4e1 to Eth Ethernet Protocol Converter (TBC-FE6012)

4E1 Ethernet Converter (TBC-FE6012)

Features

*Supporting transparent transmission of Ethernet data over 1 to 4 E1 circuits
*In compliance with IEEE 802.3 protocol, supporting 10M/100M, full-duplex/half-duplex working mode
*Supporting transparent transmission of jumbo frames specified in IEEE 802.1Q, and supporting Ethernet switch with VLAN function
*Built-in dynamic Ethernet MAC address list (1024) in the chip, supporting local data frame filtering function
*Built-in Ethernet data frame FCS check functional module, with check alarm output
*Built-in Synchronous Dynamic Random Access Memory (SDRAM) controller
*Optional butter area size to suit different types of services
*E1 interface complies with ITU-T G. 703, G. 705, and G. 823 recommendations, but does not support the use of signaling timeslot
*Built-in clock recovery circuit and HDB3 coding/decoding circuit in E1 interface module
*Supporting HDB3 code pattern
*Supporting availability detection and automatic fault handling for 1 to 4 E1 circuits
*Perfect line alarm indication and output
*Supporting the reset of a remote system from a local system
*Supporting E1 circuit loopback function
*New peer end alarm function, enabling the user to remove faults visually
*New lightning protection function, effectively preventing the threat of thunders and lightning on communication equipment
*Supporting remote alarm function, enabling a network administrator to judge a remote E1 line fault from the local end (applicable to the carrier-class NE-2708D)
*MTBF > 50, 000 hours, in compliance with carrier-class operation requirements (applicable to the carrier-class NE-2708D)
