The HGBT/AT-GZ series fiber optic emergency phone master unit is a transmission device customized for special applications such as tunnels and integrated utility corridors, based on fiber optic ring network technology. Its primary function is to transform the traditional communication cable wiring into fiber optic star or ring network wiring. By using the fiber optic emergency phone master unit as an access node, the auxiliary units are registered centrally to the core integrated communication server, creating an advanced audio-video scheduling communication system based on the GNG mode. The system employs the standard SIP 2.0 protocol, new industrial-grade optical modules, and supports both star or ring network configurations.
Directly connectable to Ethernet, supports cross-subnet and cross-router connections, and can transmit via fiber optics (single-mode, multi-mode).
