    • The invention relates to a cross-connection arrangement for a telephone exchange. The arrangement includes a frame (1), a number of frame-mounted subscriber-associated connection pins (24, 24') in one or more terminal units (2a), and a number of frame-mounted telephone-exchange-related line-circuit-associated connection pins in one or more terminal units (3a'). The terminal units are disposed close together and have necessary jumpers (23) for connecting selected subscriber connection pins with selected telephone-exchange connection pins via contact devices (33, 34) connected to the ends of said conductors. The contact devices (33, 34) and the conductors (31, 32) extend into an open space (26) defined by a bar (20) to which the subscriber terminal units (2a) are related.

    • The invention relates to a telephone exchange adapted line circuit connection that includes a predetermined number of line circuits (10a) each capable of being allocated to a telephone exchange subscriber, wherein the line circuits are coordinated on a printed circuit board (10'), wherein the circuit board has mounted thereon discrete components in the form of subscriber-conductor resistances (70) for each of the line circuits, and wherein the resistances are dimensioned for high heat dissipation. Each of the resistances (70) is comprised of a conductor, having an adapted resistivity and resistance, being mounted to a foil (71), and the foils are related to one or more heat-absorbing surfaces for effective heat transfer to the surfaces. Said conductors (70) in said foils (71) are connected to one or more contact devices (72) adapted for coaction with corresponding contact devices on the printed circuit board (73).
