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.

Description

 

 

Mode

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.

 

 

Power Level

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.

 

 

SNR

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.
