- Model：LD4108
- Function of Product:
-
8E1/10&100Base-T Bridge is designed based on ASIC chip, and realize Ethernet data access over E1 channels. Ethernet data can be transmitted through up to 8E1 channels, which break through the single E1 bandwidth limit, easy to utilize the existing E1 resources in the public networks to quickly build up broadband Ethernet network. The device is no special request and can accept errors automatically for E1 channels, even though part E1 channels failed, the device will only decrease the throughput but not interrupt the data transmission.
-
1. Adopt large scale integrated chip, simple circuit, low power consumption, high reliability .
2. Offer an Ethernet interface 10/100M, Full/Half duplex auto-negotiation .
3. Provide 1~4E1 channels, easy to maintain .
4. Optimized delay design, ideal for H.323 video conference system .
5. Over-size buffer memory prevent over-size Ethernet packet losing .
6. Complete alarm and status indicators and loop back test functions .
7. Support the transmission of IEEE 802.1Q VLAN frame and maximum 1536Byte VLAN frame
8. Full E1 interface's physic configuration is convenient for field connection
9. E1 channels online auto-error-monitor, shut this channel transmission beyond 10-6 error
10. The circuit is designed simply, the device works steadily
