•
Traffic less than 2 Mbps - Multicast streams may have been blocked in the core
network. Check all devices with multicast traffic passing through them have the
IGMPv2 protocol enabled. Check an IGMP querier is set within the VLAN.
Trace loss multicast traffic back to Core switch for any misconfiguration.
•
Traffic greater than 30 Mbps - IGMP Snooping may not be operating correctly,
and multicast streams are flooding the network with traffic. The Ethernet port
of the Set-Back-Box is 100MbE and thus physically limited to 100Mbps. If traffic
on the L2 switch port connected to the Set-Back-Box exceeds this limit the Set-
Back-Box shall not operate correctly. Check all devices with multicast traffic
passing through them have the IGMPv2 protocol enabled to limit the traffic to
only the multicast TV station a box is tuned to.
6. Monitor network traffic to confirm there are IGMP join/leave multicast stream
requests from the Set-Back-Boxes to the IGMP Querier. A Set-Back-Box shall
always request to join the multicast stream associated with TV station entitlement
(239.0.0.1:10000 by default), with a bitrate typically no more 1Mbps. If the Set-
Back-Box is out of standby and displaying live TV, its shall also request the
video/audio multicast stream associated with the TV station (one between
239.0.0.2:10000 and 239.0.3.255:10000 by default) typically between 3 to 15Mbps
for a non-4K/UHD channel and 4 to 24Mbps for a 4K/UHD channel.
37. vuStreamer Cable Connections
1.
Satellite input
- A Multistacker is used to combine all LNB outputs into one
output. Check for the secure connection of:
•
The Multistacker output to a 2-way splitter input
•
The 2-way splitter output to a surge protector (provided with the
vuStreamer) and
•
The surge protector to the H,Lo input on the vuStreamer.
Important:
The spare output on the 2-way splitter provides a test port for signal
measurement plus attenuation from the Multistacker to reduce signal power to
the level required by vuStreamer.
2.
Terrestrial input
– Check for the secure connection of the FTA terrestrial
signal (if available) from the terrestrial source to a surge protector (provided
with the vuStreamer) and the surge protector directly the Ter input on the
vuStreamer.
3.
Ethernet outputs
– Check for secure connection of Ethernet 1 (Mgmt.) to the
property’s Core switch. Check for secure connection of Ethernet 2 (IPTV
Output) to the same switch.
4.
Earthing
– Check a minimum of 2.5mm

to ground the vuStreamer chassis to a known electrical earth point (CET).
