Overview: E1 to V.35/V.24 (provides conversion between E1 and V.35/V.24 interface)
Product introduction:

E1 to V.35/V.24 converter provides physical level conversion between ITU-T G.703 standard E1 interface and standard V.35 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.
Features:
the E1 to V.35 converter/V.24 conforming to ITU-T V.35, G.703, and G.704 standard;
E1 interface supports 75ohm unbalanced or 120ohm balanced;
V.35 supports hot pl ing;
V.35 interface has many kinds of clock source and timing for option;
provides four clock types: E1master V.35/V.24external, E1master V.35/V.24internal, E1submissive V.35/ V.24 external, E1 submissive V.35/ V.24 internal;
V.35/ 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.35 self-looping at local end, and V.35 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;
has the function of pseudo-random code testing, which brings great convenience for installation, deb ing and maintenance of equipment;
