Modem 34336
3.3.5 T EST O PTIONS
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.
3.3.6 EIA O PTIONS
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.
