Abstract
An arrangement for establishing a packet switched and a circuit switched connection between a first telecommunications system (NSS) and a second telecommunications system (WAN) comprises: 1) a packet switched converter (PSDC) for establishing a packet switched connection towards the first telecommunications system (NSS) and 2) a circuit switched converter (CSDC) for establishing a circuit switched connection towards the first telecommunications system (NSS). According to the invention, the arrangement also comprises a common data communications controller (CDCC) for establishing a connection between said converters (PSDC, CSDC) and said second telecommunications system (WAN). The interface of the common controller (CDCC) towards the second telecommunications system (WAN) is independent of its interface towards the first telecommunications system (NSS). For eliminating overlapping functions it is advantageous for the common controller (CDCC) to be adapted to perform as many as possible of the functions performed by the arrangement.
