LANCOM 821 ADSL/ISDN – LANCOM 1621 ADSL/ISDN – LANCOM 1711 VPN

Chapter 1: Introduction

An 'Annex A' type LANCOM can only be used with ADSL-over-POTS service. Similarly, an 'Annex B' device can only be used with ADSL-over-ISDN service. Retrofitting a device to function with a different telephone system is not pos- sible.

ADSL-over-ISDN connections also exist that do not operate in conjunction with ISDN, but which use a conventional analog telephone connection. A prominent example would be Deutsche Telekom’s T-DSL service.

AVPN (Virtual Private Network) can be used to set up cost-effective, public IP networks, for example via the ultimate network: the Internet.

The models LANCOM 1621 ADSL/ISDN and LANCOM 1711 VPN are equipped with 5 channels by default. The additional LANCOM VPN Option can extend VPN support to 25 active tunnels. The VPN-25 Option also activates the VPN hardware accelerator in the LANCOM 1711 VPN.

While this may sound unspectacular at first, in practice it has profound effects. To illustrate this, let's first look at a typical corporate network without VPN technology. In the second step, we will see how this network can be optimized by the deployment of VPN.
