refer to Chapter 4, DCP Configuration, in Technical Reference
Manual.
