Specs
• Replace the router with the unit - In this scenario, the router is disconnected and the unit is
connected to the coaxial network for synchronization. If both the provider WAN and residential LAN
coexist on the same cable, this type of configuration may be useful for logical testing directly towards
the WAN, perhaps to rule out the router as the cause for connectivity issues. Otherwise, it may be
useful for general bandwidth-related troubleshooting. Note that if you disconnect the router, the LAN
will be isolated from the provider network, and, if the router provides a DHCP service, no IP-based
activity will be possible unless addresses are statically assigned.
• Connect directly to the router - In this scenario, the unit and router form a small, isolated MoCA
network between themselves which allows the same statistics retrieval as any MoCA
synchronization. If bandwidth between the devices is poor or synchronization cannot be achieved at
all, a likely cause is defective MoCA hardware in the router or possibly the cable used for the
connection.
Figure 7-6 Emulating a router - Possible connection setups
Note the following:
• You must use the left port (port “A”) for all single-ended testing.
• When connected directly to another MoCA node with a short cable, an attenuator may be necessary
if the signal is too strong (or “hot”) for proper synchronization. Implementations may vary... please
contact Spirent for recommendations.
7.3.2 MoCA Network Statistics
MoCA Network Statistics provides access to a variety of statistics about the network with which the unit
is synchronized, including packet counts, bandwidth, and bit-loading profiles. When initiated, the results
are presented on several different pages:

Coax jack, connecting to
STBs, possibly the NT, etc.
