E3 to ethernet converter, T3/ DS3 to ethernet converter: IC-E3T3L
Description

Fast Ethernet LANs over E3 or T3/ DS3 Converter

Introduce

Overview
IC-E3T3L is state of the art Network Termination Units ( NTU) connecting Fast Ethernet LANs
over E3 or T3/ DS3 circuits. The devices enable service providers and ISPs to supply transparent
Ethernet services to remote locations over existing E3/ T3/ DS3 infrastructure.

The devices can be used in a point-to-point application and widely used in lnteroffice or
enterprise LAN connection. IC-E3T3L has one unframed E3 or one framed T3/ DS3 port, and one
10/ 100BaseTx port. Packets are forwarded from the Ethernet network to the E3 or T3/ DS3
network at wire-speed, fully utilizing the expensive TDM circuit bandwidth.

Feasures
* Best price performance Ethernet over E3 or T3/ DS3 intelligent converter in the market
* Wire-speed forwarding fully utilizing the E3 or T3/ DS3 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/ DS3 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
