Description

 FE1/10&100Base-T Bridge is designed based on ASIC chip, the chip adopts jitter reduced, digital phase locked and clock distilled, E1 anti-jamming technology. The inner software and hardware are of modular design, integrating coding, decoding, message insertion and alarm, and make the circuit simple so as to improve the reliability of the device.

 FE1/10&100Base-T Bridge provides 64K~2M bandwidth data transmission channels for Ethernet over E1 lines, connects two LANs by PDH devices etc. It is suitable for many situations, such as LAN expansion, networks isolation, WAN access, it can connect Ethernet to telecom transmission network, Special network or WAN.

Special Features

Framed E1, data rate 64K~2.048Mbps is adjustable

Support the transmission of IEEE 802.1Q VLAN frame and maximum 1536Byte VLAN frame

DHCP packet filtering function can be enabled/disabled

Inside 32Kbyte MAC address memory space in the device, it can learn MAC address and refresh the list automatically

Inside up to 16Mbit register, features high data store-and-forward capability

Offer an Ethernet interface 10/100M, Full/Half duplex auto-negotiation

Offer MDI/ MDIX two Ethernet interfaces

Jitter tolerance and jitter transmission characteristic of E1 channel have high performance, which is superior to industry standard
