Framed E1-FE+8RS232 interface Converter JHA-CE1F1R8 Overview This protocol converter (interface converter) using large scale FPGA design, providing a framing E1 interface and an Ethernet interface and 8channel RS232/422/485,it is possible to achieve 10 / 100Base-T Ethernet data over E1 channels transmission, is a high performance, self-learning Ethernet bridge. The device serves as an extension of Ethernet devices, use of existing networks (PDH / SDH / microwave, etc.) provided by the E1 channels to interconnect both ends of the lower cost Ethernet and serial interfaces. Built-loop test equipment capabilities to facilitate the opening and routine maintenance works. Product Photo 19inch 1U 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 indicator  when the remote device is power-off or E1 line is broken or lose signal; Have the function of E1 interface loop back check, avoid the converter crashed because of interface loop return; The Ethernet interface supports jumbo frames (2036 Bytes); Inter-set dynamic Ethernet MAC address (4,096) with local data frame filtering function Ethernet interface supports 10M/100M, half/full duplex auto- Negotination, support VLAN Ethernet interface supports AUTO-MDIX (crossed line and straightly connected line self-adaptable ); Have Ethernet monitor self-reset function, the equipment will not dead Provide 2 clock types: E1 master clock and E1 line clock; Provide 2 impedances: 75 Ohm unbalance and 120 Ohm balance; Support SNMP Network Management Serial Data Interface can be RS232/RS422/RS485/TTL optional Serial channel can transmit adaptable serial data asynchronously 300 Kbps-19200Kbps baud rate Serial data multiplexing in E1 support ITU-T R.111 jumping coding mode The local RS232 serial data can command the remote RS232 serial data loop-back to the local. This loop-back in the outer ring of RS232 data interface, you can test the RS232 interface chip without damage Serial port interface lightning-protection reached IEC61000-4-5 (8/20μS) DM(Differential Mode): 6KV, Impedance (2 Ohm), CM(Common Mode): 6KV, Impedance (2 Ohm)standard 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 ♦ Serial Interface Standard   EIA/TIA-232 RS-232 (ITU-T V.28)   EIA/TIA-422 RS-422 (ITU-T V.11)   EIA/TIA-485 RS-485 (ISO/IEC8284)   Serial Interface   RS-422:TXD+, TXD-, RXD+, RXD-, Signal Ground   RS-485 4 wires: TXD+, TXD-, RXD+, RXD-, Signal Ground   RS-485 2 wires: Data+(Correspond TX+), Data-（Correspond TX-）, Signal Ground   RS-232: RXD, TXD, Signal Ground ♦ 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-CE1F1R8 Functional Description 1channel framed E1 -FE +8RS232/422/485 converter，With E1 loopback detection function Port Description One E1 interfaces, Eight data interfaces (RS232) Power Power supply: AC180V ~ 260V；DC –48V；DC +24VPower consumption: ≤10W Dimension Product Size:   19inch 1U type  483X138X44mm (WXDXH) Weight 2.0KG/piece Application
