Detailed Product Description
Overview:
Optostar's FE1-V.35 Protolcol Convertor provide conversion between ITU-T G.703 standard FE1 interface and standard V.35/V.24 interface, can convert E1 channel of SDH, PDH, and other Optical Transmission Equipment or microwave, satellite Equipment to V.35/V.24 channel, Extend V.35 channel of DDN. Used widely in data communication networks, Connecting with V.35/V.24 interface of Routers and Optical Transmission Equipments without G.703 interface, realize match between different network equipments, and transparent to upper protocol layer.
Main features:
◆ Realize monitor of remote equipment from local equipment( Having two row of LEDs, upper row indicate local status, lower row indicate remote status, unframing equipment have no this function.)
◆ Provide 4 clock types: E1 master V.35/V.24 external or internal, E1 slave V.35/V.24 external or internal.
◆ V.35/V.24 interface can connected with other DCE equipments.
◆ provide 3 loop functions: local loop, to remote loop, order remote loop.
◆ Power supply option: AC220V, DC-48V. The positive and negative terminal can be exchanged for DC-48V, easy for installation and maintenance.
◆ Have pseudo random code test function, easy the installation and maintenance.
◆ Realize rate setting of remote equipment (in slave clock status) when local equipment is in master clock status(unframing device haven't this function).
◆ Network manager interface use SNMP or RS485.
