FOCX32
The data signal is bidirectionally transmitted via the cable TV distribution network. The coaxial
cabling setup (e.g. in tree or star structure) is uncritical. All ELCONnect coax modems
have equal access rights to the medium. The transmission uses a multiplexing procedure, allowing
for an automatical data rate adaptation, subject to the connection quality. This both
robust and effective transmission method offers a reliable data transfer even under the most
difficult circumstances. When several units are used, the data rate is dynamically shared.
Device set-up is effected by means of a configuration file, which allows the user to define all
the parameters needed for transmission, such as bandwidth allocation to the Clients, Quality-
Of-Service parameters, access permissions or transmission levels. If required, certain frequencies
can be spared out for transmission – a feature that may be necessary in hotel networks to
prevent interference with the transmission of Pay-TV signals. Apart from this, it is also possible
to reduce the signal level over an entire frequency range.
The optical Master represents the interface between the unidirectional cable TV distribution
networks and the bidirectional telecommunications network. For example, the FOCX32 can
be linked to a router, thus feeding the data signal at the outlet of the headend or the network
node into the coaxial cable network. The signal is then distributed to all TV outlets installed
within a radius of max. 750 m (depending on the environment). Through the TV splitter (included
in delivery) the signals from the Clients are supplied to the TV socket in the client´s
flat. This can be easily done without requiring further costs, since all the needed components
are included in delivery. The client is connected with the network interface card of the PC via
a patch cable. So he can use the "Internet access" without any further configuration of the
personal computers to be linked.
The ELCONnect coax modems are responsible for processing and modulation of the data
transmitted through the coaxial cable network, as well as for the provision of all interfaces for
optical fiber and coaxial link.
Thanks to their functionality, the modems, after being connected to a server or router
(FOCX32) or, respectively, to the network interface card of the relevant PC or router (Client),
are used both as transmitter and receiver of the information to be exchanged. Hereby the EL-
CONnect coax system functions as bridge between server or router, on the one side, and the
terminal equipment, such as PC or set-top boxes, on the other. IP addresses, for example, are
dynamically (DHCP) or statically allocated by the server or router to the linked terminals
(PC) the same way as it is normally done within a standard PC network.
So the modems are able to provide via the cable television network different services like an
Internet access. To ensure the integrity within a complex network, the Clients cannot communicate
among themselves, but only with the related optical Master.
