AN-E1-V35/AC

E1-V35 interface convertor, 75/120, 220V

AN-E1-V35/DC48

E1-V35 interface convertor, 75/120, DC-48V

Description

Provides safe and seamless connection between different devices with different interfaces.
Used widely in connecting WAN and LAN, video monitor. data interface is DCE, connnect with DTE or DCE. The main E1 link may be clocked from the recovered receive clock (LBT), from the data port, or from an internal oscillator. The G.703 port provides for either 75 Ohm unbalanced connection via BNC connectors or 120 Ohm balanced connection via RJ-45/48. The AN-E1-V35/V24 DIP and slide switches, located on the front panel, provide for easy setup and control of all functions.
