offers concurrent support for Standard and High Definition Digital Broadcast Television, Switched
Digital Video (SDV), Video on Demand (VoD), and DOCSIS/Modular CMTS services.
The Cisco RFGW-10 UEQAM is a chassis-based product that is based on open standards with superior
performance, capacity, power consumption, ease of management and scalability. All components of the
Cisco RFGW-10 UEQAM are designed for high availability including dual Supervisor and Ethernet
switching line cards, N:1 Universal Edge QAM line cards, dual Timing and Control line cards, dual load
balancing and load sharing Direct Current Power Entry Modules (DC PEMs) and integrated RF
switching modules.
The Cisco RFGW-10 is part of the Cisco Cable ecosystem, and is fully integrated and tested as part of
the Cisco Digital Broadband Delivery System (DBDS) video solution and Cisco uBR10012 DOCSIS 3.0
and Modular CMTS solution.
The Cisco RFGW-10 is a centralized switching architecture leveraged from the Cisco Catalyst 4500
Series switches. The Cisco RFGW-10 is a 13 rack unit carrier class, modular chassis designed for
providing front-to-back airflow and system level redundancy. All chassis components are hot-swappable
and redundant. The chassis supports “wire-once” cabling for RF line cards and an integrated dual-zone
RF switch matrix. The supervisor engine provides non-blocking, Layer 2 to Layer 4 switching with the
addition of wire-speed 10-Gigabit Ethernet uplinks, 136-Gbps capacity, and 102-mpps packet
throughput.
The Cisco RFGW-10 system is a UEQAM that supports both upstream and downstream RF cards over a
frequency range of 5 MHz to 1.2 GHz. The initial line card release is a UEQAM downstream card that
supports the DOCSIS (1.0/2.0/3.0), the EURODOCIS, and J-DOCSIS specifications.
Based on the Cisco IOS networking software, the Cisco RFGW-10 supports advanced switching and
routing features.

Cisco RFGW-10 Functional Overview
The Cisco RFGW-10 is a Carrier Class Universal Edge QAM (UEQAM) platform that offers concurrent
support for Standard and High Definition Digital Broadcast Television, Switched Digital Video (SDV),
Video on Demand (VoD), and DOCSIS/Modular CMTS services. The Cisco RFGW-10 is an edge
modulation device that aggregates multiple High Speed Data and/or Video sources, processes and
modulates the digital MPEG content, and forwards the QAM modulated MPEG data to the subscriber
side devices (cable modems and set-top boxes).
1-2
The initial application of the Cisco RFGW-10 is primarily as a downstream data delivery system
(downstream from the Cisco RFGW-10 to the cable modem or set-top box). External data and
management sources (VoD servers, MCMTS devices, DNCS, and so on) aggregate into the system via
the Gigabit Ethernet and 10 Gigabit Ethernet interfaces on the Supervisor and the RF line cards. The
Cisco RF Gateway 10 Hardware Installation Guide
OL-16264-04
Chapter 1 Overview
Cisco RFGW-10 Functional Overview
Cisco RFGW-10 architecture is based on a centralized Layer 2 to Layer 4 Ethernet switch fabric. All
external Ethernet interfaces, whether on the line cards or on the Supervisor front panel, terminate at the
Supervisor engine’s switch fabric. Traffic on any of the external interfaces can be routed to any card in
the chassis.
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
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.
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 terminate at the Supervisor.
The Cisco RFGW-10 supports redundant, DTI source device inputs as part of the system clocking
architecture. It includes redundant DTI/TCC cards, which support DTI client functionality.
All line cards and modules are redundant. The Supervisors (RPR, SS), TCC, and DC PEMs support 1:1
redundancy. The line card slots can be enabled in either a single N+1 redundancy configuration or a dual
redundancy configuration (N+1, M+1). RF data path redundancy is enabled by the integrated RF Switch
matrix, which supports dual redundancy groups.
The following sections provide a high-level overview of the downstream data path:
1. Data packets are received by the Cisco RFGW-10 UEQAM via either the 10GE or multiple 1GE
interfaces.
2. Data packets are received by the switch fabric on the Supervisor card (all external Ethernet ports
terminate at the Supervisor Switch fabric). The supervisor forwards data traffic to the line cards
based on the session information and IP address. For data traffic, the supervisor de-encapsulates
IP/LT2P DEPI traffic and for Video, the supervisor de-encapsulates based on the IP address/UDP
range information.
3. All data path traffic terminates at the specific RF line card (chassis slots 3:12). All cards in the
system are synchronous to the DTI system clock reference.
4. For DEPI traffic, the DS line card extracts L2TP header information, parses and processes DOCSIS
packets, re-stamps data with DOCSIS time stamps, and completes the J.83 FEC processing.
5. For Video traffic, the DS line card classifies the video packets, manages intra-QAM scheduling,
PCR re-stamping, PID re-mapping, and J.83/FEC encoding.
6. The J.83 FEC encoded data is forwarded to the upconverter module, which modulates, upconverts,
and forwards data downstream in MPEG-2/MPEG-4 encoding.

