Networking
If you are designing your company’s 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 system’s 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 company’s 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 vendor’s 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 you 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.

512MB 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 caller’s 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.

Conferencing
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 system’s 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-T7636 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.
