tion times at these data rates, even with higher noise, resulting in improved effi-
ciency of the shared STDMA channel. Since signal lock is faster at higher data
rates, BFAT is not active above 256 kbps.
Entering A at the command prompt will toggle this feature On or Off.
This feature requires Router firmware version 1.5.3 or later. The unit configura-
tion must be set for operation at either 3/4 QPSK or .95 QPSK in order to utilize
BFAT.

Burstmap Multicast IP

This menu item is used to define the IP address for the Burstmap Multicast that
is sent out by the STDMA burst controller at the Hub to all of the associated
remotes in that group. This address must be the same for all members of the
goup. The burstmap is a proprietary message sent from the Hub to all remotes,
at regular intervals, specifying the relative start time and duration for each
terminal to transmit.
To change the current address, enter N at the command prompt to display the
dialog shown in figure 3-11.

Outbound IP

This menu item, which appears for all Hub configurations, displays the current
Outbound IP address. This specifies the Hub device that is supplying the TDM
outbound to the satellite (typically a CDM-570L). Specifying this address is
necessary for Hub configurations that utilize a burst controller (such as the
CDD-56X) that is a separate device from the TDM modem.
This address must also be defined when the DPC feature is to be used. The
Outbound IP address will be the same as the burst controller IP address when
the burst controller and the TDM modem are the same device.
To define the TDM outbound address, enter O at the command prompt to
display the dialog shown in figure 3-12.
