HTD E1-Ethernet protocol converter is a single E1 port with Ethernet Bridging that provides high-speed LAN-to-WAN connectivity. Plugging directly into the 10/100Base-T port of a hub or LAN switch, the E1-F provides E1 access at connection data rates of 2.048 Mbps. The E1-F is an excellent choice for Internet access as well as LAN-to-LAN services.

HTD E1/ V.35 protocol converter provides physical level conversion between ITU-T G.703 standard E1 interface and standard V.35 interface, it can receive synchronous 2.048 Mbps data from E1channal and transmit the data to router, DDN, multiplexer or other equipment, thus providing secure and seamless communicating connection between equipments with different interfaces in the network. It is widely applied in the interface between WAN and LAN and in video monitoring. The pattern of data interface is DCE, which can be connected with DTE or DCE equipment.
