Predefine data options profiles. Some programs include completely defined data option profiles (also called configuration profiles) for popular modems. If available, select the options profile for the Hayes® Smartmodem 2400™.

Command files. These files, also called script files, allow you to define a group of commands that may be executed for automatically logging into specific remote devices.

Appendix C, “Application Notes,” provides guidelines for using a few of the more popular communications software packages with the 7400B Data Module.

Selecting DCP Cords The 7400B Data Module is supplied with a 5-foot D8W cord. Use this, or obtain the appropriate length D8W telephone cord for DCP connection between the 7400B Data Module and the PBX wall jack. If you are using the with-telephone option, you will need a second D8W telephone cord to connect between the data module and your telephone or voice terminal.

Selecting DIP-Switch Options

Three hardware options may be selected by setting switches on an internal 8-position DIP switch (SW1). These options are described here, and procedures for setting the switches are provided in a later section titled “Setting the Hardware Option DIP Switches.”

With/Without Telephone Option (SW1-1)

When this option is set for operation without an associated telephone (SW- 1 set to " WITHOUT PHONE"), the 7400B Data Module offers only data service between a terminal device and a remote system.

Setting this option for operation with an associated voice terminal (SW- 1 is set to “WITH PHONE”) enables simultaneous data and voice service over the same line from the PBX.

When the 7400B Data Module is optioned for “WITH PHONE,” an AT&T 7400-series DCP digital voice terminal is connected to the data module only for its voice service features; data service is provided directly from the 7400B Data Module, and any data features that the voice terminal may offer cannot be used.

Note: A change in the setting of this option becomes effective when the data module is powered on after being powered off. The setting of this option cannot be changed arbitrarily—it must agree with how the line is administered at the PBX. For information on how to administer the 7400B Data Module at the PBX for use with or without a telephone, refer to Appendix C, “Application Notes.”
