TACT TA-4800 RADIO/TELEPHONE INTERCONNECT
INTRODUCTION
TACT, the Telephone Access Control Terminal, interconnects a two-way radio system to a telephone line or
PABX extension. It allows you to make and receive telephone calls on your two-way radio mobiles and
hand-helds. Other features include paging, alarm and telemetry facilities.
Design Two Thousand Pty Ltd, established in 1968, has been making TACT units since 1987, and this TA-
4800 is the new flagship model. It is the digital successor to the well-proven TA-7. Here you have the option
of dialing telephone numbers using the TA-4800 in the same way as the TA-7.
Things that make the new TA-4800 unique are full remote programmability without the need for a modem,
real voice prompts to the user, and the many advantages of digital signal processing.
