404EL 8 Mbps Inverse Multiplexer
404EL is a 4 E1 inverse multiplexer enabling the transport of high speed data broadband services over the 1 to 4 E1 links. Using G.704 and G.8040 standard to convert Ethernet to multiple E1 by GFP format mapping, 404EL supports minimum 1.984Mbps and Maximum 7.936Mbps. If any E1 drop or errors count is too big will not influence the bandwidth automatic adjustment 10/100/1000 Base-TX or fiber LAN interface make 404EL is an ideal solution for high speed broadband application. The inverse aggregation bandwidth is scalable as Nx1.984 Mbps [N=1~4] with maximum payload bandwidth at 7.936Mbps.
404EL can be managed locally by connecting a VT-100 emulated PC to the CID port or remotely through Telnet/SNMP access all on front panel of the unit. Administration, Maintenance, and Provisioning (OAM&P) are provisioned with the use of 16Kbps embedded operation channel (EOC) that runs through the inverse link. Configured with individual IP address for local and remote unit, 404EL is accessible to the Internet users who are managing the units from a far end place.
To ensure operation continuity and accommodate field requirement, 404EL offers choices of AC or DC or AC+DC power.
