Abstract: The call controlling or managing server (A) comprises a telephone platform database (B) containing detailed data (C) on calls, data (D) on data traffic associated to calls and data (E) referred to users and to their associated IP devices, with respective information including IP address, telephone number, etc. The system comprises a graphic user interface (GUI) which presents: a first interface (J) for configuring the corporate sites, a second interface (K) for configuring numbering plans and a third interface (L) for configuring voice and data billing plans. A module (M) for classifying calls divides calls into typologies according to the entered numbering plans. An additional value module (N) is used to determine call value, i.e. for calculating respective costs of both voice calls and data calls given the entered billing plans. Finally, reference O indicates one or more modules for creating generic and/or detailed reports which can be accessed by the system administrator.

Abstract: A label-switching and control interface for asynchronous fast-packet switching consisting of a set of label-switching and cell-processing units controlled by a suitable control unit. The units operate at each multiplex level in real time thanks to a microprogrammed logic requiring the control processor intervention only at the connection set-up/release. The units implement the low levels of the flow control algorithms necessary to conveniently exploit the advantages of the techniques. The label becomes indicative of a virtual circuit which is allotted only locally to the call, annulling thus the necessity of very extensive labels, while the parameters which characterize the connection which uses a particular label are stored in the unit itself.

Abstract: An interface interposed between a PCM data terminal and a processor comprises a bus accessor dialoguing with the processor, input and output circuitry coupled to the terminal, and intervening logic circuits and data stores designed to supply the processor in a time-division mode with preprocessed messages received or to be transmitted over a multiplicity of channels. The interface is operable according to dialogue procedures of HDLC type such as those corresponding to CCITT recommendations X25, X75 and N. 7, with switchover from one protocol to another.
