Conventional via ISDN

Without VPN, a LAN to LAN interconnection can alternatively be real- ized via ISDN. In this case, an intelligent line management and sophisticated filter mechanisms keeps connection costs low.

Remote access to the company network (via VPN or ISDN)

The work of many office workers in modern organizations is less and less dependent on any definite location—the most important factor here is unimpaired access to shared and freely available information.

Remote Access Service (RAS) is the magic word here. Employees working from home or field staff can dial into the company network via VPN or ISDN. When working with remote access via ISDN, the router protects the company network: the call back function only grants access to known and registered users.
