Cost-effective Way for Emergency Roadside Telephone Application, IES-2042FX & IES-3062FX

An emergency roadside telephone system consists of several self-powered, emergency telephone terminals located at remote sites to enable communications with a central station for emergency assistance when an accident occurs. The emergency phones are placed at specific intervals along the road and each phone is connected to an IES-2042FX industrial Ethernet switch. These lite-managed switches are linked over fiber networks and can be managed from the control center.

Many of IES-2042FX industrial Ethernet switches were deployed with a distance of 2km from each other. To ensure high availability and reliability, the switches were installed in ring topology. As a result, data will continue to be transmitted to the control center when a device in the loop fails. At the control center, an Ethernet backbone built with the IES-3062FX managed industrial Ethernet switch enables communications with roadside IES-2042FX. With more advanced management capabilities, the IES-3062FX allows the administrator to manage the switches easily using Web-based, Telnet, Console, or CLI interfaces. The administrator can also increase the bandwidth between two Ethernet switches using the port trunk function of the IES-3062FX. By grouping several ports together to function as one logical path, the bandwidth between switches is increased, which is particularly useful during peak hours when the traffic load is heavy
