Introduction

MODEL7221 converter provides conversion between ITU-T G.703 standard E1 interface and standard V.35 interface, can convert E1 channel of SDH, PDH, and other Optical Transmission Equipment or microwave, satellite Equipment to V.35 channel, Extend V.35 channel of DDN. Used widely in data communication networks, Connecting with V.35 interface of Routers and Optical Transmission Equipments without G.703 interface, realize match between different network equipments, and transparent to upper protocol layer.
