The Communication Equipment Division provides a customer support tool that leverages cloud technology (AWS).
By continuously monitoring the operating status of equipment remotely and detecting early signs of trouble, we help ensure stable and reliable operation for our customers.

Traditionally, support activities have been primarily “reactive”, where remote assistance is provided after a problem occurs in equipment or systems.
However, with the widespread adoption of IoT and cloud technologies, it is now possible to monitor and analyze equipment at various sites in real time.
As a result, a proactive support approach—one that predicts issues and acts ahead of time—is increasingly required.

We utilize SSH (Secure Shell), a secure communication protocol, specifically its remote port forwarding function, to enable cloud-based remote maintenance.

■System Overview

Administrators access a remote maintenance portal hosted on AWS, then establish a secure communication path (SSH tunnel) to devices within the customer’s network via AWS.
This mechanism allows maintenance to be performed safely through the cloud without directly connecting to the customer’s internal network from the outside.

■Key Features

・Secure Communication Path
　SSH encryption protects communication content, ensuring secure remote connections.

・Safe Integration with Closed Networks
　No need to open firewall ports in the customer’s network, allowing existing security policies to remain intact.

・Rapid Troubleshooting
　Immediate remote access for status checks, log retrieval, configuration changes, and more.

・Flexible Operation
　Centralized management of multiple sites and devices through the AWS-based portal.

The proactive support framework developed in our Communication Equipment Division—designed to prevent problems before they occur—is also being considered for application in our Machine Tools Business.
By visualizing machine conditions via the cloud and detecting early signs of abnormal behavior, we aim to enable stable operation and quicker responses.
This shift transforms support from the traditional “fix after failure” approach to a preventive model, helping customers maintain their equipment in a safer and more reliable environment over the long term.
