Reference Guide for the Model RT210/RT211 ISDN Routers
Ordering ISDN Lines C-7
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.
Your ISDN circuit should conform to EURO-ISDN, NET3, or 1-CTR3 standards.
This information is required when configuring your router.
2. Know the ISDN numbers of your local and remote sites.
3. Order the CLI option from your local carrier if you require CLI for security.
4. Order both B channels to have the same ISDN number, if possible. This is sometimes
known as Auxiliary Working and can speed up connection times.
