Most people never see, or give thought to their voice and data cabling installation.
Perhaps you have seen some of the physical equipment or the jacks, but the cabling itself is usually hidden in walls or ceiling spaces. This cabling needs to be properly installed and terminated to avoid such problems as cross talk, electrical interference, and slow network speeds. Proper installation adhering to industry standards will also extend the life of the cabling. Although the majority of the cabling will be hidden away, there are some parts of the installation you can see. A messy installation of the equipment board usually means the same is true for the cabling.
