ABSTRACT:
System for coupling the public telephone network to the Internet in which a special number sequence is determined for the Internet Service Providers—ISP—and a specific number from the sequence is assigned to a specific ISP. For the Netherlands in particular a number sequence 067xxx can be used. From every telephone connection, a 067xxx-call can be led to an ISP across the shortest trajectory possible, which is to be judged by the network operator (NO). Per traffic exchange, one access to an ISP is established. All Internet traffic is led from the traffic exchange directly to the accompanying calling point of the ISP, in which the calling point can be coupled to an underlying number exchange as well.
