6 º Terminal Operator

The 6th terminal operator is the most difficult to handle due to the variety of services offered, traffic channels, and call distribution. It has a greater number of function keys, other terminal extensions, and a large display that takes advantage of the exchange. It came with the PBX to manage the exchange well and has a higher cost than any other type of terminal. It did not exist in KTS systems.
