Method and arrangement for connection of a computer to a computer network via a telephone exchange

Telephone exchange for connection of a computer to a computer network via a telecommunication network the telephone exchange comprising:

• a switch core;
• a switch control means responsible for setting up connections between users of the exchange;
• at least one network connection device, in said telephone exchange, that is connected between the switch core and the computer network wherein the network connection device comprises a signal processing means that is arranged to receive data packets having a signal structure suitable for data communication from the computer network, to convert the signal structure of these data packets to a signal structure suitable for communication of data over a telecommunication network and to supply the converted signals to a computer via the switch core and the telecommunication network;
• and
• means for monitoring every connection set up between the computer and the computer network, wherein said means for monitoring is connected to the at least one network connection device.

Telephone system comprising an exchange and, a server for connection of a computer to a computer network via a telecommunication network, wherein the exchange comprises;

• a switch core;
• a switch control means responsible for setting up connections between users of the exchange;
• at least one network connection device, in said exchange, that is connected between the switch core and the computer network wherein the network connection device comprises a signal processing means that is arranged to convert the signal structure of data signals, received from a computer via the telecommunication network and the switch core, to data packets having a signal structure suitable for data communication and to supply these data packets to the computer network, and
• means for monitoring every connection set up between the computer and the computer network, wherein said means for monitoring are connected to the at least one network connection device, and the server together with the switch control means or the network connection device comprises means for access control for at least some of the connections set up.

Telephone system comprising an exchange and a server for connection of a computer to a computer network via a public switched telephone network, wherein the exchange comprises:

• a switch core;
• a switch control means responsible for setting up connections between users of the exchange;
• at least one network connection device, in said exchange, that is connected between the switch core and the computer network, wherein the network connection device comprises a signal processing means that is arranged to receive data packets having a signal structure suitable for data communication from the computer network, to convert the signal structure of these data packets to a signal structure suitable for communication of data over the public switched telephone network and to supply the converted signals to a computer via the switch core and the public switched telephone network, and
• means for monitoring every connection set up between the computer and the computer network, wherein said means for monitoring is connected to the at least one network connection device, and the server together with the switch control means or the network connection device comprises means for access control for at least some of the connections set up.

Method of connecting a computer to a computer network via a telephone exchange comprising the steps:

• receiving, in the telephone exchange, data signals sent from the computer, wherein the data signals are sent from the computer over a public switched telephone network;
• converting, by a signal processing means in a network connection device, the signal structure of the data signals to data packets having a signal structure suitable for data communication;
• supplying these data packets to the computer network;
• monitoring, by a local control means in the network connection device in the telephone exchange, every connection set up between a computer and the computer network.
