1 Application
With these devices you can implement installations for up to 1000 participants, all are fed
from the same external unit. Fundamental explanations can be found in the installation
instructions for the GigaSystem 17/8G and K.
In all these accessories units the return channel signals are transmitted to the CMTS
(Cable Modem Termination System) in a linear frequency, passive, low-dam-ping
mode. In the process, the terrestrial system is operated as an active one.
In conjunction with suitable headend- and participant- technology, this enables the
provision of fast Internet access, VoIP, and voting options – all without the need for
additional cables to be installed.
Such applications are only cost-effective in large installations.
