HAPTER 18: CONFIGURING AND MONITORING CABLE MODEM TERMINATION SYSTEMS
Overview
The Cuda 12000 performs DOCSIS 1.0 and 1.1 and EuroDOCSIS 1.0 CMTS
functionality to provide connectivity and data passing for cable modems over
the cable plant. This chapter describes the configuration and monitoring
capabilities of the Cuda 12000 DOCSIS and EuroDOCSIS modules.
Note: You must have access privileges to the HFC functional area to perform
CMTS configuration functions.bb
CMTS Upstream Frequency Reuse
The Cuda 12000 supports the configuration of upstream channels with the
same center frequencies, if the channels are on separate non-combined
physical plants. Referred to as upstream frequency reuse, this allows an
operator to set aside less of the valuable upstream spectrum for CMTS use.
Note, however, that for proper operation such upstream channels must also
be configured to have the same channel widths and minislot sizes.
Before You Begin
Before you configure the CMTS, navigate to Network Browser >
GroupName > ChassisName > Cuda Chassis Manager > Configuration >
CMTS > Interfaces.
The Interface window provides several configuration tabs and a module
information display. The module information panel, located in the top of the
window, identifies the interface and the module-type currently selected.
