HAPTER 20: MANAGING CABLE MODEMS
Receive Power
(dBmV)
Receive power level from the CMTS for the upstream
interface from the cable modem. By default, the Receive
Power is set at 0, which is the optimal setting for the
upstream power level. Acceptable values are -160 to 260
TenthdBmV. The Receive Power is dependent on the
selected channel-width.
Timing Offset Measure of the current round-trip time for this cable
modem. Timing Offset is used for timing cable modem
upstream transmissions to ensure synchronized arrivals at
the CMTS. Units are in terms of (6.25 microseconds/64). A
value of zero is returned if the time is unknown.
Status Current cable modem connectivity state specified in the RF
Interface Specification. Returned status information is the
cable modem status as assumed by the CMTS.
Following describes the status value events that are
monitored:
