Verifying that DOCSIS 1.0+ Devices Successfully Register

There are two ways to verify that DOCSIS 1.0+ devices successfully register and that
the BSR 2000 recognizes them.

Troubleshooting DOCSIS 1.0+ Interoperability

If a phone call cannot be established turn on the following EVT from Global
Configuration mode:
MOT(config)#logging evt set c 11:RESSF 1-10
Verify that there are no indications that the grant-interval and grant-size are not being
matched. If EVT "RESSF.1" is reported, verify that the running configuration file has
a QOS profile configured with the grant-interval and grant-size specified in this EVT.

Implementing Spectrum Management

The spectrum management system monitors the upstream signal integrity, and collects
upstream spectrum information. When signal integrity degrades due to noise, the
spectrum management system automatically configures the upstream channel
parameters to maintain low packet loss by changing the upstream frequency,
modulation profile, channel-width and/or power level to ensure that upstream
performance stays at acceptable levels.
The following tasks are used to implement frequency agility on the BSR:

Review the EVT messages displayed on the console. The following information
EVT should be displayed on the console if a cable modem has successfully
registered as DOCSIS 1.0+:
[05/14-15:28:58.09- 11:REG]-I- REG.15 DOCSIS 1.0+ enabled
for CM, for MAC add r: 0008.0e16.fafe
Use the show cable modem mac command from xxxx mode. The output of the
command indicates DOCSIS version for each cable modem. Output is similar to
below.
