E1 G.703 to V.24 Interface Converter
E1 G.703 to V.24 Interface Converter E1/T1 Interface Converter Series Interface Converters AD-Net Selangor, Malaysia, Kuala Lumpur (KL), Petaling Jaya (PJ) Supplier, Suppliers, Supply, Supplies | Catacomm Corporation Sdn Bhd


AN-E1-V24 E1/ V.24 converter provides physical level conversion between ITU-T G.703 standard E1 interface and standard V.24 interface, it can receive synchronous 2.048 Mbps data from E1channal and transmit the data to router, DDN, multiplexer or other equipment, thus providing secure and seamless communicating connection between equipments with different interfaces in the network. It is widely applied in the interface between WAN and LAN and in video monitoring. The pattern of data interface is DCE, which can be connected with DTE or DCE equipment.



  • Carefully designed electric circuit and entire hardware scheme can guarantee the reliability of this equipment, which basically does not adopt the special-purpose chip, and its production is not influenced by purchasing;
  • system has passed through strict test and practical confirmation, conforming to ITU-T V.24, G.703, and G.704 standard;
  • E1 interface options are 75Ω unbalanced or 120Ω balanced;
  • V.24 supports hot plug in support;
  • V.24 interface supports various kinds of clock source and timing for option;
  • provides four clock types: E1 master V.24external, E1master V.24 internal, E1 submissive V.24 external, E1 submissive V.24 internal;
  • V.24 interface can be tail-connected with other DCE equipment;
  • Provides 3 kinds of loop-return function, namely E1 self-looping at local end, V.24 self-looping at local end, and V.24 being ordered to self-loop at remote end (non- framing model not having this function);
  • AC220V and DC-48V power supply pattern may select, DC-48 and +24V power are not divided to positive and negative pole for simple installation and maintenance;
  • Supports function of pseudo-random code testing, which brings great convenience for installation, debugging and maintenance of equipment;
  • Working clock can support internal-clock, external-clock, and route clock;
