FE1-V.35 Protocol Convertor

E1-v.35 convertor provide conversion between ITU-T G.703 standard E1 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.

• 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.

• Interface Rate: 2.048Mbps+-50ppm
• Line Coding: HDB3
• Interface signal coding: ITU-T G.703
• E1 Impedance: BNC 75Ω(unbalance) and RJ45 120Ω(balance).
• Interface character: match G.703
• Jitter tolerance: according with G.742 and G.823.

V.35 Interface

• Interface Rate: 2.048Mbps+-50ppm.
• Interface character: match V.35/V.24.
• Connector: DB25 male/female optional.
• Interface type: DCE.
• Clock: G.703 resume clock, internal /external clock.
