PERATION
When the modem is operating in
Dumb mode or configured for Bell
208 operation, data calls may be
manually originated from a phone
set. (Plug the phone into the
modem jack marked "PHONE.")
For manual-originate operation,
the remote modem may be
configured for either automatic or
manual answer. For manual-
originate/answer operation, one
modem must be set to ANSWER
and one must be set to
ORIGINATE via the ANS/ORG
DEFAULT screen. For either type
of operation, use the Quick Setup
to configure the modem. (The
Dumb mode Quick Setup defaults
to asynchronous operation; the Bell
208 and V.32/208 Quick Setups
default to synchronous operation.)
Any of these three Quick Setups
will set the modem to originate
mode. If you want to set your
modem to answer mode, use the
front panel controls to access the
ANS/ORG DEFAULT screen
(MODEM SETUPS screen 4). Then
select ANSWER (answer mode).

Originating a Data Call Manually
To manually originate a data call,
select TALK from MAIN MENU
screen 1. The MANUAL-DIAL
screen will now be displayed. Select
TALK again. This puts the modem
in talk mode. Lift the handset and
listen for the dial tone. Dial the
phone number of the remote
modem.
When you hear a high-pitched
answer tone, select DATA from the
MANUAL-DIAL screen, and place
the handset back on the cradle.
The LCD will display the status of
the communication. Typically it will
appear as follows:
D TR
9600
The data link between the two
modems is now established, and
data transfer can begin.
