An Internet telephone adapter for setting up voice/data links, where a data conversion unit for data conversion between a subscriber terminal interface and a subscriber access adapter interface allows connection both to a packet-switching communications network and to a line-switching communications network.

Internet telephone adapter

In a wireless telecommunication system, for example a DECT/GAP system, under the control jurisdiction of a first telecommunication apparatus of the telecommunication system control mechanisms (i.e. messages, information elements and procedures) of a standard protocol (e.g. a protocol according to the DECT/GAP standard) are activated for the execution of a special protocol, which serve for the exchange of additional items of information between the first telecommunication apparatus and a second telecommunication apparatus of the telecommunication system.

Process and arrangement for executing protocols between telecommunications devices in wireless telecommunications systems

In a cordless telecommunications system with assured interoperability of cordless telecommunications applications, in particular a GAP-specific DECT system, having a cordless base station and having cordless mobile parts which are capable of telecommunication with the cordless base station via a radio interface wherein the number of mobile points exceeds the number of telecommunications channels which are available in parallel at the cordless base station, collective/group calls being possible while the interoperability of the cordless telecommunications applications remains ensured, mixed operation is implemented including a connection-based virtual-collective/group call and a connectionless collective/group call.
