KX-TDA50G - Big Bang for the Buck!

Competitive businesses need communication solutions that can change rapidly. The KX-TDA50G IP PBX helps keep your business on the cutting edge of telephony through the use of ongoing upgradability.

The KX-TDA50G is one model in Panasonic's mid-size IP PBX product line known as the "TDA Series." None of the cards in the TDA50G are interchangeable with any of the other TDA series PBXs. Features within the series are nearly identical with only the capacities being different.

The KX-TDA50G was introduced in the year 2000. Since then, it has undergone five (5) software revisions. The larger systems in the TDA series have been upgraded to the new KX-TDE series processor, which is our top-of-the-line, most feature-rich processor.

Panasonic KX-TDA50G offers state-of-the art wireless capability designed as part of the system instead of as add-on. The KX-TDA50G uses only one cabinet.

See Maximum System Capacity chart below for more detail.

Maximum System Capacity

Maximum Number of Trunks

See Note 1


Maximum Number of Wired Extensions

Not to Exceed Total

Maximum Number of Wireless Extensions

See Note 3

Note 1: The maximum of 20 Trunks is a combination of 12 Analog CO Trunks and 8 SIP Trunks. Even though the maximum number of trunks is 20 and the maximum number of extensions is 56, you cannot realize both at the same time since you would run out of slots.

Note 2: The maximum of 56 wired extensions is reached by using XDP and DXDP. The Memory Expansion Card is needed in order to go past 24 digital extensions. Your Panasonic Certified Dealer will help you balance these maximums so as to optimize the system for future growth.

Note 3: A maximum of 28 Wiresless Extensions may be programmed into the KX-TDA50 system, provided you use Panasonic Proprietary Cellular-like Telephones and Panasonic Proprietary Cell Stations.
