description A network element of a cable television (CATV) network, comprising an input for signal transmission; at least two diplex filters configured to be connected to said input, a first diplex filter comprising bandpass filters for a first upstream and downstream frequency bands and a second diplex filter comprising bandpass filters for a second upstream and downstream frequency bands, wherein an upper frequency edge of the second upstream frequency band is higher than an upper frequency edge of the first upstream frequency band and higher than or equal to a lower frequency edge of the first downstream frequency band and a lower frequency edge of the second downstream frequency band is higher than the upper frequency edge of the second upstream frequency band; a control circuit for measuring energy of radio frequency signals below said second downstream frequency band; and a switch for connecting one of said at least two diplex filters to said input, wherein said control circuit is configured to control the switch to connect the first diplex filter to said input in response to the energy of radio frequency signals below said second downstream frequency band exceeding a threshold value; or connect the second diplex filter to said input in response to the energy of radio frequency signals below said second downstream frequency band at most reaching the threshold value.
