Abstract

PURPOSE:To relieve the disconnection of fire and police lines at the time of emergency through radio repeating, by providing the titled device with a means to control between a pre-device and a post-device. CONSTITUTION:A signal is originated from a subscriber SUB to a fire station or a police station, an exchange LINK connects the SUB with a fire police trunk FPT and sends a calling tone to the SUB. An output signal repeater OGREP is started by the FPT and sends earth to a carrier device CEO. The CEO sends an originated signal to the opposite carrier device CEI, which sends earth to an input signal repeater ICREP. The ICREP sends a calling signal to a fire and police terminal TERM to detect its response and set up the communication line and sends earth to the CEI. Consequently the CEI sends a response signal to the CEO. The CEO sends earth to the OGREP and the OGREP sets up the communication line and sends a response signal to the FPT.
