Field Description
Network
Access
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
Initialize BPI 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
System Up
Time
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.
IP Addresses
The Cable Modem and Set-Top IP 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.
MAC
Addresses
The Cable Modem and Set-Top MAC 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.
Downstream Channel (carries data from the headend to the set-top)
Carrier Lock
• 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
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 if 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, or 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, 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.
Upstream Channel (carries data from the set-top to the headend)
Frequency 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.
Mode 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.
