Smaller applications are those with typically fewer than 3,000 square feet. They generally have 1 or 2 analog phone lines and 8 phones or less. There are normally phones in the kitchen, family room, 3-4 bedrooms, laundry room and perhaps a garage phone. Small homes can usually get by with our entry-level, KX-TA824 analog system when the need is for basic features or the KX-TDA50 on the more feature-rich side. Often times, door phones are used in place of a door bell.
