2Challenges to Overcome Overcome Ethernet distance limitationMore bandwidth over Category 1/2/3support advanced media-rich applicationsDrive down per-line costs while driving up performance by utilizing Ethernet componentsRetain key QoS, security, provisioning and management featuresEnsure equipment is easy to use and provides platform for future applications
3Technology Solution: LRE (Ethernet Over VDSL) 5, 10 or 15 Mbps symmetric throughputMaps directly to full duplex EthernetAllows for true high speed BANsCo-exists with POTS and digital phonesRequires splitterUp to 5000 ft over single pair Cat 3Runs over Cat 1, 2 as well unstructured wiringBased on robust Catalyst switching platformVoice frequency bands can differ, so in addition to our own splitter we will be able to reference sell splitters for homologation requirements that don’t match our splitter. ISDN is an example of this. Our splitter will not work with ISDN although LRE is spectrally compatible.

12LRE Technology Overview Enables the use of Ethernet over existing, unconditioned, telephone-grade wireEnables Ethernet to coexist with “plain old telephone service” (POTS), Integrated Services Digital Network (ISDN) or private branch exchange (PBX) signaling servicesUses DSL coding and digital modulation techniques with EthernetProvides a point-to-point transmission that can deliver a symmetrical, full duplex, data rate of up to 15 MbpsLRE products are simple to install and interface with any existing Ethernet solutionLong range Ethernet (LRE), is an innovative technology that enables the use of Ethernet over existing, unconditioned, telephone-grade wire (copper twisted pair). The technology allows Ethernet LAN transmissions to coexist with either POTS (Plain Old Telephone Service), ISDN, or advanced PBX (Private Branch Exchange) signaling services over the same pair of ordinary copper wires. LRE technology uses the newest coding and digital modulation techniques from the DSL world in conjunction with Ethernet, the most popular LAN protocol.A LRE system provides a point-to-point transmission that can deliver a symmetrical, full duplex, raw data rate of Mbps over distances of up to 1 Mile (1.6 km). This easily provides a net 10 Mbps, in each direction. Products utilizing LRE technology are simple to install and interface easily with any existing Ethernet solution, to meet all present and future needs of enterprise managers, property managers, and consumers.
13LRE Technology—Bandwidth LRE technology can operate at up to 17 MbpsEnables transport of Ethernet data up to 15 MbpsTransport overhead does not reduce the Ethernet bandwidthLRE technology operates at a continuous raw symmetrical bi-directional data rate of 17 Mbps. This allows transport of Ethernet data up to 15 Mbps, in full duplex. The transport overhead does not reduce the Ethernet bandwidth and the system may thus be used totally transparently in an Ethernet network.

16Summary of LRE Key Technology Features Standard 10 Mbps Ethernet over regular twisted pair copper wireDistances of up to 4000 ft (1.2 km) at full-duplex 10 Mbps, 15 Mbps high-speed mode (3500 ft, 1 km)Simultaneous data and POTS, ISDN or PBX signaling services over the same lineUtilizes the most advanced multi-QAM modulation techniquesMinimum interference with other wire pairs and other servicesFull-duplex point-to-point transmissionLonger distances can be reached at lower ratesLow power-implementation, minimum heat-dissipation issuesSupports testing and management capabilitiesLRE technology was developed by Savan Communications to answer customers’ immediate needs for high-speed access. Development and implementation of LRE technology has been guided by the emerging VDSL standards. The telecom partners recommendations and their noise and interference models in the FSAN, the DAVIC, the ETSI and ANSI VDSL standards committees, and the QAM VDSL Coalition have been used in the design process.LRE offers standard Ethernet capabilities over existing telephone-grade wire coexisting simultaneously with POTS, ISDN, or advanced PBX signaling. LRE technology is the combination of the best from the two worlds of VDSL and Ethernet. It provides full duplex 10 Mbps 10BaseT Ethernet over the telephone-grade wire infrastructure, up to distances of 1 Mile (1.6 km). No other technology available in the market today can offer such high-speed transmission over copper lines to similar distances.LRE is the easiest, most cost effective solution for LAN connectivity and extension today.
