Quick Facts - Kit includes two extenders. - Bridges 10BASE-T/100BASE-TX Ethernet across a single T1/E1 line. - Support speeds up to 1.544 Mbps on T1 and 2.048 Mbps on E1. - Supports Fractional E1/T1 in framed and unframed mode. Further Details - Autosensing, autonegotiating 10-/100-Mbps LAN connections. - Auto MDI/MDI-X means you never need a crossover cable on the Ethernet side. - DIP switches make configuration easy. - Line build-out (LBO) capability. The pair of extenders included with this kit act as a bridge, enabling you to link two Ethernet networks across T1/E1. Because you're using leased lines provided by your telco, there are no distance limitations—you can extend your network anywhere you can get a T1 line. The T1/E1 Ethernet Network Extender converts protocols and data from Fractional T1/E1 to 10BASE-T/100BASE-TX Ethernet and supports both framed and unframed modes with line codes. The extenders are easy to install—just connect them then configure them using simple DIP switches.
