The design of the KX-TDA100 and KX-TDA200 allows you to expand your system as your needs grow by plugging in   additional cards and telephones to the plug-in architecture.  All of the expansion card slots are universal, so that any card   can be plugged into any universal slot, allowing maximum use of what's available within the cabinet.  What's even   better is the TDA expansion cards operate on both the KX-TDA100 and KX-TDA200 systems.  That means if you  out grow the KX-TDA100 system, you can unplug the expansion cards from that system and plug them directly into the   KX-TDA200 without having to buy a whole new system.

   In terms of maximum system capacities the KX-TDA100 can offer up to 96 ports and the KX-TDA200 can offer up to   192 ports with 128 wireless telephones.

   All of the Panasonic KX-T7000, 7200, 7300, 7400, 7600, and 7700 proprietary telephones work with the KX-TD100   and KX-TDA200 systems, so if you already own a Panasonic system with one of these phone series it will be inexpensive   to upgrade to the KX-TDA system.

   Both the KX-TDA100 and the KX-TDA200 have Voice Over IP capability.  Telephone voice calls can be routed over   your local or wide area network that would otherwise just be used for data, thereby reducing traffic on the telephone lines   and reducing the overall cost when connecting systems and locations together.

 

 

  

    The KX-TDA50 is the little brother to the KX-TDA100 and KX-TD200.  It allows you to expand your system as your    needs grow by plugging in additional cards and telephones to the plug-in architecture.  This means, if you start with a    basic system and find that your needs have grown, you can add additional cards and telephones to your existing system    without having to by a whole new system.

 

    In terms of capacity, the KX-TDA50 can support up to 8 CO lines and 28 extension ports which, in turn, can support up

    to 28 wireless handsets and 24 wired telephones.  All of the KX-T series proprietary telephones work with the   KX-TDA50, so like the KX-TDA100 and KX-TDA200 upgrading your existing Panasonic system is inexpensive.

 

    The KX-TDA50 has a small, compact design, but that does not diminish its capabilities.  It has 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) at virtually no cost to the user.
