The invention relates to a method, arrangement and positioning board in a rack (R1) of a cross connect node in a telecommunication network. The arrangement comprises at least two interface units (L1, L2, L3, L4), each interface unit (L1, L2, L3, L4) comprising at least one motherboard (M1, M2, M3, M4) into which there is fitted at least first connectors (L1x, L2x, L3x, L4x) arranged so as to electrically connect at least one cross connecting card (XC1, XC2, XC3, XC4) to said motherboard (M1, M2, M3, M4), which said cross connecting card (XC1, XC2, XC3, XC4) is arranged for making network cross connections, and at least second connectors (L1c, L2c, L3c, L4c) arranged so as to electrically connect at least one interface card (L1i, L2i, L3i, L4i) to said motherboard (M1, M2, M3, M4), which said interface card (L1i, L2i, L3i, L4i) is arranged for making a network connection. Said motherboards (M1, M2, M3, M4) are fitted in the arrangement in such a manner that said at least one cross connecting card (XC1, XC2, XC3, XC4) extends so as to be simultaneously connectable direct to the first connectors (L1x, L2x, L3x, L4x) of each of said motherboards.
