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
