Reduced data flow in switched mode (SCPC)
In the event the data flow is reduced, for example a streaming file transfer termi-
nates, the SCPC switched demodulator detects the reduced flow and notifies the
VMS. Then, after a period of time determined by policies set for the network,
the VMS will send a switch command to reduce the size of the carrier band-
width.
This entire process is automatic following the policies established for the
network. The network is dynamically modified changing configuration to auto-
matically respond to changes to the network’s load.
The home threshold is the bit rate set to trigger a return to the home threshold.
This function is used when bandwidth has been allocated to meet load require-
ments, and the load has been either removed or partially removed. Since the
new load does not require the bit rate established, the Home Threshold is used
to determine when the bit rate falls below the preset threshold and switches the
channel back to its home condition, STDMA for example.
