Dial Back Up
The unit offers two methods of providing an alternate data path in cases where the
DDS network connection fails. These are an internal 33.6 modem or an external
device, synchronous or asynchronous, which is compatible with a switched circuit
technology. The 10-pin modular DBU port provides the access for either method.

DISABLE - Does not allow the unit to respond to a dial backup situation.
ENABLE - Allow the unit to respond to a dial backup situation.
DAILY - Allows the unit to respond to a dial backup situation only during the
specified time period for that day. Selecting this option causes the Daily Periods
configuration field to be activated at the end of the Scroll menu. See Daily Periods
on page 25 for configuration information.
ACTIVATE - Forces the unit to place a call and switch to the dial backup device.
DBU Activator. Used to select the criteria that the unit will use to activate the dial
backup sequence. The choices for the Dial Backup Unit Activator are LOS, OOS,

terminal adapter is used. If DBU format is Sync, this field only applies during the
configuration and dialout process.
