1 GENERAL INFORMATION

Model BD-E1-ETH is a single port E1 with Ethernet Bridging that provides high-speed LAN-to-WAN connectivity. Plugging directly into the 10/100Base-T port of a hub or LAN switch, the E1-ETH provides E1 access at connection data rates of 2.048 Mbps. The E1-ETH is an excellent choice for internet access as well as LAN-to-LAN services 2 PRODUCT CHARACTERISTIC  Based on self-copyright IC.  Ethernet port 10/100M half/full duplex self adaptable, supporting VLAN.  RJ45 interface supports AUTO-MDIX.  Provides 2 clock types: E1 master clock, E1 line clock.  Provide LAN auto reset function, run more stably.  Has the function of pseudo-random code testing, convenient for opening of the circuit, and can be used as an error code instrument.  Have three Loop-Back Modes: E1 interface Loop-Back (ANA)、LAN interface Loop-Back (DIG)、command the remote LAN interface Loop-Back (REM) .  E1 connector support (BNC)75ohm/(RJ45)120ohm adapt ;  With abundant presentation function of Ethernet data, can detect real-time data communication status.

3 ENVIRONMENT REQUIREMENT

The temperature requirement is not very strict, the device can be working well under terrible environment.  working temperature: 0°C - 50°C  relative humidity: 95%(without coagulation)  No erosive and impregnant gas, no rising dust, no strong magnetic field disturbing 3.1 Power Adapting module power, voltage range can be wide, with strong ant-jamming function. With good insulation, stable working status is available  power: -48V type, input voltage: -36V～-72V  power: 220V type, input voltage: 90V～260V 3.2 Power consumption Total device consumption: <5W 3.3 E1 Interface  Line Rate: 2.048Mbps±50ppm  Line Code : HDB3  Interface Standard: ITU-T G.703  E1 Impedance : 75Ω(unbalance) and 120Ω(balance)  Connections :BNC and RJ45

 Jitter tolerance : finer than G.742 and G.823

3.4 10/100Base-T Interface Rate: 10/100M, full/duplex auto-negotiation Protocol: Support IEEE 802.3, IEEE 802.1Q (VLAN) MAC Address Entiries: 4096 Entiries Total Memory Sizes: 64MBits SDRAM Physical interface: RJ45, support AUTO-MDIX 4. DIMENSIONS 210(W) × 140 (L) x 30(H) mm 5. CONFIGURATION AND OPERATION 5.1 Display of the front panel

5.2 LED Indicator

There are 7 indicator LED on front panel. From left to right is as following: Name Color Status Description DAT green flick E1 port has date receive and transmit On/off E1 port has no date receive and transmit LNK yellow Flick/on Indicates Ethernet has connected off Ethernet has no connect LOS red ON E1 signal loss OFF E1 signal normal LOF reserved TEST yellow ON Under test status(ANA, DIG, REM, PATT pressed any) OFF In normal working status PTOK green ON PATT pressed, PATT test normal OFF PATT pressed, PATT test not normal Wink PATT pressed, PATT test has error code PWR green ON Power ON OFF Power not ON 5.3 loop-back button There are four loop-back button on the front panel, they are as following from the left to right, ANA: E1 Interface local-back loop, to check whether local device and its connecting circuit correct

DIG: 10/100BASE-T Local loop-back, to check the opposite device and E1 circuit

REM: E1 interface loop-back outward to test E1 line PATT: PBRS test. To produce and transmit the PBRS to the 10/100BASE input connector, and to check whether the output signal of the 10/100BASE accord with PBRS standard. If according, the PTOK light on, otherwise, off. By this way, the status of E1 Line can be tested. Push the PATT button, when loop circuit 1 is on, If PTOK is on , indicates device works well ; loop circuit 1 off and loop circuit 2 on, indicates that fiber transmission circuit and both side device work well E1 LINE PBRS Code REC & CHK E1 Interfa ce E1Int 10BInt When testing, one of above loop back must be on Loop 1 Loop 2 E1 line

 when the test LED on, the normal communication will be terminated

 During the PATT model testing, the circuit should be cycle by itself, otherwise, the PATT code can’t come back. 5.4 Display of the rear panel Rear panel（AC 220V） Real panel（DC -48V） Power of AC220V/ DC-48V is suitable for the device. If the power of DC-48V is used, the positive and negative terminal can be optional because there is the self-test circuit for the polarity inside the device. Note: TX —— E1 75Ω unbalance/120 balanceΩ, Transmit BNC/RJ45 Interface RX —— E1 75Ω unbalance/120 balanceΩ, Receive BNC/RJ45 Interface 10/100Base-T —— 10/100Base-T Interface, RJ45 5.5 Dial code in the panel On the panel, there are 8 digital DIP switches to set E1 clk.
