Cisco RF Gateway 10 Supervisor Engine 7-E
Product Overview
The Cisco
®
RF Gateway 10 Supervisor Engine 7-E (Figure 1) for the Cisco RF Gateway 10 universal edge
quadrature amplitude modulation (U-EQAM) modulator redefines the way aggregation and traffic management
features are managed at the edge of the cable network. Specially optimized for the Cisco RF Gateway 10 platform,
the supervisor engine can be deployed in a redundant configuration with automatic failover. It runs the
comprehensive feature set available in Cisco IOS
®
XE Software Release 3.2.0 SQ, with an array of management,
line-rate Ethernet aggregation and switching, and packet filtering functions-all embedded in the carrier-class Cisco
RF Gateway 10 platform. The Cisco RF Gateway 10 Supervisor Engine 7-E provides the increased switching and
processing performance required for the new high-density Cisco RF Gateway Downstream 384 (RFGW-DS384)
Universal Edge QAM Line Card.

Before, switches and routers had to be externally connected to edge QAM modulators and configured separately to
manage them. As separate elements, switches and routers and edge QAM modulators provided limited
management functionality, and the result has been less-scalable edge solutions. Now, with the integrated Cisco RF
Gateway 10 Supervisor Engine 7-E, the intelligence of the Cisco IP Next-Generation Network (IP NGN) is available
for more efficient and scalable packet forwarding and management of line cards in the gateway.
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 DOCSIS
®
are
managed by the control plane (for example, setup and teardown of video sessions, creation of voice-over-IP [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.
