7.5 How to Select and Activate Tests

7.5.1FRONT-PANEL CONTROL

Tests are accessed and activated in the same way options are selected: by using the LCD and front panel pushbuttons (as explained in Chapter 3). To find the LCD screen for a specific test, refer to the LCD flow chart (Diagnostic And Control Functions) at the end of this manual. Once you access the screen for a specific test, press pushbutton 1 to begin the test (select ON). A test status screen is automatically displayed. To deactivate a test, press the ENT pushbutton and then pushbutton 3. (The ENT button cannot be used to exit the text screen until the test is deactivated.)

NOTE

For valid test results, error correction must be disabled before diagnostic tests are run. To disable error correction, set the V.42 Mode option to OFF.

7.5.2RUNNING TESTS IN HAYES MODE

In Hayes emulation mode only, most of the diagnostic tests available on the Modem can be activated via the DTE keyboard using the &T commands listed in Chapter 5. To set the duration of a test, assign a value to register S18. For example, AT S18=30 sets the test time to 30 seconds. The command &TO terminates a test. For further information, see Section 5.2.

7.5.3REMOTE TEST CONTROL

You can configure the Modem to ignore or accept requests from remote modems to initiate tests on your Modem. To access the remote-test control option, select TEST from SETUP screen 4. Then, select RMT from the TEST OPTIONS screen. From the REMOTE TEST screen, select ENABLE to allow remote test initiation or DISABLE to refuse remote test requests.

7.6 Diagnostic Monitoring: Status Screens

To obtain additional information about the status of the communications system, observe the status screens described in the following sections. To view these screens, push the ENT button until the EIA status screen appears. Use the right arrow pushbutton to advance to other status screens.

7.6.1EIA STATUS SCREEN

The EIA status screen indicates the operational status of the modem and the condition of certain EIA RS-232 leads. The abbreviations that appear are identified below; however, only a few of these abbreviations are displayed during actual operation.
