The Panasonic KX-TDA - A complete communication solution for both small and medium-sized businesses.

System Overview

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 is 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 outgrow 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 series 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 200 can also be easily upgraded to our mulit-cell wireless telephones so it's easy to keep on top of things in a busy working environment.

Additionally, the KX-TDA has a small, compact design. 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.

One important thing to note about this system is that there is always a dial tone waiting for each phone that is connected to the system - even during the busiest times of the day. Where some systems only allow a certain number of calls to be made at any given time, these systems do not limit the number of calls.

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. The KX-TDA100 supports up to 9 (16 on the KX-TDA200) door phones and 8 contact closures (16 on the TDA200).

2.4GHz Multi-Cell Wireless Capability

KX-TDA Multi-Cell Wireless option allows voice and data transmission via radio waves, within the range of strategically placed cell stations (antennas). As you move throughout the coverage area, the system provides seamless communication by automatically handing off the call from cell station to cell station. There are two Multi-Cell wireless handsets: the KX-TD7680 and the premium KX-TD7690. Up to 128 handsets can be registered on either the KX-TDA100 or KX-TDA200 and handsets can also be registered on multiple systems. Multi-Cell Wireless is a low-cost and highly flexible solution that keeps people connected whether they are on the factory floor, in the warehouse, in a showroom or just about anywhere on site. 7690 phone


If you are designing your companyís private telephone network or simply connecting the PSTN, the KX-TDA has a wide variety of cost-effective options to choose from to meet your specific requirements:

  • T1 and ISDN Primary Rate Service
    The systemís T1 or ISDN Primary Rate service allows 2 pairs of wires to be electronically divided into 24 channels, which eliminates the need of running separate lines and provides an extremely cost-effective way to connect the system to the telephone companyís central office.

  • Q-SIG
    The Q-SIG protocol is the most flexible platform available for future development. Supported by international standards organizations (ITU-T and ETSI) it ensures that the KX-TDA will connect seamlessly with other vendorís systems and non-Panasonic networks. This protocol can be used to increase the PRI capability and enhance the ISDN by allowing two products to communicate with each other.

  • Voice Over IP
    The KX-TDA IP PBX system can be equipped with an optional VOIP card that permits you to connect the system to your existing data network providing an inexpensive alternative to route calls between two KX-TDA IP-PBX systems.

Digital Voice Mail Integration

The KX-TDA100 and the KX-TDA200 feature built-in software that digitally integrates the Panasonic voice processing systems. Thus providing proprietary high-speed communication between the PBX system and the voice processing system. There are 5 voice processing models to choose from, each containing a built-in auto attendant, interview service and voice mail.

SD card 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.

Caller ID/Call Logging

Caller ID displays the incoming callerís phone number, or name and number (if provided by the local phone company), when used with a Panasonic system display phone. The user at each extension can log up to 30 answered calls, while unanswered calls are logged automatically. Logged calls can be called back by going off-hook while viewing the INFO screen and pushing the redial key. There are also up to 1000 programmable entries of name and number for Caller ID service that can be administered by either the user or the system programmer.

Programming and Maintenance

Panasonic certified technicians have multiple password protected access points to program the system and perform maintenance. The system is equipped with a built-in RS232 and a USB port for onsite access. The system can also be set up so it can be accessed remotely via an optional dial up modem or through the Internet.


The KX-TDA100 and KX-TDA200 systems allow the user to have multiple conference calls from 3-party up to 8-party calls at the same time. This feature can prove to be quite beneficial for those who do a lot of conference calling within the same company and may otherwise need an external conference service.

Universal Call Distribution

Having Universal Call Distribution is an inexpensive alternative to adding an additional call center. With Universal Call Distribution incoming calls are evenly distributed to operators or agents logged into a specific UCD group, such as required by a travel office, customer support center, etc. Four different outgoing messages can be recorded and played back in a cycle, and a separate extension can be assigned for overflow calls. Members of a UCD group also have the capability to temporarily remove themselves from the group. This allows members to go to lunch or finish paperwork before taking another call. They can then return to the group when they are ready to answer calls.

Direct Inward System Access (DISA)

With the optional KX-TDA0191 4-Channel Message Card, the KX-TDA100 and KX-TDA200 systems allow an outside caller to access specific system features without operator assistance, as if the caller had an extension in the system. The outside caller can have direct access to the following features: single-digit access to extension, outside party calling, intercom calling to an extension, modem (for remote system administration), external pager, phantom extension and extension group. Additionally, callers can be required to dial a security code to access extensions or the systemís outside lines.

Telephone Application Programming Interface (TAPI) Compliant

TAPI compliance allows the user to connect their computer to the network system. It is a set of files and specifications for using telephony in a Windows environment. This standard program interface lets you and your computer "talk" to each other and there by allow integration of the telephone and computer systems over telephones to people or phone-connected resources almost anywhere in the world.

Account Codes

Account codes can help manage your telephone expenses by identifying incoming and outgoing external calls for accounting and billing purposes. The system can be programmed to force the use of an account code or not. The account code is appended to the Station Message Detail Recording (SMDR), which is very useful for billing back clients, or to simply keep record of the time spent on the telephone for a specific project.

System Speed Dialing

The KX-TDA100 and KX-TDA200 both provide up to 1000 tenant and 2000 system speed dialing numbers (24 digits long for each) for all extension users. Both the user and the system administrator can program system speed dialing numbers and names. Additionally, some models in the KX-T7600 series, such as the KX-DT346 and the KX-T7633 telephones, allow you to scroll through the speed dial list and simply hit the speakerphone key to dial the number. This feature can be used for both system and personal phone numbers.
