USER'S GUIDE
For non-U.S. and European installations, a standard 4 or 8 wire cable with RJ-45 jacks is sufficient.
When the line is installed, you must ask the phone company the following questions:
1. What are the phone numbers for the line? (There may be more than one.)
2. Do I need to use any prefix when I dial? (For example, "9" for a Centrex line.)
3. What type of switch is the line connected to?
4. For # 4ESS, what release of software is running on the switch?
When the phone company installs the line, they assign it certain characteristics (sometimes called
translations). These are different depending on the type of ISDN switch to which the line is
attached. The customer must know what type of switch is being used.
The following table provides correct settings for important configuration options.
