7.1. World-Wide Mode
The SB6120E supports Motorola’s new “World-Wide” mode with dual certificate capability (BPI+),
allowing the modem to register on a EuroDOCSIS or DOCSIS CMTS. In addition, the SB6120E with
“World-Wide” mode enabled will scan for EuroDOCSIS-256QAM, EuroDOCSIS-64QAM, DOCSIS-
256QAM, and DOCSIS-64QAM signals.
• Enable World-Wide mode via TLV11 or SNMP using the following:
o cmFreqPlanType set to worldwideMode(3)
• Enable World-Wide mode via the SB6120E Internal Configuration HTML page using the
following:
o Access the SB6120E Internal Configuration HTML page via the local IP Address at
192.168.100.1
o Select the Configuration Tab
o Change Frequency Plan to Worldwide Mode via the pull-down menu
o Save Changes
7.2. SNMP CPE Access Control
The SB6120 supports (and requires) the following per the CM-SP-MULPIv3.0 specification:
• TLV55 SNMP CPE Access Control
If the value of this field is a 1, the CM MUST allow SNMP access from any CPE attached to it. If the
value of this field is a 0, the CM MUST NOT allow SNMP Access from any CPE attached to it.
Type Length Value
55 1 0 (Disable)
1 (Enable)
The CM MUST disable SNMP access from CPEs connected to the cable modem unless this TLV is
present in the config file with value equal to 1.
) Refer to SURFboard® Technical Bulletin 08-009 for SNMP CPE Access Control requirements
utilizing TLV55.
) Refer to SURFboard® Technical Bulletin 08-008 for SNMP NmAccess Control requirements.
7.3. Capture Bandwidth Selection
The SB6120 supports two downstream capture bandwidth options, 81MHz (Default) and 96MHz; where
the default value is 81MHz. Operators have the option of enabling the full 96MHz capture bandwidth by
setting the cmConfigTunerSpurAvoidanceMode MIB Object to the proper value.
)
Added the MIB Object cmConfigTunerSpurAvoidanceMode
• DESCRIPTION
Setting this object to mode81MHz(0) selects 81MHz spur avoidance algorithm for the tuner to attain
81MHz Capture Bandwidth.
(Default)
Setting this object to mode96MHz(1) selects 96MHz spur avoidance algorithm for the tuner to attain
96MHz Capture Bandwidth.
• Note(s)
A reboot is required for the changes to take effect. This includes modifications via SNMP or via
TLV-11 sets in the Cable Modem Configuration File.
This feature functionality needs support from CMTS.
7.4. SURFboard MIB Package
