Connecting to ISDN in Europe
ISDN has been available for a number of years in Europe, but a standard has now been agreed
upon. It is known as Euro-ISDN. This version replaces the previous version of ISDN for each
country, and telephone companies and network providers are now upgrading their older ISDN
switches for the newer Euro-ISDN.
The NETGEAR Model RT210 router is approved to attach to both the French and German
Euro-ISDN networks. The French and German Euro-ISDN networks differ slightly from the
standard Euro-ISDN network approvals.
To connect to ISDN, you must request an ISDN line from the local telephone company and make
sure that Euro-ISDN is installed. If only the older version of ISDN is available, make sure it has
been upgraded to be Euro-ISDN compatible. The telephone company provides you with an ISDN
telephone number that you must use when installing the NETGEAR Model RT210 and Model
RT211 ISDN routers.
Line Ordering Summary for North American Users
When ordering your ISDN line, you should do the following:
1. Call your telephone company and ask what type of ISDN service is available in your
area.
The type of ISDN service is either National ISDN (available on AT&T, Northern Telecom, and
Siemens switches) or AT&T Custom.
2. Decide how many Directory Numbers and what other features you need, as described
above.
NETGEAR recommends that you order Caller ID if it is available in your area.
3. Provide the appropriate provisioning information to the telephone company.
4. Make a note of the switch type, directory numbers, and SPIDs provided to you by the
telephone company.
All of this information is required when configuring your router.
