GENERAL INFORMATION: The E1 converter is a single port E1 to Ethernet converter,which realizing G.703 to Ethernet protocol converter. Plugging directly into the 10/100Base-T port of a hub or LAN switch, the E1-ETH provides E1 access at connection data rates of 2.048 Mbps. The E1-ETH is an excellent choice for internet access as well as LAN-to-LAN services.
