The invention relates to a method for tying additional function modules into a control facility of a switching system and to a switching system. A switching system comprises a control facility (CONTR) provided with a plurality of basic function modules (APP1 to APP3, BP1 to BP4) which are mutually coupled to each other, for controlling the switching functions of the switching system. The basic function modules (APP1 to APP3, BP1 to BP4) are coupled to one or more access modules (ACC). The additional function modules (APP11 to APP23, KONVERT1, KONVERT2) access the basic function modules (APP1 to APP3, BP1 to BP4) only via the access modules (ACC), such that at any given time each of the access modules (ACC), depending on the accessing additional function module (APP11 to APP23, KONVERT1 , KONVERT2), provides the additional function modules (APP11 to APP23, KONVERT1, KONVERT2) with only one individual logical access interface (INT1 to INT4) to the basic function modules (APP1 to APP3, BP1 to BP4).
