The tunnel emergency IP Telephone Broadcasting System is an integrated communication platform which combines the emergency telephone and cable broadcasting launched by Yuantong Company, that is, emergency telephone and cable broadcasting share one set of software (the same operation screen for alarm and broadcast and access to Ethernet three-layer switch, other subsystem of data request support or linkage) , share the transmission network, they are functionally independent of each other and do not affect each other. That is, the two share a host, a transmission cable, and an optical interface, which can effectively utilize and save system resources, but they are functionally independent of each other and do not affect each other, the caller can call the police and communicate with the on-duty staff of the center. The on-duty staff can also monitor the tunnel broadcast by using the on-call and off-call function of the emergency telephone.
