Converters for interfacing teleprotection equipment with IEEE C37.94 or optical E1 ports to communication networks using electrical E1. It can convert single and dual/quad C37.94 or optical E1 to electrical E1 interface. The IEEE ports are fully mapped into G.703 standard frame structure of the E1 port, allowing for further SDH/ PDH multiplexing and de-multiplexing. Successfully connect with line differential protection relay of Toshiba, GE, AB, Siemens, SEL,…
