CDM-840 Remote Router MN-CDM840
Ethernet-based Remote Product Management Revision 3
6–63
• Aloha State – The Aloha State indicates the current state of this unit during the ECM cycle:
Unit is not transmitting; either inactive or waiting for switching assignment.
Unit is actively transmitting (probing) to the Hub for either registration or request for switching
to dSCPC.
Remote has successfully switched from ECM to dSCPC.
• Current Tap – Indicates current value of sequential progression of TAP message
transmission. Ranges from 0 to 255, then repeats.
• 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
HCC to request registration and switchout.
• Seconds Until Next Probe – The time period, in seconds, before this unit will again transmit
to the HCC.
ECM Tx Statistics
This section provides the following read-only information:
This is the total number of transmissions since the modem entered Entry
Channel Mode.
This is the number of successful (entire) transmissions received by the hub.
This is the number of incomplete transmissions that were detected by the hub.
This is the number of transmissions that were undetected by the hub
This displays the status of the most recent transmission as Success, Failure, or
No Detect.
This is the number of seconds since the last transmission, regardless of status.
Whenever the modem reverts from dSCPC to ECM, the statistics will clear.
