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