    3. Multimedia over Coax Alliance- MoCA The Multimedia over Coax Alliance (MoCA) promotes and specifies delivery of digital entertainment and information content over the in-home coaxial cable Established in 2004 – Over 50 Members Leverage large installed base of Coax Large Worldwide deployment base of MoCA enabled devices There are three membership levels, Promoter, Contributor and Associate. Promoters are members of the board of directors. Promoter members meet formally once a month and are responsible for steering the overall direction of the alliance. there is also a Contributor class. At this level, companies participate in the development of the specification, have voting rights and are encouraged to participate in the various work groups and committees. Members are encouraged to upgrade from their current status, and companies new to the organization are welcome to join at this level as well. Associate level members have access to the specification for product development purposes, but have no voting rights and cannot participate in working groups other than the marketing work group.

    4. MoCA Technology Overview MoCA technology allows for the interaction of devices across the typical Coax in a home - similar to how IP data networks operate. Example - Whole Home DVR: Record programs on one device, and watch the program on another device in a different room. MoCA enabled devices co-exist with delivered services Video, High Speed Data, and Voice will co-exist with MoCA MoCA Version 1.0 and Version 1.1 are released Initial MoCA STB deployments are using MoCA v1.0 Support for up to 125 Mbps Application Throughput 270Mbps PHY rate Packet error rate better than 1 x 10-5. 95% of outlets achieve greater than 100Mb/s Supports 8 MoCA nodes on the MoCA network A Node in MoCA is similar to that in IP Networks Field tests of 250 homes indicate 110Mbps is available at 97% of outlets Familiar Medium – Cable companies know and understand Coax Coax is installed in most home and mostly by Televisions Low Sensitivity to Home Coax topologies MoCA throughputs are “net” throughputs Probing Mechanism allows Performance optimization per connection What is the status of the MoCA specification? The MoCA 1.0 MAC/PHY spec is ratified. Products with MoCA 1.0 embedded are available from several companies and include set top boxes, routers and gateways, bridges and ONTs. MoCA 1.1 extension has been ratified and offers additional benefits. These include parameterized quality of service (PQoS) for provisioning and bandwidth management of real time data requests for video applications. MoCA 1.1 with packet aggregation also increases the net throughput performance from 110 Mpbs to 175 Mpbs. MoCA is the only organization that actively promotes its net throughput metrics. While other may claim higher performance, these are generally theoretical bit rates. This is the difference between what is promised and what is received. This new extension also increases the network from the current eight nodes to 16 nodes. All these enhancements help network operators improve overall efficiency and manage total cost in their rollouts and service offerings. Products with MoCA 1.1 are expected sometime in the second half of 2010.

    5. MoCA Physical Layer Operating Characteristics MoCA actually supports 875-1525 Mhz ACMT uses BPSK to 256 QAM – 1 to 8 bits per symbol (sect. 4.3.8) 256 subcarriers There are two types of PHY packets – Data – which are MAC data frames or Probe packets – used to characterize communications channel There are 7 frequency plans- A Phy packet includes a preamble and a payload – the preamble is used to to provide a reference signal. ACMT – (p.110 MoCA 1.0) OFDM is a method for chopping a large frequency channel into a number of subchannels. The subchannels are then used in parallel for higher throughput.MoCA actually supports 875-1525 Mhz ACMT uses BPSK to 256 QAM – 1 to 8 bits per symbol (sect. 4.3.8) 256 subcarriers There are two types of PHY packets – Data – which are MAC data frames or Probe packets – used to characterize communications channel There are 7 frequency plans- A Phy packet includes a preamble and a payload – the preamble is used to to provide a reference signal.

    6. How do MoCA enabled devices work in the Home?

    7. MoCA Works over Coax and Splitters The physical layer can an will be random – the coax cabling topology in most homes does not conform to an standard MoCA uses Adaptive Constellation Multi-tone modulation which is based on orthogonal frequency division multiplexing Discuss Splitter Jumping MoCA operates outside of these limits but may have degraded performance.

