G.SHDSL Four-Wire Ethernet Network Extender Kit
2. Overview
2.1 Introduction
The LR0202A-KIT, a G.SHDSL (Single-pair High-bit-rate Digital Subscriber Line) Ethernet Network Extender, provides broadband
full-duplex transmission with bandwidth aggregation up to 10.8 Mbps over two pairs of copper line for point-to-point LAN con-
nectivity between two Ethernet networks. This is enough speed to support VoIP, Web hosting, and teleconferencing. The kit
includes two extenders. The LR0202A-KIT can be configured into either STU-C for the central (master) side or STU-R for the
remote (slave) side. The LR0202A-KIT conforms to the ITU-T Rec. G.991.2, to meet G.shdsl.bis network requirements. It offers a
cost-effective symmetrical broadband solution for bandwidth-hungry applications such as LAN-to-LAN connectivity, Internet
access, and VoIP applications over two twisted pairs.
Over one pair of 26 AWG (0.5 mm) copper twisted-pair wire, the LR0202A-KIT sends data up to 12,000 feet (2.3 miles, about
|3.7 km) at 2.304 Mbps and 4500 feet (about 0.8 miles, 1.3 km) at the maximum rate of 10.8 Mbps. It can also reach 5500 feet
(1 mile, 1.6 km) at 9.216 Mbps over two pairs of 26 AWG (0.5 mm) copper twisted-pair wire, and go 22,500 feet (about 6.8 km)
at 192 kbps. With its rate-adaptive features, the LR0202A-KIT may provide even longer transmission distances. Users can also
select a fixed data rate for the copper line ranging from 64 kbps to 5.696 Mbps over one pair or 128 kbps to 10.8 Mbps over two
pairs. The LR0202A-KIT provides a console port for the user to configure the settings and to monitor the connection status.
Table 2-1 lists the extenders’ low-speed and maximum-speed fixed data rates and adaptive data rates.

Chapter 3: Installation
3. Installation
1. Connect the SHDSL line to the DSL RJ-48 connector on the LR0202A-KIT rear panel.
Pins 4 and 5 for SHDSL line Loop 1
Pins 1 and 2 for SHDSL line Loop 2
Figure 3-1. RJ-48 connector, Pins 4 and 5 and Pins 1 and 2.
2. Connect the Ethernet interface to the RJ-45 Port with the included CAT5 cable.
3. Connect the included power cord to the AC outlet.
CAUTION: Verify that the AC-DC adapter conforms to your country’s AC power requirement and then insert the power plug.
NOTE: The Interconnecting cables should be rated for external use and for the application’s voltage, current, anticipated tem-
perature, flammability, and mechanical serviceability.
4. Turn on the power switch. Set one G.SHDSL Four-Wire Ethernet Network Extender as the CO site (master) from the console
port and the other as the REMOTE (slave) site.
5. Set the desired data rate for SHDSL connection from the console port.
NOTE: Set both G.SHDSL Four-Wire Ethernet Network Extenders the same.
6. Both G.SHDSL Four-Wire Ethernet Network Extenders will automatically connect with each other.
NOTE: Turn on the power switch, and the LR0202A-KIT will then run self-test routines. There will be two or more handshaking
cycles when adaptive rate is selected. The system will automatically adapt to the maximum rate according to the loop
distances. The maximum adaptive rate is 4.608 Mbps for 1-pair mode and 9.216 Mbps for 2-pair mode. The maximum
fixed data rate is 10.8 Mbps.

4. Console Configuration
The LR0202A-KIT provides an RS-232C console port for user to monitor the OA&M status through a VT100 terminal. This section
covers the operating procedures and settings for all screen selections.
Connect the RS-232 cable to the computer’s COM port as shown in Figure 4-1. Set the personal computer to VT100 or VT102
type through HyperTerminal. Press the <ESCAPE> key and the main menu will be shown on the terminal’s screen. The terminal
operations can then start.
If you press the <ESCAPE> key and the screen of the terminal does not display, the COM port might be set incorrectly. Choose
the correct COM port (COM1 or COM2) on the computer, and press the <ESCAPE> key again to make sure that the main menu
appears on the terminal screen.
NOTE: Set the COM port should be set as 9600 bps, 8 data bits, 1 stop bit, no parity, and no flow control.

CO/RT:
CO/RT has 2 options: STU-C and STU-R. To establish a successful connection for two G.SHDSL Two-Wire Ethernet Network
Extenders, set one unit to STU-C (CO Site) and the other unit to STU-R (Remote Site).
2P/1P:
2P/1P has 2 options: 1 Pair and 2 Pairs. LR0202A-KIT supports both 1-pair and 2-pair SHDSL applications. To establish a successful
connection for LR0202A-KIT, set the two units to the same selection.
4.2.2. DSL Speed Screen
From the DSL Speed screen, users can configure DSL transmission rates.
For 1-pair setting in the DSL Mode menu, the options are:
64 kbps, 128 kbps, 192 kbps, 256 kbps, 384 kbps, 512 kbps, 768 kbps, 1152 kbps, 1536 kbps, 1544 kbps, 2048 kbps,
2304 kbps, 3072 kbps, 4608 kbps, 5696 kbps, and adaptive speed.
For 2-pair setting in the DSL Mode menu, the options are:
284 kbps, 512 kbps, 768 kbps, 1152 kbps, 1544 kbps, 2304 kbps, 3072 kbps, 3088 kbps, 4096 kbps, 4608 kbps,
6176 kbps, 9216 kbps, 10.8 Mbps, and adaptive speed.
The user must set both extenders to the same speed selection to establish a successful connection for 64 kbps, 128 kbps, 3072
kbps, 4608 kbps, 5696 kbps, and adaptive speed.
For the rate speed options between 192 kbps and 2.304 Mbps, the remote (slave) site will follow the CO (master) site’s speed,
regardless of the speed selected for the remote site unit.
When setting for adaptive rate, two or more activation cycles are necessary. The system will automatically adapt to maximum
