DLX-CON06 4E1 adopts demultiplexing technology, which binds several E1 circuits together to transmit 10M/100M Ethernet data, allowing certain transmission Timelag difference. It can extend the transmission distance and scope of application of Ethernet with existing E1 circuit resources of telecommunications network and is an ideal Ethernet broadband access solution.
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)
