Abstract: The invention relates to a connector module (100) which is used for telephone transmissions, more particularly adapted to transmissions on ADSL subscriber lines. The module (100) comprises a housing (108) including two parallel rows—(R1) and (R2)—of contacts facing each other, whereby each of said contacts comprises a first terminal part (106) for connection to a conductor and an opposite second terminal part (107), two successive contacts of a same row defining a pair of contacts, wherein each of said second terminal parts (107) normally rests elastically against the second terminal part (107) opposite. The module (100) also comprises a detachable card (104) for electrical connection and lowpass filtering of signals transmitted between the second terminal parts of at least one pair of contacts of a row, i.e. first pair, and said second terminal parts of at least one pair of contacts on the other row, i.e.
