A landline telephone (also known as land line, land-line, main line, home phone, landline, fixed-line, and wireline) is a phone that uses a metal wire or optical fiber telephone line for transmission as distinguished from a mobile cellular line, which uses radio waves for transmission. The design process for a residential telephone system using structured wiring must address the inclusion and placement of the telecommunication wiring schemes, outlet boxes, wire termination, jacks, punch down blocks, patch panels, wire identification and labeling, and, of course, the telephone key sets (specialized phones designed to work with the key system unit). We will make sure your home telephone system wiring is properly installed and labelled. Below are some of the good brands of equipment we use for telephone equipment.
