About This Product

STM-1J/STM-1 (OC-3) Convertor mutually converts STM-1J from PSTN such as NTT and STM-1 from overseas. STM-1J and STM-1 (OC-3) are equipped with 2 links of 0 system and 1 system, and in APS mode, these 2 links can be automatically switched by APS, and in Non-APS mode, both interfaces can be switched automatically. 0 series and 1 series can be used independently. It also supports redundant power supplies and remote monitoring using alarm contacts and SNMP. This device can be used to connect foreign-made media gateways and switches with Japanese PSTN and STM-1 (OC-3) interfaces when deploying IP telephone service networks.

■Main features

- Operates in slave synchronization with the STM-1J line using JT-G.811. - Can be switched to "Non-APS mode" which accommodates two lines that transmit K1 and K2 bytes, and "APS mode" which automatically switches two STM-1J lines and STM-1J line in a 1+1 redundant configuration. is. ・Has two systems of DC48V input power supply and operates in parallel. - Power supply abnormalities and line abnormalities can be easily confirmed using the lamp display on the front of the device. - Has a no-voltage contact terminal that shorts when an abnormality is detected. ・Detects various alarms generated on the STM-1J side or STM-1 (OC-3) side and issues alarms to the other side according to the alarm transfer specifications. - You can use SNMP to monitor device status and change line settings. - By using the attached software, you can upload firmware and reboot the device via the network.
