To address this situation, RDK-B does not include DOCSIS. It only includes components that provide an abstraction layer software interface to third party WAN. For the DOCSIS WAN, this component is known as the Cable Modem (CM) Agent. CM Agent provides interfaces for integrating WAN interfaces with RDK-B. RDK-B is not tied to DOCSIS and may be used with any WAN interface. Other RDK-B software components can be created that provide interfaces to other WANs.

Architecture

• CM Agent is a CCSP component that exposes TR181 parameters related to CM/DOCSIS interface characteristics.
• CM agent provides info like: Upstream channels, downstream channels, boot file name, DOCSIS log etc along with CM interface details.
• Maintains a TR181 data model XML file with dbus object path as /com/cisco/spvtg/ccsp/cm
• Has a layered architecture similar to any other CCSP component
