31、Classification Segmentation filters are used to separate one powerline communication system that operates in one operating frequency band, in several independent segments. The combination of the appropriate segmentation filter in conjunction with an incoming filter and/or with an impedance filter sh
32、all be made according to local regulations. 3.1 Type 1: Asymmetrical filter This filter has one “supply backbone port“ and one “segment port“. The “supply backbone port“ and the “segment port“ have different impedance characteristics in the operating frequency band and shall not be inverted. Communi
33、cation may not be possible on the “supply backbone port”. 3.2 Type 2: Symmetrical filter This filter has two “segment port“. Both “segment ports“ have the same impedance characteristics at the operating frequency band and may be inverted. Usually the ports of a symmetrical segmentation filter are co
34、nnected to different segments of one mains communication system.

38、shall be in the frequency band 95 kHz to 148,5 kHz for consumer segmentation filters. The manufacturer shall specify the operating frequency range. 4.3.2 Impedance 4.3.2.1 Asymmetrical segmentation filter (type 1) On the segment port of the filter, when measured in the operating frequency range spec