Cisco RFGW-10 IOS Software
The Cisco RFGW-10 UEQAM runs the Cisco IOS software, which is stored on the compact flash
memory disks that fit in the single compact flash memory slot on the front of the Supervisor Cards. The
compact flash can store a Cisco IOS image or the configuration file.
In addition to the flash memory disks, each Supervisor module contains onboard flash memory that
stores a boot loader. The loader executes following a system reset to reload and execute the Cisco IOS
software on the flash memory disks.
The Supervisor module also stores the system configuration in the onboard flash memory. The
configuration information read from the flash memory is buffered in the operational memory following
initialization, and is written to the flash memory device when the configuration is saved.
Each line card also contains an onboard flash memory that is used to store a boot loader, similar in
function to that used on the Supervisor card. However, the line card loader executes following a system
reset, line card reset, or line card insertion to reload and executes any code that must run on the line card.
Software images may also be stored on an external TFTP server. Based on the configuration, the proper
image might be downloaded from the TFTP server and executed.

The Cisco RFGW-10 UEQAM is installed in a standard 19-inch equipment or telco rack. A rack-mount
kit ships from the Cisco factory with each router. The rack-mount kit includes the hardware needed to
mount the router in a standard 19-inch equipment rack or telco-type rack. Mounting in 23-inch
equipment rack is possible with optional third-party mounting hardware.
The components in the front include the Supervisor Cards, RF line cards, and the front panel LCD. The
components on the rear include the Fan Assembly, RF Switch cards (coaxial terminations), TCC (DTI
Clock) cards, and the power supply modules.
All components (excluding the LCD) are hot-swappable and field replaceable. A fully configured system
will operate with a single DC PEM installed; the second PEM is required for power supply redundancy
and power load sharing.
Note Proper configuration of the DC power input requires that both Input 1 and Input 2 are connected to the
external power source and the GND connections are connected to the Earth GND. Input 1 and Input 2
on the DC PEMs are not redundant power inputs. If only one of the inputs is connected to the external
power, the Cisco RFGW-10 UEQAM will not power-on correctly.

Fan Assembly
The Cisco RFGW-10 UEQAM system uses a modular fan assembly to dissipate heat from the system
and control the temperature of the chassis system components (except the DC PEM, which contains its
own internal fan). The fan assembly is a multi-fan design that pulls ambient air from the lower front of
the chassis and exhausts air out of the rear top of the chassis. The fan assembly provides individual fan
control and failure monitoring, multiple thermistors to monitor exhaust air and a wide range of speed
control parameters based on the system and the environmental conditions. Inlet air monitoring is
communicated to the fan tray via the system software from the sensors on each of the RF line cards.
The fan tray module provides the following features:

• Online insertion and removal OIR support
• Failure monitoring of individual fans
• Backup temperature monitoring to control individual fan rotation per minute (RPM)
• Usage counter based on hours of operation (CLI-based)
• Front panel LED for alarm status indication
• Control and power circuit failure alarms
• On board multi-level fan speed control based on system temperature
The fan assembly draws air into the chassis and directs it across the internal system components. The
heated air exhausts out of the rear of the chassis as shown in Figure 1-4.
Figure 1-4 Cisco RFGW-10 Airflow
Chapter 1 Overview
The fan tray has four speed levels based on the operating control modes for the system. After power on,
the fan speed is set according to the Supervisor provided ambient average air temperature and the
configured speed control mode in the system configuration. The default control mode setting configures
the fans at maximum speed. The speed of the fans regulate to a slower speed when the fan controller
stabilizes to the ambient temperature and chassis temperature. After startup, it may take up to 30 seconds
for the fans to stabilize at the requested RPM.
Figure 1-5 and Figure 1-6 show the fan assembly module. The fan tray has a single LED indicator (FAN
OK) located in the center of the module. The FAN OK LED status indicators are defined in Ta ble 1 - 2:

DC PEMs
Note Each DC PEM has an earth ground connection and two DC power input connections (Input 1 and Input
Chapter 1 Overview
The Cisco RFGW-10 system is powered by redundant DC PEMs. An individual PEM is capable of
providing 4536 watts of total output. The redundant modules work as a 1:1 redundancy configuration
and support OIR (hot swapping). These modules do not support current sharing as they are non-isolated
PEMs, which are diode OR'd into two separate load zones.
Each PEM includes two 60A input lines that operate between –40VDC and –60VDC input voltages.
Proper configuration and operation requires that both DC inputs are properly wired. The PEM also
includes an earth ground connection (this is not power return) for grounding the chassis.
2). Both external DC inputs (Input 1 and Input 2) must be connected as shown in Figure 1-7. Input 1 and
Input 2 are individual power inputs. Both power inputs on the PEM must be wired to external power for
the Cisco RFGW-10 UEQAM to operate properly. If both inputs are not connected to external power, the
Cisco RFGW-10 UEQAM will not power on.
DC PEM features:
• Closed frame, NEBS-compliant module design
• Front-to-back airflow (exhaust air exits out of the rear of the chassis)
• Power input range: –48VDC to –60VDC
• 4536W power capacity
• Supports OIR (hot swap)
• Supports 1:1 redundancy (system can run with a single PEM)
• CLI interface support for status and configuration
• Remote shutdown feature
• Front panel LED status and alarm indicators
Note When both the DC PEMs are installed, both need to operate with the breaker switches and the OUTPUT
OK LED on. If one PEM is not operational, it is recommended that the PEM either be removed from the
system or the power input cables be removed to limit the power supply Conductive Emissions (FCC
conductive Emission Requirements).
