Table 7-3 Node Stats
Statistic Description
Vendor/
MAC
MAC-layer address of the node’s MoCA interface and the vendor name associated with
it. The unit attempts to determine the vendor by using a MAC address lookup table in the
System menu area. If the vendor cannot be determined, it is reported as Unknown. For
more information, see Vendor MAC Address on page 7-27.
Node
Version
Highest level of MoCA supported by the node, but not necessarily the version in use by
the node. For more information, see About multiple MoCA versions on a single network
on page 7-38.
State State of the node, typically one of:
• MAP Active - The node is actively participating on the network in a normal manner.
• Idle - The node is recognized as a valid node but has entered a state of inactivity,
such as a “sleep” mode. All bandwidth to and from the node will be reported as zero.
Bit Rate The physical layer bit rates to and from the node (Tx and Rx) in Mbps, up to the
theoretical MoCA maximum of the respective standard (see MoCA overview on
page 7-31).
CP-LEN
(Cyclic Prefix
Length)
The size of the guard interval applied to MoCA symbols in each direction to protect the
symbols from interference. Larger lengths reduce bit rates and thus reduce the
bandwidth.
Phase
Offset
The phase difference between the MoCA channel’s reference center frequency and the
actual center frequency, in Hz. When phase offset increases, it diminishes the ability of a
MoCA receiver to properly demodulate the channel subcarriers. Large values, such as
47000 or higher, lower the margin for interoperability.
Log Gain
Mean
The average amount of gain required to amplify the MoCA carriers received by the unit.
A higher gain value corresponds with greater attenuation between the unit and the node
under test. The valid range is 0-68 dB. Because this parameter applies to the behavior of
the receiver, it always displays as N/A for the transmit direction.
Power
Adjust
The amount that the unit’s transmit power is reduced from reference power. A lower
value indicates that more power is required and therefore corresponds with greater
attenuation between the unit and the node under test. A larger number indicates more
power reduction, therefore the larger the number, the “cooler” the signal and vice-versa.
The range is 0-30 dB in multiples of 3 dB. Because this parameter applies to the
behavior of the transmitter, it always displays as N/A for the receive direction.
Preliminary issue - Limited distribution only!
