Application scenario:


E1 to 4 x V35 interface converter, 75/120, 220V


E1 to 4 x V35 interface converter, 75/120, DC-48V


E1 to 4 x V35 interface converter, 75/120, DC+24V


This converter provide conversion from ITU-T G.703 framing E1 interface to 4 x V35 interface provide safe and seamless connection between different device with different interface,option slot choice to compose N*64k(N=1-32) V35 channel.
Suitable for the case of available part slot of E1 channel and the device to transfer having only V.35 output. interface is DCE, can connect with DTE or DCE.
