Total Slot Count

This menu item appears for Hub units operating in ECMv2 only.
This parameter defines the number of time slots per cycle available for assign-
ment to the Remotes in queue that are to be switched from ECM into dSCPC.
These are the Remotes that are tagged for Online mode. By design, ECM works
on a contention basis, with the number of slots being some fraction of the total
number of Remotes. In order for this ratio to be optimized, a Vipersat calculator
is available to determine this setting.
Tip: Contact a Comtech Vipersat Networks representative for a copy of the
latest Vipersat ECM Calculator.
