The KX-TDA50
System
The KX-TDA50 was designed to provide growth for your business while maintaining a small, compact design. It also gives you the tools you need to provide small business solutions at an affordable price.
What that means to you is, if you find that your needs have grown, you can add additional cards and telephones to your existing system without having to buy a whole new one.

The design of the KX-TDA100 allows you to expand your system as needed by plugging in additional cards and telephones to this systems plug-in architecture.
One major benefit is the TDA expansion cards operate in both the KX-TDA100 and KX-TDA200 systems. In the event you outgrow the KX-TDA100 system, all expansion cards will operate in the KX-TDA200 cabinet.
