Specs
Pass Bit Rate(Mbps),190,300,Yes
It must have the following filename:
MoCAThresholds.dat
Note the following:
• You should never change a threshold name (first field), otherwise the threshold will become
unrecognizable and the unit will use a default instead.
• If any value exceeds a theoretical limitation, the unit will reset it to a valid value. For example, if a
percentage value exceeds 100, it will be reset to 100 upon import.
• You can precede any line with an exclamation point (!) to restrict the setting from editing onboard the
unit, for example:
!Pass CP Len(slots),30,35,Yes
In this case, the 30-35 range will be viewable on the unit, but will not be editable. Note that this
condition cannot be undone except by importing another thresholds file to the unit.
7.7 MoCA overview
The following sections provide an overview of MoCA, with a focus on details applicable to testing with the
MoCA module.
7.7.1 About MoCA
MoCA (Multimedia over Coax Alliance) is an “open, standard body promoting networking of multiple
streams of high definition video and entertainment using existing coaxial cable already in the home.”

MoCA has been formed because of the following two conditions that have recently converged:
• The increasing need for packetized, IP-based protocols to deliver multimedia services, such as IPTV
and video on demand (VOD), and
• The historical lack of an appropriate physical medium to reliably transport high-bandwidth packetized
data within the home
For high-bandwidth packet transport, the ideal physical transport medium would be a network of fiber
and/or Cat-5 copper cabling. However, most homes do not have this infrastructure and the installation of
it can be costly and inconvenient. But most homes do have an existing coaxial cable network due to the
prevalence of cable TV and outdoor antennas, so MoCA is intended to allow service providers to deliver
next-generation, packet-based services over the existing coaxial cable found in the home. While other
media typically exist such as phone lines, electrical wires, and wireless broadcast, coaxial cable is often
favored for the following reasons:
