Telephone System Installation

What is involved in a typical phone system installation?

Typically most telephone systems interface an existing office wiring or building wiring through what is known as a telecom 66 block as shown in the schematic below. Most telephone systems use either a two wire or four wire configuration connecting the telephone system to the existing wiring. Incoming lines interface the telephone system using two pairs for each incoming line.

E System Sales, Inc. has available what we call an EZ install Cable & Block Kit that includes a telephone system wiring schematic making installation of a telephone system much easier for a typical do-it-yourself installer interested in saving money installing the telephone system.

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

PC Admin programming is also available for programming of most modern telephone systems using a Windows based Personal Computer. A Windows 2000 or XP PC Computer with an available USB or Ethernet port, PC Admin cable, and Windows computer skills are required to perform phone system programming.
