Method for separating narrowband and broadband services on a transmission link and a splitter element

Abstract

The invention relates to the separation of narrowband and broadband services in a telecommunications network. Signals belonging to a narrowband service are transferred in a first frequency range below a given threshold frequency and signals belonging to a broadband service are transferred in a second frequency range above said threshold frequency in the transmission link. The transmission link utilizes a splitter element comprising a low-pass filter unit and a high-pass filter unit, signals relating to narrowband service being separated to their dedicated interface by the low-pass filter unit and signals relating to broadband service being separated to their dedicated interface by the high-pass filter unit. In order that high-quality service may be offered to subscribers by means of a splitter element as simple and cost-effective as possible, filtering is implemented in the low-pass filter unit by means of a bidirectional active filter (LPF′).
