The front panel display includes two Gigabit Ethernet ports and a single DVB-ASI interface (covers all
video output streams). The front panel connectors support both copper and fiber SFP modules. The front
panel Gigabit Ethernet ports are not processed directly by the line card; these are independent of the line
card and route directly to the Supervisor card switch fabric. These ports do not go out of service if the
line card crashes and a failover to the redundant card occurs.
A critical feature of the DS-48 line card is redundancy and high availability support. The line cards are
designed to detect and react to a wide range of faults and failures, and respond with sub-second failover
to a dedicated protect card. In the Cisco RFGW-10 platform, DS-48 line cards can be configured with
1:N redundancy (up to 1:9), resulting in a fully-protected, high capacity, and highly dense EQAM
solution.

Cisco RF Gateway 10 Supervisor Engine V-10GE
The Cisco RFGW-10 Supervisor Engine V-10GE provides data path and data control for all network
interfaces and provides 10-Gigabit Ethernet interfaces for uplink connections. The Cisco RFGW-10
Supervisor design is leveraged from the Cisco Catalyst 4500 Series switch Supervisor family.
The Supervisor Engine V-10GE has a very high performance Ethernet switching feature set. Advanced
traffic management features include:

The Cisco RFGW-10 Supervisor Engine V-10GE handles the management of DOCSIS and video traffic
for the RF Gateway 10 system. Management of data and video traffic can be split into data plane and
control plane processing. The data plane manages the aggregation and forwarding of multiple services
to the edge QAM resources (for example, Ethernet switching, routing, aggregation, and filtering).
Interactions with control interfaces for video and Data over Cable Service Interface Specifications
(DOCSIS) are managed by the control plane (for example, setup and tear-down of video sessions,
creation of VoIP calls, management of high-speed data services, and management of the distribution of
packets and environmental factors in the gateway). The aggregation management utility in the
Supervisor engine allows cable operators to extract detailed information from a single line card on the
overall operational status of the entire gateway.
The Supervisor engine receives either DEPI (DOCSIS) data or video data (MPEG/UDP/IP) and forwards
the data to the RF line cards based on either the DEPI session content (IP/L2TP) or encapsulated video
session information (IP/UDP). All data path traffic is terminated at the line cards. The Supervisor engine
receives data traffic, classifies the traffic, and forwards the data traffic to the line cards.
Control traffic for DOCSIS (DEPI mode), video, and HA functionality is terminated on the Supervisor
engine. Local video mode (CLI, GUI, SNMP), remote video mode control plane (DNCS, GQI), and
native video mode (GQI v2, object model) are implemented in the IOS and terminated at the Supervisor
engine.
