Upstream Modulation - Displays the modulation used on upstream ATDMA, TDMA,
•
SCDMA or MTDMA
Upstream Power Level - Transmit power level at which the cable modem is transmitting
•
on the respective channel
Downstream Bonding:
This section displays information about the RF downstream bonding with downstream channel
ID, Downstream Lock status, Downstream Bond Status, Downstream Channel Type,
Downstream Centre Freq., Downstream Band Width, Modulation, Power Level (Rx power level
at the gateway for the specific channel) and SNR Level.
Downstream Channel Id - The Cable Modem Termination System identification of the
•
downstream channel within this particular MAC interface. If the interface is down,
displays the most current value. If the downstream channel ID is unknown, 0 is
displayed.
Downstream Lock Status - Displays Locked if QAM and FEC are locked (indicates that
•
the channel is usable)
Downstream Bonding - Number of channels locked to downstream which can be used for
•
downstream data transfer
Downstream Channel Type - Displays if it is a SC-QAM channel or a OFDM channel
•
Downstream Centre Frequency - The center of the downstream frequency associated
•
with this channel
Downstream Band Width - The bandwidth of this downstream channel.
•
implementations are expected to support a channel width of 6 MHz (North America).
Downstream Channel Modulation - The modulation type associated with this downstream
•
channel. If the interface is down, it displays "unknown", else it will be either QAM64 or
QAM256 based on CMTS configuration
