V Serial Interface Converter

Unframed E1-V.24 Converter

This series of equipment provides a non-framing E1 interface and a V.24 interface enabling non-framing E1 to V.24 interface between the conversion the user can use the data channel rate of 2.048Mbps. Equipment built-in loop test function for the project opening and routine maintenance to facilitate.
◆ based on independent intellectual property rights of integrated circuits;
◆ While supporting the adaptive 120Ω / balance and 75Ω / unbalanced two kinds of impedance no longer set;
◆ The system undergoes rigorous testing and practical verification in full compliance with ITU-T V.24 G.703 G.704 and other recommendations;
◆ There are three loopback functions: E1 local loop (ANA) V.24 ring (DIG) so that the end of V.24 from the ring (REM);
◆ Pseudo-random code test function easy to open the line that can be used as a 2M error meter to use;
◆ V.24 interface supports hot swapping; support and DTE or DCE device interconnection;
◆ V.24 working clock can support internal clock external clock line clock;
◆ Optional AC 220V DC -48V DC +24 V DC power supply without positive and negative points.
