If you are using your MultiAccess as a network modem pool, you will need to set up the Modem Usage menu to
support your configuration.
1. Click on the Usage drop down arrow and chose the Modem Sharing – authentication type that suits your
applicational needs.
2. Click on the Modem drop up or down arrow and select the tty modem(s) for modem sharing. You can choose
multiple modems by holding down the shift key.
3. When the Modem Usage is set to Modem Sharing, the following options become available:
Display Called Number - This parameter applies to inbound (received) calls when the Line Interface type is
PRI. The telephone number (or final digits) dialed by the originator will be displayed into the telnet socket
following the first “ring” message. The Called Number information (string of digits) is provided by the central
office switch and is commonly referred to as DNIS. The MA30120 does not support DNIS when the Line
Interface type is T1-RBS.
Reverse Dial - This parameter enables two features, comma dialing and reverse dial mode. When enabled,
the dial string can include the use of commas, used to create a pause between digits of the dial string (most
commonly used to specify the extension of the answering modem).
Example: “atdt18003334444,,,,,4321”. Each comma creates a 2 second pause. 4321 is the extension of the
desitination phone line\modem.
Reverse dial mode is where the dial string includes the letter “r” at the very end of the dial string, the purpose
of which is to instruct the MA30120 modem to switch from originate to answer mode after dialing. For
example: “atdt17637175549r”.
Please Note: When Reverse Dial is enabled, the dial string must include the tone (t) command, for example,
atdtstring .
