Viewing the Cable Broadband Configuration Details
You can view the following Cable technology configurations:
DTI Client—The DOCSIS Timing Interface (DTI) client collects DTI server master clock, DOC SIS
timestamp, and Time of Day information from the DTI Server. It interfaces with the DTI Server to
provide Time, Frequency and Management interfaces to the Modular Cable M od em Termination
System (M-CMTS) device.
QAM Domain—Quadrature Amplitude Modulation (QAM) domain
MAC Domain—A MAC domain is a logical subcomponent of a Cisco CMTS router and is
responsible for implementing all DOCSIS functions on a set of downstream and upstream channels.
The CMTS MAC domain typically includes one or more downstream paths and o ne or m ore
upstream paths. Depending on the CMTS configuration, the CMTS MAC domain can be d efined to
have its downstream on one cable interface line card with its upstreams o n a no the r ca rd, o r one or
more CMTS MAC domains per cable interface line card.
Narrowband Channels—A Narrowband Channel is a logical representation of a non-bond ed channel
that is a standard DOCSIS 1.x/2.0 protocol downstream channel that contains one RF ch annel. The
wideband protocol utilizes the existing narrowband downstream channel for carrying the MAC
management and signaling messages and the associated narrowband upstream for return data traffic
and signaling.
