The TDMA True 2 Timeslots trunking technology can dynamically allocate the spare timeslots to the groups that need to talk, easing the communication pressure when multiple groups are communicating at peak times. 2 timeslots communication allows communication to flow smoothly in real time during peak services or emergencies<\/p>\n<ul>\n<li>\n<h4>Digital\/Analog Smooth Transition<\/h4>\n<\/li>\n<\/ul>\n<p>BF-TD511EX supports both digital and analog modes that can receive digital and analog signals at the same time to compatible analog and digital modes, guaranteeing a smooth transition from analog to digital mode and reducing customer costs.<\/p>\n<ul>\n<li>\n<h4>Voice Encryptions<\/h4>\n<\/li>\n<\/ul>\n<p>Thanks to the ARC\/AES256 advanced encryption technology, BF-TD511EX provides rock-solid encryption to every communication, preventing sensitive information leakage or eavesdropping during transmission and guaranteeing communication privacy and security.<\/p><\/div>\n<div>\n<h4 style=\"text-align: center;\">Specifications<\/h4>\n<ul>\n<li>\n<h4>General<\/h4>\n<\/li>\n<\/ul>\n<table border=\"0\" cellspacing=\"0\"
