Description
• NO — The cable modem is not locked to a downstream channel.
• N/A — The value is invalid or cannot be retrieved, or DOCSIS is not enabled.
The center frequency of the channel to which the DOCSIS downstream channel
receiver is tuned. It can be 54 to 860 MHz. If the value is invalid or cannot be
retrieved, downstream Carrier Lock is No; if DOCSIS is not enabled, N/A is
displayed.
The last known carrier (LKC); the frequency of the last tuned downstream channel
used if the embedded cable modem enters hunt mode. It can be 54 to 860 MHz. If
the value is invalid or cannot be retrieved, Carrier Lock is No; if DOCSIS is not
enabled, N/A is displayed.
The DOCSIS downstream channel modulation: QAM 64 or QAM 256. If the value is
invalid or cannot be retrieved, Carrier Lock is No; 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; 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; 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; 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 if 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 DCX3510-M 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.
