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

MoCA Physical Layer Operating Characteristics
 MoCA Co-exists with CATV and DOCSIS
 Coexistence with other services is required
Cable modem upstream 5-42 MHz
Cable operator downstream 55-850 MHz with
expansion up to 1 GHz
 OFDM with Reed Solomon Forward Error Correction
 7 Frequency Plans
A1 800 – 950 Mhz
B1 850 – 950 MHz
C1 800 – 1050 Mhz
C2 850 – 1075 Mhz
C3 850 – 1100 Mhz
C4 875 – 1125 Mhz

 Standard Install and Service Practices remain
in place when MoCA enabled Whole Home
DVRs are deployed

Connectors
Cabling
Loss Calculations
Signal Level Requirements
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

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.

Considerations

22
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

been assigned.
 Verify that the TX Pkts and
Rx Pkts are incrementing
(screen refreshes every 5
seconds)
