Selecting Factory

Configuration Options

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

The 3800Plus modems have several factory preset templates that contain the most commonly used configuration options (straps) for Asynchronous Dial, Synchronous Dial, Synchronous Leased (Answer or Originate), UNIX hardware network, cellular mobile, and cellular PSTN configurations. Your modem is shipped from the factory with the Async Dial default configuration options stored in memory. If Sync Dial, Sync Leased, UNIX Dial, or Cellular is more appropriate for your configuration, then you must change the factory setting using either the modem's DCP or the AT command set as described in the following sections.

The preset configuration gives you a ªhead startº in getting your modem operating and reduces the amount of time required to configure your modem. For a better understanding of DCP operation and factory preset configuration options, refer to Chapter 8, Configure Branch.

Using the Diagnostic Control Panel (DCP)

The DCP's liquid crystal display (LCD) consists of two

16-character lines which display modem status, control functions, and configuration options as well as indicating your location in the Top-Level menu tree (Appendix A).

To change the factory template using the DCP, perform the following steps:

1.On the DCP press the key until Configure comes into view.

2.Press the function key below Configure to select the Configure branch.

The LCD now displays Ld EditArea frm.

3.Press the key until Factory comes into view, then press the F1 key to display the factory preset configurations.

Factory preset configurations are Async Dial, Sync Dial, Sync Leased, UNIX Dial, Cellular (Mobile), and Cellular (PSTN). If Sync Leased is selected, you must choose either Answer or Originate mode.

4.Press the key until the appropriate factory preset appears on the LCD, and press the corresponding function key to select your choice.

5.Choose Function appears and displays the Edit and Save functions.

6.Press the F3 key (Save) to save the new factory preset configuration to one of three configuration areas, Active (Saved), Customer 1, or Customer 2.

(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.)

The LCD now displays Sav EditArea to.

7.Press the key until the appropriate configuration area appears on the LCD, then press the corresponding function key to select your choice. (Saving configuration options to the Active (Saved) configuration area automatically saves them to the Active (Operating) configuration area.) The LCD displays Command Complete.

8.The modem is now configured with the selected

factory template. Press the key to return to the Top-Level menu.

Refer to Chapter 8, Configure Branch, for more information regarding default factory configuration options.

Using AT Commands

When using AT commands, the following criteria must be met:

•Make sure the asynchronous DTE's communication software is configured for 10-bit character format (for example, 8 data bits, no parity, and 1 stop bit).

•Make sure the DTE (RS-232D) cable is attached to the DTE connector on the rear of the 3810Plus or 3820Plus modem, or (for the 3811Plus modem) the rear of the COMSPHERE 3000 Series Carrier, and the correct serial communications port on the asynchronous DTE.
