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 servicesVideo, High Speed Data, and Voice will co-exist with MoCA
MoCA Version 1.0 and Version 1.1 are releasedInitial MoCA STB deployments are using MoCA v1.0
Support for up to 125 Mbps Application Throughput270Mbps 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

Installation Considerations Standard Install and Service Practices remain
in place when MoCA enabled Whole Home DVRs are deployed
Tap to TV Loss CalculationsConnectors Signal Level RequirementsCabling 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
© 2010 Cisco Systems, Inc. All rights reserved. 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.
© 2010 Cisco Systems, Inc. All rights reserved. 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

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.

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).
Diagnostic Screen is Preliminary and Subject to Change

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.
Diagnostic Screen is Preliminary and Subject to Change
