Cost-effective Way for Emergency Roadside Telephone Application

HSIN TIEN, Taiwan - March 20, 2015 - PRLog -- Taipei, Taiwan, March 20, 2015－
When an international Electronics Design company was looking to install emergency roadside telephone solutions in India, they hoped to build a network that would not only provide fast warnings to emergency services in the event of an accident, but also to ensure reliable communications for the public in the case of accidents or breakdowns. This road serves as a major role in the daily commutes of thousands of passengers. Considering the heavy traffic of the road and high temperature in India, especially in the summers when the temperature may exceed 40°C, it needed a solution that would continue to work in difficult environmental conditions.

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.
