The KH-CS series is a self-developed multi-link communication switching control module, which can provide a transparent transmission channel for IP-based multimedia services such as video, voice, and data. This product can be connected to various links including 5G, ad hoc networks, satellites, and wired networks, and automatically selects and switches links based on link quality. It also has a loop avoidance function to ensure the reliability of the communication link. This product has gigabit network communication capabilities and interfaces can be flexibly defined as WAN or LAN according to needs, meeting the requirements of multiple exits and multi-link backup for various services.

     The KH-CS series multi-link communication switching control module adopts adaptive link switching technology. Through dynamic real-time detection of different links, it realizes adaptive dynamic adjustment of primary and backup links, improving the anti-interference and communication reliability of the equipment and data transmission reliability. The module supports link priority sorting, switching threshold setting, and supports various link evaluation methods such as packet loss detection, interference detection, signal-to-noise ratio detection, and multi-value weighting. Through trend prediction based on the sliding window, a smooth and seamless switching process is ensured.
