The design of the KX-TDA100 and KX-TDA200 allows your business 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 KX-TDA expansion cards operate on both the KX-TDA100 and KX-TDA200 systems. That means that if you outgrow the KX-TD100 system, you can unplug the expansion cards and plug them directly into the KX-TDA200 without having to buy a whole new system. In terms of maximum system capabilities the KX-TDA100 can offer up to 96 ports and the KX-TDA200 can offer up to 192 ports with 128 wireless phones (KX-TD7690, KX-TD7680)
All of the Panasonic KX-7000, 7200, 7300, 7400, 7600 and 7700 series proprietary phones work with the KX-TDA100 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. And, while you are upgrading, don't forget that the KX-TDA100 and KX-TDA200 can also be easily upgraded to the Panasonic multi-cell wireless telephones so it's easy to keep on top of things in a busy working environment.
Additionally, the KX-TDA100 and KX-TDA200 IP PBX systems have a small, compact design. But this does not diminish their capabilities.
