Overview E3/t3-t is state of the art network termination units (ntu) connecting fast ethernet lans over e3 or t3 circuits. The devices enable service providers and isps to supply transparent. Ethernet services to remote locations over existing e3/t3 infrastructure. The devices can be used in a point-to-point application and widely used in lnteroffice or enterprise lan connection. E3/t3-t has one unframed e3 or one framed t3 port, and one 10/100basetx port. Packets are forwarded from the ethernet network to the e3 or t3 network at wire-speed, fully utilizing the expensive tdm circuit bandwidth. Features: * best price performance ethernet over e3 or t3 intelligent converter in the market * wire-speed forwarding fully utilizing the e3 or t3 circuit * vlan stacking and tagging enabling service providers to provide layer 2 transparent lan services while securing providers management * fault propagation of e3 or t3 error conditions to ethernet port * diagnostic collection on tdm and ethernet interfaces * comprehensive led indicators on front panel, convenient for the diagnosis of equipment working state * -48v dc & 220v ac power supply optional.
