VOS-08 is an Interface transducer of 8 E1/ETH, which can enable the high-speed data transmission of 1~8 E1 to Ethernet to satisfied the users' demand of high Rate of Transmission.
At the same time, the lines of E1 are integrated and independent from each other so there is something wrong with one of 8 lines of E1, the other 7 lines can still work to ensure the durative communication of E1.
