Dumb mode is used primarily for manual call origination, answer-only
applications, and in conjunction with certain dial back security systems that
utilize MI/MIC signals to place the modem on-line. (If you need to configure
the modem for MI/MIC use, refer to Appendix D.) For additional
information on Dumb-mode operation, refer to Chapter 4.0, General
Operation and Special Features.
Answering a Call Automatically. After the Quick Setup for 2-Wire Dial
(Dumb) mode is selected, the Modem will automatically answer incoming
calls. The only other requirement is that either (1) the DTE must provide
the DTR signal (TR on the LCD status screen) to the modem, or (2) DTR
must be set to TRUE (using the modem’s DTR from EIA option screen).
Originating a Call from the Front Panel. Before you can originate a call from
the front panel, you must store the number to be dialed in the modem.
From the Set-up <5> screen, access the PHONE screen by pressing the
following pushbuttons in sequence:
Pushbutton 1 (Phone)
Pushbutton 2 (Prog)
The abbreviations DEC, CTRL, and INC are displayed on the bottom line
of the LCD, indicating that you located the PHONE screen.
Follow the steps below to store the phone number:
1. Use the right and left arrow pushbuttons to go to the digit you want to
change. The cursor causes the character at that digit location to blink,
indicating that the digit or character can be changed.
2. Use pushbutton 1 to decrease numbers, and pushbutton 3 to increase
them.
3. Use pushbutton 2 (CTRL) to sequence through the dialing control
characters (explained in Chapter 3).
4. Use the arrow pushbuttons to move on to the next digit or character
you want to change. (The characters that can be stored are listed in
Chapter 3.)
5. The phone number is saved when you return to the MAIN MENU.
To return to the EIA status screen, press ENT three times.
