In 2024, the main synchronization means of the public circuit network will be discontinued. NTT has announced that it will end the provision of ISDN services in January 2024. With the termination of ISDN services, network synchronization (clock) signals will no longer be available, so we must prepare something new to replace the network synchronization signals. Radio broadcasting operators currently using ISDN services are encouraged to consider the digital audio synchronization transmission device 'RFD Sync-A300', which can utilize IP packet communication networks (fiber optic services).

The RX64M (manufactured by Renesas Electronics), equipped with IEEE1588 functionality, is a device that easily enables daisy chain wiring. By implementing our PTP software on the RX64M, which has two Ethernet ports, it can also function as a BC (Boundary Clock). Synchronization signals of 51.2KHz, 102.4KHz, 204.8KHz, 409.6KHz, and 819.2KHz, necessary for sensor control, are generated using a PLD. Please realize the construction of various sensor networks that leverage the features of the RX microcontroller capable of daisy chain configuration through the implementation of PTP software for the RX family.

The public circuit network time synchronization solution helps build a wide-area time synchronization network that does not rely on GPS. It can connect to devices that implement PTP functionality compliant with the IEEE1588-2008 standard.

• VPN/Wide Area Ethernet

An environment has been developed to provide high-precision time information within the network. This time information is mainly used for the synchronized operation of devices and equipment. Currently, it is rare for humans to receive this information. However, in specific business applications, there may be cases where the existing time synchronization features, which allow for second-level errors, are not acceptable. This product displays the time within a PTP network. Since it shows time information from a GPS-synchronized grandmaster, it provides extremely accurate values. Regular time adjustments are also unnecessary. Additionally, it monitors the normal/abnormal operation of PTP. It can be utilized for the primary analysis of issues that occur within the PTP network. This product complies with the international standard IEEE1588-2008.

• Other network tools

It is an evaluation, verification, and operation tool that conforms to the IEEE1588 standard PTP network and is used on Windows PCs. It consists of configure (configuration settings), state viewer (status display), sync viewer (synchronization accuracy display), among others, and has high versatility. It can be used in network systems with multi-vendor configurations.
