Release Notes for Cisco RF Gateway 10 in Cisco IOS Release 12.2SQ
New and Changed Information
The RFGW-10 performs line card switchover on such events as a user-initiated switchover command,
line card insertion and removal (OIR), as well as hardware and software faults, RF upconverter failure,
and DTI failure on the line card. At line card switchover, the standby line card becomes active, resuming
the functions of the line card it is switched from. With the internal RF Switch card, line card switchover
is transparent to the RF connections to the plant.

The line card redundancy supports M-CMTS D-MPT traffic. The line card switchover has little impact
on the DOCSIS applications. This release does not provide line card redundancy support for video
applications.

1:1 Supervisor Card Redundancy
The Cisco IOS Route Processor Redundancy (RPR) feature enables the RFGW-10 to use two Supervisor
cards in a redundant configuration, such that if the active Supervisor card fails or becomes inactive, the
system automatically performs a switchover, where the standby Supervisor card takes over and assumes
full responsibility for systems operations.
cards in a redundant configuration, such that if the active Supervisor card fails or becomes inactive, the
system automatically performs a switchover, where the standby Supervisor card takes over and assumes
full responsibility for systems operations.
The RPR mode is the simplest mode in which the standby Supervisor card completes its initialization
but suspends just before parsing the startup-config. The standby monitors the active Supervisor and
switches over when it detects a failure on the active Supervisor or when the user issues a switchover
command. When the standby Supervisor card becomes active, all the line cards in the chassis are reset
and the startup-config is parsed. There will be a traffic outage in this mode because the line cards are
reset.

1:1 Timing, Communication and Control (TCC) Card Redundancy
The Timing, Communication and Control (TCC) card operates in 1:1 redundancy configuration in the
RFGW-10 chassis, where each TCC card has its own peer as a dedicated backup card in case of failure
(hot standby mode). Only one of the two TCC cards provides the DTI client functionality at any given
time. The standby TCC is accessible from other line cards, but does not provide any DTI functionality.
In the event of active TCC failure, the standby TCC becomes active and serves as the DTI client.

Video
The Cisco RFGW-10 performs MPEG-2 video processing for Video on Demand (VoD) and Digital Video
Broadcast applications. The video feature involves both video control plane and video data plane
functions. The control plane resides on the Supervisor card and the data plane runs on the DS-48 line
card.

functions. The control plane resides on the Supervisor card and the data plane runs on the DS-48 line
card.
The video control plane provides video session configurations with table-based UDP port-to-QAM port
mapping. The table-based mapping is used only for unicast video sessions. Apart from the table-based
mapping, the Cisco RFGW-10 also supports the flexible port mapping method, where the users can set
up video sessions by configuring the mapping dynamically. The flexible port mapping can be used for
both unicast and multicast video sessions. In addition, the video control plane provides show commands
for users to access run-time session information.

The video data plane processes Unicast Constant Bit Rate (CBR) Single Program Transport Stream
(SPTS) for VoD sessions with Trick Mode support, which provides functionalities like fast forward,
rewind, and pause for an MPEG stream. It also serves Multicast Multiple Program Transport Stream
(MPTS) for DVB Pass-Through sessions.

The data plane supports the video feature with a number of video-processing functions including
Program ID (PID) remapping, Program Clock Reference (PCR) restamping, Dejittering and Clock
Recovery, and Program Specific Information (PSI) processing.
