E1 to V.35

Overview
E1 to V.35 protocol converter can realize the bi-directional data transfer from E1 port to V.35. This equipment is widely used in communication network including WAN and LAN, realizing the transfer from E1 channel of SDH or PDH equipment to V.35 which maybe provided with router.
