The TDA 50 shelf is initially configured with 4
Hybrid Extension Ports and 4 Loop Start CO ports
(1 LCOT card), Power Supply, RS232 port, USB port, MOH port, Paging port and an SD card. The system is expandable to 12 COs and 28 extension ports. The 28 extension ports can support a combination 52 wired and wireless extensions.

All of the Panasonic KX-T7000, 7200, 7300, 7400, 7600, and 7700 proprietary telephones series work with the KX-TDA 50, KX-TDA100, KX-TDA 200 and KX-TDA 600 systems, so if you already own a Panasonic system with one of these phone series it will be inexpensive to migrate to the KX-TDA system, without changing out all the telephones. And, while you are upgrading, don't forget that these systems use the NEW multi-cell wireless telephones allowing more freedom to roam your office environment.

Additionally, the KX-TDA has a small, compact design like about the size of
a shoe box. But, that does not diminish its capabilities. A state-of-the-art engineering design has enabled the production of a small system that provides for a large amount of features while taking up less room.

The KX-TDA allows you to add a new level of security
to your business with the support of optional door intercoms and electrical contracts that permit you to control door intercoms and electrical contacts that permit you to control an electronic door strike or any other compatible electric device through the telephone. Each door intercom has its own distinctive ring and LCD display information so you can easily identify which door phone has been activated by a distinctive programmable ring.

Secure Digital (SD) Card

Reliability is key with any telephone system. The system software and local database information are stored permanently on the removable Panasonic secure digital
SD card. If for some reason the system suffers a catastrophic failure, you can be assured that all the important information on your system can be easily loaded back into the system from the SD card. In addition, the SD card makes it a simple task to upgrade the system with new features.
