Abstract

Den foreliggende oppfinnelse vedrører en anordning for tilkobling til et offentlig telekommunikasjonsnett IVN og omfatter minst to sentral-enheter PINX, PINX2, CENTREX AXE til hvilke abonnentterminaler kan kobles, for eksem- pel en sentral-enhet, samt vedrører en framgangsmåte for innbyrdes kobling av to slike sentral-enheter. Hver sen- tral-enhet PINX, PINX2, CENTREX AXE omfatter et styreor- gan som er slik innrettet at det er i stand til å detek- tere en forespørsel som kommer fra en abonnent-terminal som er koblet til en første sentral-enhet PINX1, for til- kobling ti-1 en andre abonnentterminal som er tilkoblet en andre sentral-terminal PINX2, CENTREX AXE og ti oppset- ting ced hjelp av signalering og i avhengighet av nevnte detektering, en spesiell signaleringskanal via det of- fentlige telekommunikasjonsnett mellom den aktuelle sen- tral-enhet og den andre sentral-enhet dersom ingen slik signaleringskanal allerede eksisterer, samt å sette opp en talekanal mellom de to sentral-enheter.The present invention relates to a device for connecting to a public telecommunications network IVN and comprises at least two central units PINX, PINX2, CENTREX AXE to which subscriber terminals can be connected, for example a central unit, and relates to a method for interconnecting two such central units. Each central unit PINX, PINX2, CENTREX AXE comprises a control device which is so arranged as to be capable of detecting a request coming from a subscriber terminal connected to a first central unit PINX1 , for connecting ti-1 a second subscriber terminal which is connected to a second central terminal PINX2, CENTREX AXE and ten sets ced by means of signaling and depending on said detection, a special signaling channel via the public telecommunications network between the the relevant central unit and the other central unit if no such signaling channel already exists, and to set up a voice channel between the two central units.
