While the Internet connections can be either ADSL, Cable modem, or ISDN (for those models with build-in ISDN interface). For LAN-to-LAN connections through ISDN, a direct ISDN connection is build-up between two LANs. This type of connections are possible for Vigor2200X, 2200W, 2600X, 2600W, and other products with ISDN interfaces.
