•
Current Slot – The time slot number that has been assigned to this unit in the transmission
cycle for switching from ECM to dSCPC.
•
Home State Revert Timer – The time, in seconds, that must pass without receiving
communications from the HCC (Hub Channel Controller – i.e., Demod #1 on the CDD-880,
the designated ECM controller) TAP message before this unit is reverted from dSCPC mode
back to ECM to re-establish communications settings for receiving the TAP. This parameter
is set in the VMS.
•
Probing Duration – Amount of time, in seconds, that this unit has been transmitting to the
