Signalling on low-voltage electrical installations in the frequency range 3 kHz to 148.5 kHz. Low voltage decoupling filters - Incoming filter1 Scope This standard applies to incoming filters used to control the coupling of signals between the utility area and the consumer area (see Figure 1). The standard defines the minimum impedance in the relevant frequency band(s) at both Utility port and Consumer port, the minimum attenuation of unwanted signals transmitted from the utility side to the consumer side and vice versa, the transmission characteristics: operating frequency domain for both
