    Two service classes

High quality, highly reliable, fully guaranteed bandwidth

Each circuit is allocated a fixed bandwidth to fully guarantee bandwidth, and robust security is provided.


Layer 3 and higher protocols are unrestricted, enabling wide-ranging usage.

Link-down transfer for assurance

The service has a link-down transfer function that automatically deactivates the user port link for the circuit terminating equipment in the event of a fault, thereby quickly notifying customers and minimizing the impact of the fault by switching the customer’s equipment to a backup route.

Two service classes

We provide two classes of service: a single type without a backup circuit and a dual type that includes a backup circuit for increased reliability.
