Enabling/Disabling Cmts Concatenation Capabilities; Enabling/Disabling Concatenation For Docsis 1.0 Or 1.1 Cable Modems - Motorola BSR 2000 Configuration And Management Manual

Release 1.0

Enabling/Disabling CMTS Concatenation Capabilities

CMTS concatenation allows an MSO to enable or disable CMTS concatenation
capabilities. Enabling the concatenation feature allows the CMTS to do concatenation
with participating cable modems. This increases per-CM upstream throughput by
combining multiple MAC frames into one packet request. Cable modems request only
one DOCSIS timeslot on the upstream channel for multiple small packets, as opposed
to having to request an individual timeslot for each MAC frame.
CMTS concatenation also allows an MSO to disable CMTS concatenation. Disabling
CMTS concatenation would be useful in preventing potential concatenation-related
problems from occurring.
Use the following CLI commands, in Cable Interface Configuration mode, to enable
or disable CMTS concatenation capabilities:
MOT (config-if)#cable upstream <NUM> concatenation
MOT (config-if)#no cable upstream <NUM> concatenation
where:
Enabling/Disabling Concatenation for DOCSIS 1.0 or 1.1 Cable
Modems
Concatenation can be enabled or disabled specifically for DOCSIS 1.0 or DOCSIS
1.1 cable modems.
Use the following CLI commands, in Cable Interface Configuration mode, to enable
or disable concatenation for DOCSIS 1.0 or DOCSIS 1.1 cable modems:
MOT (config-if)#cable cable concatenation { docsis-1.0 | docsis-1.1 }
MOT (config-if)#no cable cable concatenation { docsis-1.0 | docsis-1.1 }
where:
526360-001-00 Rev. B
NUM is the upstream port number.
docsis-1.0 enables/disables concatenation for DOCSIS 1.0 cable modems only.
