    Cisco IOS Release 12.2(50)SQ1 introduces the Cisco RFGW-DS48-1G line card. The Cisco RFGW-DS48-1G line card has similar features as the RFGW-DS48 line card, however it supports full DOCSIS DRFI compliance up to an operating frequency of 1GHz. The operating bandwidth of the Cisco RFGW-DS48-1G line card is 88 MHz to 1GHz.

  • Page 8 – Cisco RFGW-10 DS-48 Universal EQAM Line Card The Cisco RFGW-10 DS-48 line card is a 12-port, 48-channel UEQAM card designed to support Downstream External PHY Interface DOCSIS MPEG Transport (DEPI D-MPT), downstream data traffic, and video applications (VoD, SDV, and broadcast video). The RFGW-10 DS-48 card is similar to...
  • Page 9 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).
  • Page 10 The chassis must include all 12 RF Switch cards for proper operation. Note Each RF Switch card supports a single Cisco UCH2 connector header; the UCH2 supports 10 MCX coaxial connections per card. The RF Switch card is physically separate from the RF line card slots allowing insertion or removal of the RF line cards without disruption of the cable plant wiring.
  • Page 11 • RFGW-10-PWR-DC1 (DC PEM) The Cisco RFGW-10 system is powered by redundant DC PEMs. An individual PEM is capable of providing 4536 watts of total output. Redundant modules work as a 1:1 redundancy configuration supporting current sharing and online insertion and removal (OIR) (hot swapping).
  • Page 12 New and Changed Information RFGW-10 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.
  • Page 13 DEPI Path Redundancy (DPR) is used in conjunction with N+1 DEPI control plane redundancy for Cisco uBR-MC3GX60V line card. This feature allows you to configure a backup DEPI session on the protect card using the protect-tunnel command in DEPI tunnel configuration mode. In this mode, the protect line card has a fully operational secondary DEPI control connection and sessions for the QAM channels on the working line card.
  • Page 14 SDV sessions (for example, 10,000), the traffic outage time is around ten seconds. This is because, in Cisco IOS Release 12.2(50)SQ1, the underlying multicast function is not SSO-aware although the video session state is synchronized to the standby Supervisor card. The SSO performance of multicast video sessions will be improved in a later release.
  • Page 15 Video guides. New Software Features in Cisco IOS Release 12.2(50)SQ This section describes the new and modified software features supported in Cisco IOS Release 12.2(50)SQ. Supervisor Stateful Switchover In the Supervisor Stateful Switchover (SSO) mode, the standby Supervisor card is fully initialized and configured.
  • Page 16 The line card redundancy (LCRED) feature introduced in Cisco IOS Release 12.2(44)SQ supports DEPI D-MPT traffic under the DEPI Manual mode. In Cisco IOS Release 12.2(55)SQ, line card redundancy supports Video and DEPI D-MPT with DEPI Control Plane in the DEPI Protocol mode. In case of line card failure, OIR, or a forced line card switchover, the standby line card becomes active and continues to process Video or DEPI traffic.
  • Page 17 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. Release Notes for Cisco RF Gateway 10 in Cisco IOS Release 12.2SQ OL-18677-10...

    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.

GUI Monitoring GUI Monitoring is a web-based tool that enables operators to monitor the RFGW-10 system. GUI Monitoring is comprised of two functional components: a web browser client on a computer and a Web server residing in the Cisco RFGW-10 Supervisor card.
