4. EoC applications
EOC 1-32 and EOC 2-32 communicate with each other in the return path range of 5...204 MHz. All components
in the distribution structure must therefore be suitable for the return path. This applies in particular to the
antenna wall outlets, the passive distribution material and to SAT multiswitches.
4.1. Internet from cable network operator
If you use Internet access from a cable network operator, you will need a DOCSIS-enabled cable modem or
router.
Depending on the cable network operator, the forward path frequency range (downstream) amounts from
258 MHz to 862, 1006, 1218 or 1800 MHz. All components in the distribution structure must allow the
occupied frequencies to pass. For this reason, a prior test of the coaxial cable network should be carried out.
No signals (radio/DAB etc.) may be transmitted up to 258 MHz. Otherwise, frequency overlaps and interference
will occur.
4.1.1. The principle
TV and radio from the cable network operator are forwarded via the TV output of the BSD 963-00N and via the
EOC x-32 to the distribution network.
The IP data from the cable network operator is received at the modem port of the BSD 963-00N using a
DOCSIS router and forwarded via Ethernet to an EOC x-32. The EOC modulates the IP data and feeds it into the
distribution network via the G.hn output using its internal diplexer. The data can be received at the other EoC
devices.
Important: The use of a TZU 19-68X return path blocker is mandatory in order to achieve sufficient
blocking depth for the frequency range from 5...204 MHz. Otherwise it may cause interferences in
the cable network.
