CTC Union's "Tunnel Control" solution incorporates various devices that play different roles in layered tunnel control systems so as to ensure reliable services and minimized risk of potential accidents such as fire. For example, the use of bypass switch in a ring topology can provide redundant connections even when power failure occurs in a node. Furthermore, integrated EMS system automatically collects real-time data or messages sent from the devices placed in the tunnel to networking personnel who supervise and monitor tunnel traffic safety in the remote-control center.
With the adoption of total "Tunnel Control" solutions, the connections are always-on while transmitting data, and the optical connections make the transmission more secure over longer distances. Last but not the least, future maintenance or upgrades are more convenient and easier with point-and-click Web configuration pages.

Challenges

• ● The devices placed in tunnels may operate in harsh environments.
• ● In tunnel scenario, reliability and uninterrupted delivery of services is essential.
• ● The personnel who are in charge of tunnel safety in the remote-control center must take immediate actions when accidents occur.

CTC Union's Solution

CTC Union, one of the leading providers with abundant experience in providing network solutions, offers a comprehensive range of networking devices targeted at applications with rigorous safety standards. Our solutions are designed to enhance safety standards and integrate operational information into a centralized management system for future analysis or planning. Major features of the proposed network devices that are crucial to building up a tunnel control system are as follows:

• ● Network devices of tunnel control system are all IP products that are easy to connect to other devices and easy to upgrade for future network expansion planning.
• ● Network devices of IBP series provide signal bypass function when one of the node's power fails in daisy chain or ring topology.
• ● Network devices of IBP series support ring topology for redundant purposes.
