group. 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 3-10.

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-570/570L). Specifying this address is
necessary when configuring a Hub that utilizes a burst controller that is a sepa-
rate device from the TDM modem.
To change the target address of the TDM outbound for DPC messages for the
STDMA controller, enter O at the command prompt to display the dialog shown
in figure 3-11.

Cycles Per Burst Map

This menu item, which appears for all Hub types except Dynamic Cycle and
GIR, displays the number of spin cycles that occur prior to each broadcast of the
burstmap. This parameter can be modified from the Hub CDM-570/570L by
entering a C at the command prompt as shown in figure 3-12. For Dynamic
Cycle and GIR configurations, the number of cycles is automatically set to one
in order to ensure optimum performance for these Hub types.
On Remote units, this menu item is an information-only display.
