## Abstract

A network terminal and an Internet Protocol IP access node in an access network. The network terminal gives instant access to a multitude of communication services such as telephony, video, data, multi media as well as services provided by Internet. In the access network IP is used as an internal multiplexing and transport technique. The speed at which data is transported on the access line is limited by the used modem technique, not by the restrictions posed by the general public switched telephone network. Several terminals may be connected to one and the same access line.

## Claims

### Claim 1

An access network comprising a number of subscriber lines, at least one network terminal, a network node, a high speed modem provided at the subscriber line interface of each network terminal and a corresponding number of corresponding high speed modems provided at access line interfaces of the IP access server, wherein each network terminal has a subscriber line interface and at least one interface connecting a subscriber communication facility, and the network node has a telephony network interface, an IP access server, an IP router that is connected to the IP access server and that has an IP network interface, and a telephony server connected to the IP access server and to the telephony network interface, the at least one network terminal being connected to the IP access server at at least one access line interface provided in the IP access server, and each one of the high speed modems providing high bit rates from about 140 Kbps to about 20 Mbps and above using an xDSL protocol selected from the group comprising a DSL protocol, a HDSL protocol, a VDSL protocol, an ADSL protocol, an SDSL protocol.

### Claim 2 (depends on 1)

The access network of claim 1, wherein the IP access server comprises a high speed modem providing high bit rates from about 100 Kbps to about 20 Mbps and above.

### Claim 3 (depends on 1)

The access network of claim 1, further comprising an IP multiplexor having several inputs and one output, the network terminals being connected to the inputs over respective subscriber lines and the output being connected to the IP access server.

### Claim 4 (depends on 3)

The access network of claim 3, further comprising a high speed modem provided at the subscriber line interface of each network terminal and a corresponding number of corresponding high speed modems provided at the inputs of the IP multiplexor, each of the high speed modems providing high bit rates from about 140 Kbps to about 20 Mbps and above using an xDSL protocol selected from the group comprising a DSL protocol, a HDSL protocol, a VDSL protocol, an ADSL protocol, and any future high speed digital subscriber line protocol.
