Description
The DOCSIS downstream channel modulation: QAM 64 or QAM 256. If the
value is invalid or cannot be retrieved, Carrier Lock is NO, or if DOCSIS is
not enabled, 000 is displayed.
The downstream channel power level in dBmV. If the value is invalid or
cannot be retrieved, Carrier Lock is NO, or if DOCSIS is not enabled, 000 is
displayed.
The estimated downstream channel carrier signal-to-noise ratio in the format
xx.x dB. It is the value reported as SNR in the MIB. If the value is invalid or
cannot be retrieved, Carrier Lock is NO, or if DOCSIS is not enabled, 00.0 is
displayed.
The center frequency of the channel to which the DOCSIS upstream
channel receiver is tuned. It can be 5 to 42 MHz. If the value is invalid or
cannot be retrieved, Carrier Lock is NO, or if DOCSIS is not enabled, N/A is
displayed.
The DOCSIS upstream channel modulation: QPSK, QAM 8, QAM 16,
QAM 32, QAM 64, or QAM 128. If the value is invalid or cannot be
retrieved, or if DOCSIS is not enabled, N/A is displayed.
The upstream channel identifier 0 to 255. If the value is invalid or cannot be
retrieved or DOCSIS is not enabled, N/A is displayed.
The upstream channel power level in dBmV. If the value is invalid or cannot
be retrieved, or if DOCSIS is not enabled, 000 is displayed.
The upstream channel symbol rate in mega-symbols per second. If the value
is invalid or cannot be retrieved, or if DOCSIS is not enabled, 0.000 is
displayed.
Displays up to 32 MAC addresses learned by the DCX3200 cable modem,
including the Set-Top MAC and future MAC addresses assigned by DSG, in
hexadecimal format xx:xx:xx:xx:xx:xx on two screens if necessary. If the
value is invalid or cannot be retrieved, or if DOCSIS is not enabled, no values
are displayed.
