Product Description
FE1 to V.35 converter provide physical conversion between ITUT G.703 standard E1 interface and standard V.35
interface and offer security and seamless link for communication between different devices with different interfaces. It can take out specified time-slots from G.703 E1 to compose V.35 channel of n*64K(n=1~32), suit for occasion that partial time-slots in E1 channel of transfer device can be used, and the device to transfer data only have V.35 output. Data interface mode is DCE, can connect with DTE or DCE device.
