Description

HDSL is ASIC-based 2-wire 2.3Mbps Ethernet bridge SDSL modem. It uses SDSL(multi-rates digital end-user line) technology so that the data rate between two joint LANs can reach 2320 Kbps, the distance can be reached 3.29km in 24AWG(0.5mm) communication line and 2.51km in 26AWG(0.4mm) communication line. The modem can connect two LANs through a pair of twisted-pair to extend distance of LANs. With low cost, simple operation, and convenient use, it is suitable for cost-sensitive bridge connection or in LAN as stretcher or subsection. Ethernet conforms to standards of IEE802.3u and IEE802.3 and its speed rate is 10/100BaseT self-adaptive.

It can be installed and connected conveniently. One can use the dial switch on rear panel to setup work mode and transmitting speed rate, then connect cable to put it in use. There are many indicators on the front panel to display work states and line status of equipment.
HDSL is a high-performance self-educated long-range Ethernet bridge. It can receive frame in MAC net-bridge of LAN and carry out transparent transmission of MAC addresses. It can store a maximum of 1024 MAC subnet address. HDSL can learn automatically MAC address in the connected LAN and only transmit the target address to frame in another LAN.
