ABSTRACT:
Switching apparatus with ISDN access that provides an ISDN interface unit which has the advantage of being realized in a separate housing with which already existing apparatuses realized on a module can be used, the switching apparatus being constructed via coupling with an ISDN module which handles the communication between ISDN and USB, wherein the apparatus can be connected to the personal computer while the latter is in operation, and constitutes a unit that can be sold and maintained separately.
