ARRANGEMENT FOR CONNECTING A TELECOMMUNICATIONS DEVICE TO A PACKET-SWITCHING COMMUNICATIONS NETWORK

摘要

The invention relates to an arrangement (10) for connecting a telecommunications terminal (20a, 66) or a private branch exchange (20b) to a packet-switching communications network (40, 58) and to an interface unit (22, 62, 70), a communications terminal (20a, 66) and a private branch exchange (20b) for connecting to a packet-switching communications network (40, 58). The arrangement has at least one telecommunications device (20a, 20b), such as a telephone (20a, 66) or a private branch exchange (20b), which can be connected to a circuit-switching communications network. The arrangement also comprises an interface unit (22, 62, 70) which is connected to the packet-switching communications network (40, 58) and to the telecommunications device (20a, 20b). The interface unit (22, 62, 70) converts at least part of the data (A to F) determined for the subscriber connection by means of the packet-switching communications network (40, 58) into data (A' to F') of a circuit-switching communications network (40, 58).
