3.3.5TEST OPTIONS

The Test Options affect certain tests (as explained below) but do not activate tests.

The DSR During Analog Loopback is available for all modes. When ON is selected, the Data Set Ready signal is forced on when the modem is in the analog loopback test mode. In general, this option should be left ON (the default selection).

The Remote Test option is available for all modes. The Remote Test option allows you to prevent tests from being initiated on the local Modem from a remote modem. If DISABLE is selected from the Remote Test screen, the local Modem ignores test initiation signals from a remote modem. If ENABLE is selected, tests can be initiated from a remote modem.

Note that there are two REMOTE TEST screens. One is for the option just described; the other is used for selecting either the remote digital loopback tests or remote front panel control. The Remote Test option screen (for preventing or allowing remote testing) looks like the one shown below.

3.3.6EIA OPTIONS

The seven options described below allow control over specific EIA interface signals.

The CTS to EIA options are available for all modes. Regardless of the setting selected for this option, Clear to Send (CTS) is off during flow control (which occurs if error correction and flow control or buffer mode are enabled).

•NORMAL — The Clear to Send signal is on while the modem is on-line.

•RTS — The CTS signal immediately follows the RTS signal with no delay.

•TRUE — The CTS signal follows DTR.

CTS can also be set to be ON at all times regardless of DTR by using the Summary Setup feature. However, if CTS on/off is selected from DCE-DTE screen 1, V.42 flow control, while active, overrides the CTS ON selection. To set CTS ON, refer to Appendix C. Note that if you set CTS to ON using Summary Setup and then make a selection from the CTS to EIA screen, that selection cancels the Summary Setup CTS ON selection.
