2. Overview 2.1 Introduction The LR0301A 1-Port T1/ E1 Network Extender (LR0301A-KIT) is an Ethernet extender that converts protocols and data from Fractional T1/E1 to Ethernet 10BASE-T/100BASE-TX interfaces. It’s a symmetrical broadband solution for Intranet LAN-to-LAN connection with Nx64kbps bandwidth. The pair of extenders included with this kit acts as a bridge, enabling you to link two Ethernet networks across T1/E1. -
