Zusammenfassung:PCT No. PCT/IB96/00144 Sec. 371 Date Nov. 6, 1996 Sec. 102(e) Date Nov. 6, 1996 PCT Filed Feb. 26, 1996 PCT Pub. No. WO96/27998 PCT Pub. Date Sep. 12, 1996In a telecommunication system, more particularly for the range of ISDN technology, which includes a switching device (1), a telecommunication terminal unit (19) coupled to the switching device (1) via a first number of bus lines (3, 4, 5, 6), and (9, 10, 11, 12) for providing phantom power supply to the telecommunication terminal unit (19) via the first number of bus lines (3, 4, 5, 6), user communication means including actuation switches (28) and indicator lamps (29) are coupled to the telecommunication terminal unit (19) via a second number of bus lines (14, 115, 16, 17). This enables simplified telecommunication with minimum circuitry and cost. Power is supplied to the communication means (28, 29) by the telecommunication terminal via the second number of bus lines (14, 15, 16, 17).
