A clear explanation of the termination of general-purpose high-speed digital transmission services and the transition methods utilizing existing equipment.
Are you able to confirm the communication environment of the equipment in preparation for the termination of the dedicated line services by NTT East and NTT West? The "General Dedicated Service" and "High-Speed Digital Transmission Service" are scheduled to end on March 31, 2029. In facilities such as water treatment plants, pumping stations, intake facilities, factory utilities, environmental monitoring and weather observation, and power facilities and substations, remote monitoring and control systems utilizing dedicated lines may have been in operation for a long time. On the other hand, for equipment that has been in use for a long time, there may be challenges such as: - Not knowing which equipment is using dedicated lines - Not knowing the manufacturer or model of the telemetry - Unable to determine whether to update the equipment or if only the line can be changed - Concerns about increased costs due to complete updates - The possibility that monitoring and control may become impossible in the future if the current situation remains unchanged Please use this information as a reference when considering future communication updates, especially if you are unsure whether dedicated lines are being used or if you cannot determine how much of the existing equipment can be retained.
