Specs
• Video QoS (Quality of Service) - Actively joins a multicast stream and measures the subjective
video quality. This test operates identically to the Video QoS test on other interfaces, such as the
10/100/1G interface. For more information, see Video QoS (Quality of Service) on page 6-23.
• Change Channel - Actively joins a multicast stream and measures the time required to switch to
another stream (that is, to “change the channel”). This test operates identically to the Channel
Change test on other interfaces, such as the 10/100/1G interface. For more information, see Change
Channel on page 6-51.
• Channel Guide Settings - Allows you to configure the use of a channel guide for IP video testing,
identical to other comparable functions on the unit. For more information, see Channel Guide
Settings on page 6-53.
7.4 Join MoCA Network In-Line (Bridging and passive testing)
(Select MoCA-RF > MoCA > Join MoCA Network In-line)
The MoCA module features dual MoCA interfaces which allow the unit to bridge traffic on a MoCA
network and perform passive monitoring, typically for video quality measurement. For example, the unit
could be placed in-line with an STB to monitor video traffic flowing across the bridge to the STB:

Once a bridge is established, the unit can also perform the full suite of active testing in either direction.
