About The System

We congratulate you on being a proud owner of the CORAL EX enterprise switch. This switch is available in configurations of 104 & 308 which means it is capable of handling from 1 to 3 trunks lines & 4 or 8 extensions. The EX series is designed for use in small or medium sized business organizations & in residential segment. The SWITCH uses a switch mode power supply, which ensures a stable power to your equipment. External CVT/Stabilizers must be installed in industrial areas or in any area, which faces large power fluctuations. The system has highly versatile software, which provides the user with a variety of features to suit one’s communication requirements. The Program changes & feature availability by any extension can be either enabled or disabled even at the site by certain codes. The use of low power components reduces systems power & cooling requirement. The system is easy to install and goes through stringent quality control to give you high reliability.