    8. Physical Layer - Logical The Logical Layer is a full Point to Point Mesh Each Link may have a unique set of characteristics, the forward and reverse path may be different MoCA uses an optimized Phy parameter for each links called the phy profile The Phy layer uses Adaptive Constellation Multi-tone (ACMT) a variation of orthogonal frequency division multiplexing The nodes periodically send probes to determine link quality The modulation profile that is chosen ensures optimum link throughput and minimum packet error rates Dynamic Transmit Power Control is used to optimizes transmit power. When Broadcasting or Multicasting a Node must find a common set of Phy parameters – this is called a broadcast Bitloading Reed Solomon FEC is used on all data packets All PHY transmissions onto the medium use TDMA and are coordinated at the MAC layer by the NC The Logical Layer is a full Point to Point Mesh Each Link may have a unique set of characteristics, the forward and reverse path may be different MoCA uses an optimized Phy parameter for each links called the phy profile The Phy layer uses Adaptive Constellation Multi-tone (ACMT) a variation of orthogonal frequency division multiplexing The nodes periodically send probes to determine link quality The modulation profile that is chosen ensures optimum link throughput and minimum packet error rates Dynamic Transmit Power Control is used to optimizes transmit power.

    10. IP Technologies and Open Standards Talking Points JEFF PRESENTS THIS SLIDE JEFF - After you provide an overview of these 3 new IP technologies & the role of each, please transition to the next slide as follows: Now that we have covered these 3 new technologies, let’s dig a little deeper into how each function within the Cisco next generation set-top box portfolio. The MoCA equipped Explorer 8600 series is at the heart of Cisco HD whole home DVR and transmits content to other set-tops within the home. Explorer 4600 series, Explorer 1640HDC & Explorer 1540C devices can also be MoCA equipped and function as clients for DVR functionality on other TVs throughout the home. Our Cisco network processor combined with our DTCP-IP technology embedded on the silicon allows the Explorer 8600 to stream digitally encrypted an secure IP video throughout the home that is consistent with an HD broadcast quality experience. This is not an Internet video experience, but a true HD quality video experience. DLNA allows for expansion of services with other devices in the home network. Our next generation set-tops are DLNA 1.5 capable, meaning that our set-tops can communicate with other DLNA compliant consumer electronic devices available through retail.

    16. MoCA Installation Considerations

    17. Installation Considerations Standard Install and Service Practices remain in place when MoCA enabled Whole Home DVRs are deployed Tap to TV Loss Calculations Connectors Signal Level Requirements Cabling Splitters MoCA Point of Entry (POE) Filter recommended as close as possible to premise entrance location to avoid potential for Home to Home interference and to improve in-home receive levels

    18. Cisco MoCA Enabled Set-top Activation The STB’s should automatically form a MoCA network after two or more MoCA devices boot up. MoCA link indicator will illuminate after STB Boots on and the STB joins a MoCA Network. Each STB is referred to as a MoCA node. A given STB refers to itself as the local node.

    19. Point of Entry (POE) MoCA Filter Prevents interference between MoCA homes on the same tap or Point of Entry Minimizes MoCA energy on CATV feeder Generally located at Residence Point of Entry (gnd. block) or at the TAP Not recommended for self-install – installed by cable tech Key Operating Characteristics Passband 5 – 1002 MHz, Stopband -35 dB at 1125 – 1525 MHz CATV Feeder line is the coax line running down the street (could be on poles or buried underground) Can be located at the TAP or Point of Entry, sometimes called the ground block by cable techs The Passband allows the std cable signals to continue to operate as is today The Stop band stops any interference from getting into the 1125 – 1525 MHz bandwidth. It stops the interference in the MoCA Band. Basic Installation – Most installations will be at the TAP or the POE. This simply shows the filter at the POE. Installation with Cable Modem – By placing the Filter below the first splitter, you will have less db loss of the signal. You lose ~ 3.5 db of signal as it goes through each splitter loop. If you place the filter at the bottom as shown then there is ~ 7 db loss of signal but if you place it up above the 1st splitter then you would have ~ 14db loss. The signal would travel up to the 2nd splitter and back down again (thus more loss). These splitters might be in the garage, side of the house or attic so loosely speaking it is still close to the Point of Entry. Placing the filter at the TAP is less desireable than at the POE (gnd block) area. The filter is attenuating the MoCA signal that wants to go up to the first splitter… thus getting more signal from the MoCA Server (E8642 STB) to the Client (E4642 STB). Installation with TWC type C House Amp – This scenario is used where you are not getting enough signal level into your home. The Amp/Filter/Splitter many times will be in one box – TWC has specified this type of box. The Amplifier will booth the signal to an acceptable level. The Cable Modem can be representative of either a Cable Modem or many times now an EMTA (Embedded Multimedia Terminal Adapter) which does the job of providing High Speed Data and Telephony. But why is the filter not at the POE. Again, having it positioned lower will help the signal loss from Server(ex. Exlporer 8642HDC) to the Client (Explorer 4642HDC). Also it should be noted that having the House Amp below the splitter allows the EMTA to still function if there is a power outage (it has battery backup). 95% of the time, placing the filter a the TAP will probably be ok but homes with a lot of loss would do better having it at the POE or further down into their network. It’s ultimately up to the MSOs how they deal with the MoCA frequecy management and they will have their technicians install the MoCA filters, etc.. as it is a technical install in the attick, POE area or TAP area.CATV Feeder line is the coax line running down the street (could be on poles or buried underground) Can be located at the TAP or Point of Entry, sometimes called the ground block by cable techs The Passband allows the std cable signals to continue to operate as is today The Stop band stops any interference from getting into the 1125 – 1525 MHz bandwidth.

