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 |
| 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. |
