Taipei, Taiwan, Nov., 2008 ---The roadside emergency telephone is for use on public highways or private toll roads and can service remote areas where cellular systems are not commercially feasible. These phones are connected by twisted-pair cables to the service center. What the customer wants is to monitor each booth so engineers could immediately know if a booth was in use, in need of service, or being tampered with.

Emergency Phones are designed to provide quick and reliable hands-free communication over the public switched telephone network. The emergency phones were located at specific intervals along the highway. All booths were connected to an Ethernet network that ran the length of the highway. The JetCon 6350 12-Ch DI + 4-CH DO Smart Ethernet I/O Converter was chosen as a small control unit for each site. The JetCon 6350 provided simple local device control for the alarm light, which would be automatically activated when the emergency push button is pressed.
