The NEC DSX Phone System

Do-it-yourself installation. The NEC EZ Installation cable connector kit makes installing the DS2000 a breeze. Click on the link on the right side of the page for an exploded view of the NEC EZ Installation cable connector kit. After you have followed the instructions on this page and in the NEC DSX installation manuals you have received with your phone system, your phone system will be ready to power up. All DS2000 systems with software version 03.00.00 are plug and play. You will be ready to send and receive phone calls.

NOTE: 1 pair of wires is required on all incoming phone lines and phone extensions. A 66 Block termination punch down tool is also required for installation.

Punch down the appropriate pair of wires for each terminal. For example, the 300R & 300T terminals are the terminals for the first phone extension which is extension 300, and the Line 1R and the Line 1T terminals are for the first incoming telco line witch is Line 1.

The above diagram is a schematic view of the telco 66 Block provided in the installation kit. Click here for a exploded view of a 66-Block. The installer will notice that there are 2 empty terminals on the bottom of the 66 Block. That is normal.

PC Admin programming is also available for programming the NEC DS1000/2000 phone system through a Windows based Personal Computer. A Windows 2000 or XP PC Computer with an available serial port, PC Admin cable, and Windows computer skills are required to perform phone system programming.
