Description

Displays whether the cable modem has been granted access to the DOCSIS network:

•YES—The cable modem was granted DOCSIS network access

•NO—The set-top is obtaining DOCSIS network access

•N/A—The value is invalid or cannot be retrieved, or DOCSIS is not enabled

The Baseline Privacy Interface (BPI) status:

•YES—BPI has been successfully initialized for the cable modem

•NO—BPI initialization is in progress, has failed, or was not requested by the network

•N/A—The value is invalid or cannot be retrieved, or DOCSIS is not enabled

The Days, Hours, Mins (minutes), and Seconds the DOCSIS system has been operational. If the value is invalid or cannot be retrieved, or if DOCSIS is not enabled, each field displays zeros.

The Cable Modem and Set-TopIP addresses in dotted-decimal format xxx.xxx.xxx.xxx. Each byte value is padded with zeros when necessary. For example, 10.0.1.10 is displayed as 010.000.001.010. If the value is invalid or cannot be retrieved, or if DOCSIS is not enabled, 000.000.000.000 is displayed.

The Cable Modem and Set-TopMAC address in hexadecimal format xx:xx:xx:xx:xx:xx. Each byte value xx ranges from 00 to FF and is padded with zeros when necessary. For example,0:0:2D:1:F1:D is displayed as 00:00:2D:01:F1:0D. If the value is invalid or cannot be retrieved, or if DOCSIS is not enabled, 00:00:00:00:00:00 is displayed.

Carrier Lock

Frequency

Mode

Power Level

SNR

•YES—The cable modem is locked to a DOCSIS downstream 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

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 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, or 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, or 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, or 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, or if DOCSIS is not enabled, 00.0 is displayed.

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

Frequency

Mode

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.
