DI-304/DI-304M ISDN 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.
Ordering Your ISDN Line
If you do not have an ISDN line installed already, we suggest that you order it from
your telephone company as soon as possible to avoid the long waiting period
common when ordering a new line. Use the information in this section to place the
order. If you have already installed your ISDN line, you can check the following
section to make sure that you can use all the features of your DI-304/DI-304M.
1. Contact your local telephone company’s ISDN Ordering Center.
2. Make sure DSS1 switches are available since these are the only switch types
currently supported by the DI-304/DI-304M.
3. When the telephone company installs your ISDN line, be sure to obtain the
following information:
◊ ISDN switch type.
◊ ISDN telephone number(s).
