Network Switches Ensure Always-On Connectivity for Toll System
Industry Application: Electronic Toll Collection (ETC)
The Vietnamese government is planning to implement an ETC system at all of the country’s toll booths to end delays and cut costs. Currently, the system is in effect at some booths on Expressways 1 and 14. An Ethernet network will be deployed at each toll collection station, with stations connected via a fiber network.
As part of the government’s infrastructure plans for road transportation, the planned ETC system will require high-quality and reliable industrial switches at each station in order to handle the aggregation and management of data flows from IP devices such as cameras and controllers at the station.
An important requirement of the project was that the network connectivity along the national highways had to remain alive and connected at all times, even in the event of switch failure. Furthermore, the system integrator of this project was looking for a reliable switch vendor that could provide excellent technical training and materials to shorten the learning curve of hired personnel.
Using EKI-7710E-2CI: DIN-rail managed layer-2 switch with two Gigabit combo uplinks and LAN bypass
- At each toll collection station, all IP devices are connected to an EKI-7710E-2CI via an Ethernet interface
- Two Ethernet-fiber media converters are connected to each of the EKI-7710E-2CI switches’ uplink ports, thereby extending the distance for fiber connectivity, and all stations are connected via fiber
- The built-in LAN bypass feature in EKI-7710E-2CI switches can automatically bridge data transmission from IP devices to media converters in the event of switch failure, thus guaranteeing 100% network connectivity at all times
