• ECMv2 – Slot Data Length
On a Hub unit, entering B and M at the command prompt brings up the dialogs
for specifying the data length in milliseconds for the target CDM-570/570L, as
shown in figure 3-18.

On Remote units, this menu item is an information-only display.
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.
