Black Box 32144 Manual page 163

ENABLE. Enables DTR dialing for
V.25 bis mode.
DISABLE. Disables DTR dialing for
V.25 bis mode.
Analog Loopback Make Busy
All modes
If the Analog Loopback Make Busy
option is enabled, the modem will
provide a busy indication to the
dial-line interface when the
modem is in analog loopback test
mode.
Answer Tone Detection
208, V.32/208 modes
ENABLE. Conditions the
originating modem's receiver
to wait for answer tone detection
before going on-line.
DISABLE. Conditions the
originating modem to go on-line
without requiring answer tone
detection. This setting accom-
modates operation with automatic
calling units that connect the
modem to the line at the end of
answer tone.
Multimode Handshake
Hayes, V.25 bis, Dumb modes
This option determines how long
the modem will attempt to hand-
shake with a V.32 modem before
falling back to a lower speed.
CHAPTER 3: Options: Customizing the Modem Setup
T1 TIMER. If the T1 timer
setting is selected, the modem will
attempt to handshake with a calling
V.32 modem for the time specified
by the T1 Timer option.
V.32 bis ANNEX A. If the V.32 bis
Annex A setting is selected, the
modem will handshake according
to the conventions established in
Annex A of the CCITT V.32 bis
recommendation. Handshaking
using the Annex A selection will
generally be faster than
handshaking based on the T1
timer.
Remote RTS Signaling
Leased line modes (except V.33)
This option provides remote RTS
signaling in asynchronous mode.
When the Remote RTS Signaling
option is on, the state of the Ready
to Send (RTS) signal is transferred
across the modem link (for
diagnostic purposes) without
affecting normal operation. The
Remote RTS Signaling option
allows control over the remote
Carrier Detect (CD) signal as
described below.
Note the following restrictions
for Remote RTS Signaling: The two
modems must be connected at a
data rate of 7200 bps or higher.
The V.13 Operation option must
be off. The DTE-DCE and DCE-
DTE Flow Control options should
not be set to RTS on/off.
