The product is a WLAN router with integrated DSL modem, manufactured by Deutsche Telekom AG. It is a demonstration unit designed for use in private households or small offices where a stable internet connection via the DSL network is required. The device enables internet access via a wireless network in the 2.4-GHz frequency band with a maximum data transfer rate of 54 Mbit/s. The integrated NAT firewall provides basic protection for the local network, while the URL blocking function allows control over access to specific websites.

WLAN router with integrated DSL modem enables connection of a local network via the public DSL network. The device operates in the 2.4-GHz frequency band, which is a widely used standard frequency for wireless networks. The maximum data transfer rate of 54 Mbit/s corresponds to the IEEE 802.11g standard specification, designed to provide sufficient bandwidth for medium to high data rates in home environments. The router’s functionality includes data routing between the local network and the external internet, with the NAT firewall protecting IP addresses within the local network and enhancing connection security.

Functions and equipment in detail include the integrated NAT firewall, which is activated by default and monitors communication between the local network and the internet. The URL blocking function enables filtering of websites, preventing unwanted access to specific content. This feature is useful in environments where internet usage needs to be controlled, such as in family households or small workspaces. The device is designed as a demonstration unit, meaning it has already been put into operation but remains technically functional.

Technology explained simply shows that the router functions as a gateway, establishing the connection between the DSL line and the local network. The integrated NAT firewall translates IP addresses within the local network into a single public IP address to protect the identity of devices in the local network. The URL blocking function can be configured via a user interface to block specific websites. The WLAN function operates in the 2.4-GHz band, providing good range but being more susceptible to interference from other devices such as microwave ovens or other WLAN networks.

Compatibility and accessories refers to the use of the router with DSL connections available through the telecommunications infrastructure of Deutsche Telekom AG. The device is designed for use with standard DSL connections and does not require any special additional modules.

Installation and mounting typically involves connecting the router to the DSL socket and then connecting network devices via WLAN or Ethernet. Configuration is performed through a web interface accessible via a browser. Installation does not require special tools or technical knowledge of network protocols, as standard configuration occurs automatically. The device is designed as a demonstration unit, meaning it has already been set up but remains configurable for the end user.

The device is supplied as a demonstration unit with a 30-day warranty. The warranty covers technical defects that occur within this period.

Advantages in operation lie in the combination of DSL modem and WLAN router in a single device, simplifying installation and reducing space requirements. The NAT firewall provides basic protection for the local network, while the URL blocking function offers additional control options. The use of the 2.4-GHz band provides sufficient range for typical home and office environments. The device is suitable for use in private households and small offices where a simple and reliable internet connection is required.
