RCM Overview
The Router Control Module (RCM) provides the forwarding capability for the C4/C4c CMTS. Its centralized capabilities
include: layer 3 routing, layer 2 switching, tunneling support, DOCSIS 3 functionality, and the Network Side Interfaces
(NSIs). It is responsible for the control plane and for traffic management in the data plane. IPv4 and IPv6 are both
supported. A duplex C4 CMTS chassis employs dual RCMs for full Control Complex Redundancy (CCR). High-speed
backplane data links interconnect the RCMs with the client cards.
