Node Name
Enter a name (sixteen characters or less) for the node which helps identify the
Vipersat unit on the network.
Multicast Management Address
The Multicast Management Address is the multicast IP address assigned to all
modem units in the Vipersat network that are managed by the VMS. This
address must match the VMS Transmit Multicast Address.
When the modem unit receives a multicast from the VMS server, it receives
maintenance and control packets, including the server’s IP address. The unit
responds to the VMS server with a unicast containing its current configuration
data, including the unit’s IP address.. When the VMS receives the unicast
response, it registers the unit on the network.
STDMA
Clicking the STDMA menu item will display the Selective TDMA dialog
shown in figure 2-21.
The fields available for edit on this dialog will vary, depending on the function/
role that this modem unit is performing in the network.
For example, the CDM-570/570L shown in figure 2-21 is operating as a Hub.
All of the fields except for Enable Power Hunt appear. In contrast, the screen
shown in figure 2-22 shows a CDM-570/570L configured as a Remote, with
only a subset of fields available for edit.
If the unit is configured as an Expansion Unit — for either a Hub or a Remote
— the only STDMA option available is the Power Hunt setting.
Enable STDMA
Selecting the Enable STDMA check box enables Selective TDMA on this unit.
This option must be selected for a Remote that is to be included in the STDMA
Burst Map, for example.
Enable Power Hunt
The STDMA Power Hunt feature is active for Remote modems only, as shown
in figure 2-22. Should link reception from a Remote be incorrect or impaired
(e.g., poor environmental conditions), the STDMA Power Hunt feature is an
option on the Remote modem that automatically adjusts the Remote transmit
