Nhận xét
MW80E4 là bộ chuyển đổi unframed E1 sang 04 port FE của hãng UPCOM. Thiết bị được thiết kế dựa trên nền tảng công nghệ FPGA. MW80E4 cung cấp sự chuyển đổi giữa chuẩn giao diện E1 ( ITU-T G.703 (E1)) và giao diện 10/100Base-T. Đây được coi là một Ethernet bridge và được thiết kế nhỏ gọn với chi phí thấp. Hiện nay, thiết bị được sử dụng rộng rãi trong việc kết nối giữa mạng WAN và LAN, hoặc trong các bài toán giám sát,...
Tính năng sản phẩm:
1. Based on self -copyright IC
2. E1 supports any timeslot set, the rate is 64K-2048K
3. Can realize monitor and control of remote equipment,OAM management data did not take up user’s timeslot and save E1 bandwidth
4. Have the function of E1 interface loop back check,avoid the converter crashed because of interface loop return;
5. Have indicator when the device is power-off or E1 line is broken or lose signal;
6. Can set the E1 line that not to send the LINK signal to Ethernet interface while E1 line is broken;
7. The Ethernet interface supports jumbo frames (1916 Bytes);
8. 4Channel 10M/100M Ethernet interface can isolate each other to realize communication independently;
9. Ethernet interface supports 10M/100M, half/full duplex auto-Negotiation and AUTO-MDIX (crossed line and straightly connected line self-adaptable );
10. Provide 2 clock types: E1 master clock and E1 line clock;
11. Have three Loop Back Mode: E1 interface Loop Back (ANA)、Ethernet interface Loop Back(DIG)、Command the remote Ethernet interface Loop Back(REM)
12. Have pseudo random code test function, easy the installation and maintenance;
13. Provide 2 impedances: 75 Ohm unbalance and 120 Ohm balance;
14. Have Ethernet monitor self-reset function, the equipment will not dead
15. Ethernet interface supports the counters of receiving and transmitting frame, receives wrong frame counters.
16. E1 interface supports the counters of receiving wrong frame;
17. Realize monitor of remote equipment temperature and voltage from local equipment;
18. Support SNMP Network Management;
19. Can form the structure: Ethernet E1 Bridge(A)---E1 Optical Fiber Modem(B)---Ethernet Optical Fiber Modem (C)
