• CF – This Remote has not sent an acknowledgement to the burst controller
since it was enabled.
Base
Entering a B at the command prompt in figure 3-20 allows entering the Remote
number to start displaying remotes in this menu screen. Entering the number 1,
as shown in figure 3-20, displays nine remotes, 1 through 9. If the number 4 had
been entered, the display would show the nine remotes starting with remote 4
(i.e., remotes 4 through 12).

Remote Count
The Remote Count menu item in figure 3-20 is an information only display
showing the total number of Remotes that currently belong to the STDMA
group for this Hub burst controller.
Set Remote Policies
This menu item, which appears for GIR and Entry Channel Hub types, allows
each Remote to be configured for specific data switching conditions.
For Hub STDMA Controllers operating in either GIR or Entry Channel mode,
typical load switching is not the mechanism that performs the transition from
STDMA to SCPC mode due to traffic load. In GIR mode, the Remote is
switched to SCPC as soon as the GIR threshold is reached. In Entry Channel
mode, the Remote is switched to SCPC as soon as the Hub receives the first
transmission from the Remote.
For both GIR and ECM, the event of switching from STDMA to SCPC can only
occur if the SCPC Switch Rate parameter is set to a value greater than 0 (zero).
If the switch rate for a Remote is set to 0 kbps, that Remote will remain in
STDMA mode and will only switch to SCPC mode due to an application switch
or a diagnostic (manual) switch.
Entering P at the STDMA Remotes Menu command prompt displays the
Remote Policies screen shown in either figure 3-23 (GIR Hub) or figure 3-25
(Entry Channel Hub).
