E1 T1 LAN GW

Description

408EL 16 Mbps Inverse Multiplexer

408EL is an 8E1 inverse multiplexer enabling the transport of high speed data broadband services over the 8E1 links. Using G.704 and G.8040 standard to convert Ethernet to multiple E1 by GFP format mapping, 408EL support 16Mbps.

408EL 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, 408EL is accessible to the Internet users who are managing the units from a far end place.

To ensure operation continuity and accommodate field requirement, 408EL offers choices of AC or DC or AC+ DC power.
