DI-304ISDN Remote Router
Installation & Setup

Before You Start

♦ Use only the power adapter supplied by D-Link Corporation (18 VAC 1A). Using an
incorrectly rated power adapter will result in damage to the router.
♦ Know the type of interface provided by your ISP or telecom. The standard model
only supports the ISDN BRI S/T-interface. If you are an ISDN U-interface user, you
need to order a U-interface model. If you are an ISDN S/T-interface user, you should
have an NT-1 or NT-1 plus provided by your ISP or telecom. Also, make sure the
ISDN line is available.
♦ In case of emergency, unplug the power adapter first.
♦ Locate the device in a clean location. Do not block the ventilating slots on the rear
panel.
♦ Cables must be attached to the correct ports; to do otherwise may result in damage to
the router. Keep cables away from walkways.
♦ If you use S/T-interface, do not extend the ISDN line greater than 100 meters from
the NT-1 (NT-1 plus) box and the router.
♦ If you use DSL/Cable, check that your subscribed DSL/Cable modem supports the
Ethernet interface for connecting to your PC. If not, you will be unable to connect it to
the router.
