About the KX-TDA systems

The Panasonic KX-TDA phone systems replaced the KX-TD systems, and are designed to provide features based on Internet Protocol and Local Area Networks, as well the conventional telecom network.

New features include VOIP (Voice Over Internet Protocol), LAN Networking, Advanced Remote Maintenance, SD memory card, CTI (Computer Telephony Integration), and digital wireless phones.

The KX-TDA100 and 200 control units ("KSUs") are constructed as card cages, like previous KX-T123211D, KX-T336, KX-TD500. Circuit modules slide into card slots to make contact with backplane. Cabinets can be mounted on a wall or rack, or placed on a shelf or the floor. Cabinets can be stacked.

These systems can use an optional internal IP Gateway Card for VOIP communications. By using the optional VOIP connection you can connect to a Local Area Network (LAN) or a Wide Area Network (WAN) to lower the cost of phone calls and unite distant offices or workers.
