Downstream Channel (carries data from the headend to the set-top)

Carrier

YES — The cable modem is locked to a DOCSIS downstream

Lock

channel.

 

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.

Frequency

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, or DOCSIS is not enabled, N/A is

 

displayed.

LKC

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.

Mode

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.

Power

The downstream channel power level in dBmV. If the value is

Level

invalid or cannot be retrieved, Carrier Lock is NO; 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; if DOCSIS is not enabled, 00.0 is displayed.
