    摘要: A concentration method and concentrator arrangement enable a plurality of synchronous or asynchronous data terminals to be served by a common B channel of an ISDN to which the data terminals are connected by a digital subscriber termination and terminal adapters for transmission in packet mode. The terminal adapters are connected to the digital subscriber termination at the S0 basic access level. In the event of a request for B channel communication between a first data terminal served by a first terminal adapter and a packet mode ISDN port to which a second data terminal already has access via a second terminal adapter and via a first B channel, a transit connection is established between the two terminal adapters via the digital subscriber termination using a second B channel. Data packets conveyed between the first data terminal and the ISDN port are conveyed via the terminal adapter of the second data terminal.

    摘要: A facsimile apparatus processes a predetermined signal from a second external apparatus by means of correlating a first external apparatus with the second external apparatus if the facsimile apparatus is communicating with the first external apparatus when the second external apparatus transmits the predetermined signal to the facsimile apparatus. The signal is used for the operative connection between the facsimile apparatus and the second external apparatus. According to the present invention, the second external apparatus is prevented from frequently transmitting the predetermined signal to the facsimile apparatus. The present invention is applicable to a facsimile apparatus used for an integrated digital network.

    摘要: A method and apparatus for speaker recognition in a telephone switching system. For speaker recognition in, in particular, a system fashioned as an ISDN communications system, speech specimens are input into a telephone terminal equipment (T1, T2) and are pre-processed there, being, in particular, sampled with a sampling rate that is doubled in comparison to the usual sampling rate. The samples are transmitted to a switching system (VA) in the two ISDN data channels (B1, B2) in alternation, the actual speaker recognition (SPR) being carried out in this switching system (VA).

    摘要: Data communication is started when a first B channel is established between a source terminal and a destination terminal. Immediately before or after the start of a data transmission phase, the destination terminal is called a second time so that a second B channel may be established. Immediately before or after the data transmission phase, the use of one of the B channels is terminated. Accordingly, time required for data communication can be reduced.

    摘要: An integrated services communication system ISDN in which a plurality of ISDN supported terminal stations can be coupled to an S.sub.0 bus coupled to a private branch exchange, of which a maximum of 2 terminal stations can be active over B-channels. Them is proposed also to connect incompletely ISDN supported terminal stations to the S.sub.0 bus, which stations have many non-ISDN supported features, there being investigated on line cards which type of terminal station is connected. On the basis of a Terminal Endpoint Identifier (TEI) in a layer-2 message, either a standard ISDN protocol is handled from layer-2 onwards, or a firm-owned protocol.
