G.SHDSL Two-Wire Ethernet Network Extender
2. Overview
2.1 Introduction
The LR0201A-KIT, a G.SHDSL (Single-pair High-bit-rate Digital Subscriber Line) Two-Wire Ethernet Network Extender, provides
broadband full-duplex transmission with bandwidth up to 5.696 Mbps over a pair of copper twisted-pair lines for point-to-point
LAN connectivity between two Ethernet networks. The LR0201A-KIT is a cost-effective symmetrical broadband solution for band-
width-hungry applications such as LAN-to-LAN connectivity, Internet access, and VoIP applications over two twisted pairs.
Use the extenders for VoIP, Web hosting, or teleconferencing for more performance than you get with SDSL equipment. Distances
reach up to 7000 feet (about 2.1 km) at 5.606 Mbps, 10,000 feet (about 3 km) at 4.608 Mbps, or 22,500 feet (about 67.8 km)
at 192 kbps. Users can also select a fixed data rate for the copper line ranging from 64 kbps to 5.696 Mbps. Or, use the unit’s
rate-adaptive feature, which will choose the best data rate for your link from 192 kbps to 4.608 Mbps. The LR0201A-KIT also pro-
vides a console port for users to configure the settings and to monitor the connection status.
The LR0201A-KIT can be configured as either the central office (master) side or the remote (slave) side. LR0201A-KIT conforms to
the ITU-T Rec. G.991.2, to meet G.shdsl.bis network requirements.
2.2 Features
• ITU-T Rec. G.991.2 G.shdsl.bis compliance
• SHDSL trellis-coded pulse amplitude modulation (TCPAM) line code
• Fixed data-rate selection from 5.696 Mbps to 64 kbps for SHDSL line
• Adaptive data rate from 4.608 Mbps to 192 kbps for SHDSL line
• Maximum transmission distance: 22,500 feet (about 6.8 km) over 26 AWG twisted pair
• Noise margin
• 1 dB is guaranteed for fixed-rate and adaptive-rate modes
• STU-R (remote) will follow STU-C's (central office) for 192 kbps to 2.304 Mbps speed in fixed-rate mode
• RJ-48 connector for SHDSL line connection
• Two RJ-45 connectors for 10BASE-T/100BASE-TX Ethernet switch ports are autosensing and autonegotiating
• Ethernet Auto MDI-X for auto Tx/Rx swap so you don’t need a crossover cable
• Console port for network management configuration
• (7) LED status indicators
