Paradyne 3811PLUS Select Factory Configuration Options, Configuring a Modem Using the SDCP

Select Factory Configuration Options

After the modem passes the power-up self-test, configure it for operation using one of the factory preset configurations.

The 3811Plus modem has several factory preset templates that contain the proper configuration options (straps) for different environments. Modems are shipped from the factory with the Async Dial default configuration options stored in memory. To prepare the modem for Sync Dial, Sync Leased, UNIX Dial, Cellular (Mobile), or Cellular (PSTN), you must change the factory setting, using either the SDCP or the AT command &Fn, as described in the following sections.

The Cellular (Mobile) and Cellular (PSTN) settings (and the analogous AT commands &F5 and &F6) are available only if Enhanced Throughput Cellular (ETC ) is installed.
