Remove Retry Timeout
Entering T at the command prompt in figure 3-17 will display the Remove
Retry Timeout dialog shown in figure 3-30.
Figure 3-30 Remove Retry Timeout prompt
When a Remote is removed from the STDMA group, as described in the section
“Remove Timeout” above, entering a value in the Remove Retry Timeout
dialog defines the amount of time (in seconds) that is allowed to pass before a
retry attempt is made to return the removed Remote to the group. The Remote is
re-entered into the burst map cycle; if the Remote does not burst back (ACK) to
the Hub burst controller, it is again removed from the Burst Map.
This allows, again using a mobile remote as an example, shutting down the
remote at one location, moving it to a new location, and then automatically re-
establishing a connection to the satellite network.
STDMA Statistics
Entering V at the command prompt in the STDMA screen displays the STDMA
Statistics as shown in either figure 3-31 (Hub) or figure 3-32 (Remote). These
screens provide information for the number of Bursts (Remote only), number of
Burst Maps, and the current STDMA Cycle Length.
Because the Remote modem bursts back to the Hub once every cycle, the
number of Bursts displayed should be a multiple of the number of Burst Maps
displayed, with this multiple determined by the number of cycles per burst map
(1, 2, or more) that has been defined at the Hub. For the example shown in
figure 3-32 (Dynamic Cycle), the number of cycles per burst map is one, and
therefore the number of Bursts equals the number of Burst Maps.
