4 DIAGNOSTICS

Field

Description

 

eCM Registered Displays whether the embedded cable modem has registered with the

 

cable modem termination system (CMTS):

 

• YES — DOCSIS registration is complete.

 

• NO — DOCSIS registration is in progress, or the set-top could not

 

register.

 

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

 

enabled.

 

 

Network

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

Access

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 The Days, Hours, Mins (minutes), and Seconds the DOCSIS system has

Timebeen 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-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.

MAC Addresses 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.

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.
