modems.
DUMB MODE and BELL 208 OPERATION
Bell 208 operation is available on all models except the ALX V.32 and ALX V.32M.
For additional information on dumb mode, see Chapter 1. For additional Bell 208 information,
see Chapter 1 and the
Communication Standard
section in Chapter 2.
Both modes: For information on storing and autodialing phone numbers, see
Front Panel
Autodialing
earlier in this chapter. For dialing parameters that can be used to modify dialing
operations, see Table 4-2.
Manual Originate / Answer Operation
When the ALX 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/answer operation, configure the remote modem for automatic or manual
answer. Use the dumb mode, Bell 208 or V.3x/208 Quick Setup to configure the modem. (The
dumb mode Quick Setup defaults to asynchronous operation; the Bell 208 and V.3x/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 ALX will
display the MANUAL-DIAL screen. Select TALK again. This puts the ALX in talk mode. Lift
the handset, listen for the dial tone, and 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 displays the status of the communication;
typically it will appear as follows:
The data link between the two modems is now established, and data transfer can begin.