    20. Home Interference Example without MoCA Filter Background – this example shows what can happen on a MoCA network with out a MoCA filter installed. For this particular example let’s look at a couple of definitions: Homes 1 & 2 both have MoCA networks with a MoCA Server (ex. E8642 STBs) sending MoCA traffic to various Clients (ex. 4642 STBs) throughout the home. The Aggressor signal in Home 1 is the signal that is affecting the MoCA network in Home 2. The Agressor STB is sending out Interference into Home 2. Thus the name Victim for the Client STB in Home 2. MoCA interference sent from Home 1 into Home 2 mixes with the signal from the Server in Home 2 causing that path to fail and the end result is that the Client STB then receives a bad signal In this example, The Aggressor signal is the interference that mixes the Victim level causing the MoCA link to fail. The solution would be to install MoCA filters on both sides of the -20dB TAP so that the MoCA networks would not interfere with each other.Background – this example shows what can happen on a MoCA network with out a MoCA filter installed.

    22. MoCA Troubleshooting Considerations

    23. MoCA Troubleshooting Considerations Basic Troubleshooting of Whole Home DVR Nodes: Verify POE Installed correctly If used in your deployments. Verify Whole Home DVR can play recorded programs on the local unit and verify quality. Verify MoCA Node (STB in another room) can play recorded content and the video quality is the same as on Whole Home DVR. If Whole Home DVR and MoCA node do not play out recordings, a potential issue may exist in the network between the two devices. Leverage Whole Home DVR Diagnostics or Test Equipment to diagnose and isolate problems in the network.

    24. Preliminary Cisco Whole Home DVR MoCA Diagnostics Node Summary and Network Page Summary: Node and Network Information Status: Verify status is Link up, indicating that the node has successfully joined the network. Broadcast PHY rate: Wait at least 30 seconds after Link Up is achieved. Verify Broadcast PHY rate is at least 150 Mbps (this parameter will be available in a future software release).

    25. Preliminary Cisco Whole Home DVR MoCA Diagnostics Node Statistics Unicast PHY rates: Verify that Unicast PHY rates to other nodes are all at least 180 Mb/s. Broadcast PHY rates: The Broadcast PHY rate of each node is visible. Verify that Broadcast PHY rates are at least 150 Mb/s Local node RX level: Verify that receive levels from other nodes are all -54dBm or greater. Approx Path Loss: This parameter is not needed for performance verification, but is useful for compiling data on path loss in homes. As a general guideline, path loss should be 54 dB or less.

    26. Preliminary Cisco Whole Home DVR MoCA Diagnostics MoCA Interface Info Page Verify that the MoCA IF IP and MoCA IF mask have been assigned. Verify that the TX Pkts and Rx Pkts are incrementing (screen refreshes every 5 seconds)

    27. Options for handling Low Local node RX level

    28. With a MoCA enabled home, the potential is endless….
