原因何在 Super secure critical connectivity？

The CSL Router connects to CSL’s private mobile APN network, establishing secure internet connectivity on sites where wired broadband is either unavailable, impractical, or slow.
CSL offers a dual SIM variant that uses two separate mobile providers, ensuring the highest possible availability over a mobile connection. CSL also provide a 4G backup option, which serves as an upgrade to your existing broadband service, delivering a secure private network connection. This solution includes a mobile backup to safeguard against interruptions in wired broadband, providing continuous connectivity for critical connections.
CSL Router and CSL Back-up Router are available as a self-monitoring or as a ARC-monitored solution. Remote access is enabled via Cisco AnyConnect providing a secure direct connection to any device connected to one of our routers. All router variants arrive pre-configured for quick installation and are supplied with the appropriate monthly data SIM bundle to help manage costs.
