Framed E1-FE interface Converter JHA-CE1fF1 Overview This interface converter is based on FPGA,providing one framed E1 interface and one Ethernet interface to achieve 10/100Base-T Ethernet data transmission on the E1 channel. It is a high performance, self-learning Ethernet bridge. This device is the extension device of Ethernet, using network (PDH/SDH/Microwave) that provide E1 channel to achieve local and remote Ethernet interconnecting with serial interfaces at a lower cost. The device has inter-set loop test function to facilitate the project launching and daily maintenance. Product Photo   Mini  Type Features Based on self -copyright  IC  Can realize monitor and control of remote equipment, OAM management data did not  take up user’s timeslot and save E1 bandwidth E1 supports any timeslot set, the rate is 64K-2048K The local device can forced the remote device rate follow it Have the function of E1 interface loop back check, avoid the converter crashed because of interface loop return; Have indicator  when the device is power-off or E1 line is broken or lose signal; Can set the E1 line that not to send the LINK signal to Ethernet interface while E1 line is broken; The Ethernet interface supports jumbo frames (2036 Bytes); Inter-set dynamic Ethernet MAC address (4,096) with local data frame filtering  Ethernet interface supports10M/100M, half/full duplex auto- Negotination and AUTO-MDIX(crossed line and straightly connected line self-adaptable ); Have Ethernet monitor self-reset function, the equipment will not dead Can achieve the remote device setting any 5 mode of Ethernet and can closed the AUTO-MDIX function;  Provide 2 clock types: E1 master clock and E1 line clock; Have three Loop Back Mode: E1 interface Loop Back (ANA)、Ethernet interface Loop Back(DIG)、Command the remote Ethernet interface Loop Back(REM)  Provide 2 impedances: 75 Ohm unbalance and 120 Ohm balance; Support SNMP Network Management; Can realize monitor of remote equipment temperature and voltage from local equipment;   Can form the structure: Ethernet E1 Bridge(A)－－-E1 Optical Fiber Modem(B)－－-Ethernet Optical Fiber Modem (C)  Can form the structure: Ethernet E1 Bridge(A)－－-Optical Ethernet E1 Bridge (B)－－-Ethernet Optical Fiber Transceiver (C), can manage (B) and (C) at (A) Parameters ♦ E1 Interface Interface Standard: comply with protocol G.703; Interface Rate: n*64Kbps±50ppm; Interface Code: HDB3; E1 Impedance: 75Ω (unbalance), 120Ω (balance); Jitter tolerance: In accord with protocol G.742 and G.823 Allowed Attenuation: 0~6dBm ♦ Ethernet interface(10/100M) Interface rate: 10/100 Mbps, half/full duplex auto-negotiation Interface Standard:     Compatible with IEEE 802.3, IEEE 802.1Q (VLAN) MAC Address Capability: 4096 Connector:     RJ45, support Auto-MDIX ♦ Working environment Working temperature:    -10°C ~ 50°C Working Humidity:     5%~95 % (no condensation) Storage temperature: -40°C ~ 80°C Storage Humidity: 5%~95 % (no condensation) Specifications Model Model Number:JHA-CE1fF1 Functional Description 1channel framed E1 - FE converter ，N * 64k rate setting ，With E1 loopback detection function Port Description One E1 interface；1*FE Interface Power Power supply: AC180V ~ 260V；DC –48V；DC +24VPower consumption: ≤10W Dimension Product Size:  216X140X31mm (WXDXH) Weight 1.1KG/piece Application Typical solution 1 Typical solution 2 Typical solution 3
