ITB 302 Evo
AEV
₦ 2,424,149.00 VAT excl.
It is designed with two hybrid telephone cards, for easier management for multiple telephone line connections.
The main operating functions are controlled by a Remote Control keyboard, connected to the ITB-3O2 Evo with an ethernet network cable. Each channel is also equipped with a double RJ11 port, so it is possible to connect two lines for each channel and choose which of them to use from the menu on the display, avoiding manual exchanges, for example a GSM Box can be connected in combination with a fixed line, a GPIO port on the back provides the interface to other systems.
Multiple ITB-3O2 Evo units can be interconnected to allow expansion to "n" lines while maintaining ease of use. The ITB Console unit is available to manage the control of 8 to 16 telephone lines with a single control panel. The telephone lines, suitably filtered and isolated, allow audio conferences between them and the operator.
An internal microprocessor provides a range of functions that, until now, were difficult to provide in the same unit.
All potentiometers have been eliminated, thus solving any wear problems.
