POI
The EoC transmission is done in the return channel frequency range of
2…68 MHz, which is also used for Internet services in broadband networks.
For this reason, it must be ensured that the EoC signal does not cause distur-
bances in the cable network via the point of interconnection (POI)
– e.g. by
using a commercially available high-pass filter at the output of the CATV
amplifier.
