Bridging the
communication gap TODAY computers have revolutionised the whole world with amazing graphics, high-end data processing and above all, networking. Networking has become an essential component of any organisation for enhancing the output at a low cost. Local Area Networking (LAN) and Wide Area Networking (WAN) are widely prevalent and important tools of networking. LAN is confined to single building or a group of buildings and WAN is one LAN connected to other LANs over any distance via telephone lines and radio waves. The largest WAN in existence today is the Internet. LAN and WAN could be done on other networking components like UTP ( Unshield Twisted Pair) by enabling HUB over the network, fibre optic cable or using radio modem at a regular frequency. The basic problem faced by the network administrators is to connect or link two networks effectively and quickly at an inexpensive cost. The above said technologies have their own limitations viz.: 1. After every 100 meters the UTP cabling requires hub for further amplification of data on the network. Clamping of connectors, cabling is a daunting task to do. 2. Another option is fibre optics, which is latest in the field of networking. But laying and digging of fibre optics is quite expensive. 3. Radio modem is again an expensive technology that can transmit data without wires but lacks consistency because of technical reasons. HDSL (High-speed digital subscribe loop), a new technology, takes care of all these factors. This technology is accepted for efficacy and low cost. HDSL was developed in the early nineties at Bellcore, a research and development branch of the Regional Bell Operation Companies, USA. Based on this technology, a company, VXL Instruments Ltd, has launched SlipStream ES2000. It is an Ethernet bridge, which provides high-speed connectivity between two distant networks. It achieves a balanced transmission of data up to 1.168 MBPS over a single twisted pair copper wire. This product connects the existing network using standard RJ45 Ethernet.
