Industry Overview

Telecommunications

While many believe this industry to have been born out of the divestiture of AT&T in 1984, it can actually be traced to the Carterfone decision of 1968. Basically, a Carterfone was a device that allowed communication between a telephone and a mobile radio system base station. The Federal Communications Commission ruled that the Carterfone and other devices may be connected directly to the AT&T system as long as no damage was caused by these devices. This is the ruling that allowed customer provided equipment (CPE) to be connected to the Public Switched Telephone Network (PSTN).

Com-Bell’s Services

Cabling

Com-Bell Systems primarily installs information transport cabling systems. These cables allow signals to travel to and from Telephones, Computers, Fax Machines, Printers, Wireless Access Points, IP Based Surveillance Cameras to name a few.

Industry Accepted Standards recommend a minimum of two cables to the work area outlet (WAO or Jack). While the cables can be any combination of unshielded, shielded or fiber optic, they are usually unshielded twisted pair, Category 5e or Category 6 rated. All cables are installed from a central room on the same floor or area of the floor and terminated on patch panels or, if desired, wall field termination blocks in the Telecommunications Room (TR) or IDF. This cabling is also referred to the “Horizontal Cabling”. While a WAO should be planned for every 100 square feet of typical office space, the quantity may vary depending on the industry of the customer.

On larger projects where there is more than one TR or building, “Backbone Cabling” would also be required. This type of cabling may consist of multi-pair copper cabling for traditional telephony requirements, fiber optic cabling for data, video and security applications and/or coaxial cabling for CATV and data purposes. Backbone Cabling should be installed with future capacity kept in mind, as it may be very difficult and costly to install later.

With either types of cabling it is very important that the environment the cable is to be installed in is considered in the selection. For example, cable designed for outside plant environments are usually not listed for use indoors and must be transitioned to an indoor rated cable within 50’ feet of the point of entry.

The space cabling is installed is referred to as a “Pathway”. This can be as basic as “J” Hooks installed above a drop ceiling or it can be an elaborate system of wire cable tray and conduit stub-ups
