DataTalker Owner’s Manual
The Dial/Leased option selects the type of connection to the telephone company. If the data line
provided by the telephone company is a dial-up line, then you must select the dial option. The
options are Dial and Leased with the default being Dial.
The 2 or 4 Wire option selects how the MMH2834 modem is connected to the telephone line.
E.g., if the telephone company is supplying a 4-wire lease, select the 4 Wire option. The options
are 2 Wire and 4 Wire, with the default being 2 Wire.
The Answer/Originate option selects the line frequency used when leased line operation is
selected. When dial operation is selected, it enables or disables auto answer. For leased line
operation, one MMH2834 modem should have Originate selected and the other MMH2834
should have Answer selected. For dial operation, select Answer if the MMH2834 needs to answer
an incoming call.
The Transmit Level option selects the output transmission level in decibels. The options are 0
and -10db, with a default of -10db. The closer the transmit level is to zero the greater the level
(strength) of the output signal. This option should only be changed under the direction of Multi-
Tech Tech Support personnel.
The Dial On Demand (DOD)/Disconnect On Inactivity (DOI) option drops DTR to the
MMH2834 modem to disconnect if the inactivity timer has expired and raises DTR to reconnect if
the voice/fax or data channel goes active. The default is to have the DOD/DOI option turned off.
If this option is off, options 9 and 10 do not appear on the menu.
The Disconnect on Inactivity (DOI) Timer option signals the MMH2834 to hang up the
composite link by dropping DTR to it when the timer expires. When the DOI Timer option is
selected, a submenu is displayed in which you can enter the number of minutes that the inactivity
timer is set for. The range of the timer in minutes is 01 to 99. The default setting for the timer is
three minutes.

The Dial On Demand (DOD) Toggle DTR option activates the DTR Toggle Timer. When activity
on the voice/fax or data channels cause DTR to go high telling the MMH2834 modem to DTR
dial, this timer is started. If the connection is established before this timer expires, the timer is
stopped. Otherwise, when the timer expires, DTR is toggled to tell the MMH2834 to dial again
and this timer is restarted. The default is 40 seconds.
