premise equipment. At the time that the line is ordered, the customer may be asked for the FCC
registration number for the CyberSWITCH that is being used.
The cabling between the wall jack and the CyberSWITCH is very important, and is also where most
problems occur. The system’s PRI RJ-45 adapter uses the international standard of pins 3, 4, 5, and
6 for transmit and receive. Most T1 lines in the United States use the traditional 1, 2, 4, and 5 pins.
We provide an RJ-45 to RJ-45 Adapter that will convert between the two wiring systems.
When the line is installed, the customer 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?
5.
What is the
e for the line?
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.
