IEX-402-SHDSL Series Quick Configuration Guide First Edition, January 2013

1. Product Overview The IEX-402-SHDSL series is an entry-level managed DSL Ethernet extender that allows you to extend point-to-point Ethernet connections over a SHDSL link in a cost-effective way. Depending on cable quality, environmental noise, and connection distance, the IEX-402-SHDSL series offers a maximum data rate of up to 15.3Mbps and a transmission distance of up to 8 km. The following configuration steps will allow you to effectively reduce deployment time, simplify maintenance, and enhance manageability. 2. Configuration and Setup 2.1 Wiring the devices The IEX-402-SHDSL series must work in pairs. The upper port is a 10/100BaseT(x) port to connect to Ethernet-enabled device, such as a switch or a PLC. The lower port is designed to connect both DSL extenders via a 2-wire twisted copper cable. NOTE Device boot-up to connection-ready time: 70 seconds to 4 minutes, depending on line conditions. NOTE The DSL port is designed to be used on private communication lines for point-to-point connections only, and is not able to be connected to Public Switched Telephone Networks (PSTN). 2.2 Configuration Option 1: Auto mode/plug-and-play Every IEX-402-SHDSL extender is configured (via DIP switch) as a CO device by default. When connected, each pair will automatically designate one device as the CO and the other device as the CPE through Auto CO/CPE negotiation, which will attempt to establish the maximum data rate based on the line conditions and distance. NOTE Auto CO/CPE negotiation is only valid under STD mode. NOTE Depending on line conditions, Auto CO/CPE negotiation will take approximately 20 seconds to 3 minutes longer to establish a connection, when compared to a manually configured (CO to CPE via DIP switch settings) connection. - 2 -

Option 2: Manual mode 2.2.1 Hardware configuration The IEX-402-SHDSL provides four DIP switches for advanced configuration. DIP switch 1: CO/CPE assignment Manually set the device as a CO or CPE. DIP switch 2: DSL speed/snr display Decide whether connection speed or SNR (signal-to-noise ratio) status will be displayed on the LED indicator. DIP switch 3: ANNEX A/B setting Check the cable type being used between the extenders. If the cable is US-type/0.5mm, please configure as ANNEX A. Otherwise, please set to default ANNEX B. DIP switch 4: DSL link speed STD mode supports data rates of 192 kbps to 5696 kbps. TURBO mode supports data rates of up to 15.3Mbps (500 meters). If Turbo mode is enabled, the extenders will step through different speeds until the best bit-rate is determined based on existing line conditions. NOTE Link speed setting of DIP switch 4 must be identical on both extenders. Restart both extenders if DIP switch 4 has been reconfigured. - 3 -

2.2.2 Software configuration Step 1: Set DSL port speed Select the desired transmission speed and the extender will try to attain that speed. If line condition degrades (reduced SNR), but the device is still able to keep the link, the DSL SNR/SPEED LED indicator will display a reduced SNR. However, if the line condition is too poor to maintain the link, the connection will be very unstable and/or disabled, changing to Auto speed, or to a lower transmission speed until the link is able to connect, is suggested. NOTE Speed settings are only available in STD mode. Step 2: Enable/Disable Link Fault Pass-Through. By enabling the Link Fault Pass-Through (LFP) function, when an Ethernet or DSL port connection fails, the Ethernet connection will be disabled on both DSL extenders to prevent packet transmission across the failed path. NOTE Please make sure that all ports are well-connected while enabling the Link Fault Pass-Through (LFP) function. Otherwise, both Ethernet connections will be disabled and you will not be able to connect to the configuration interface. - 4 -

3. Performance The IEX-402-SHDSL series is the ideal solution to extend point-to-point Ethernet connections over 2-wire copper cables. Depending on the line conditions, short-range connections normally can provide high data transmission rates of up to 15.3 Mbps (500 m) on both upstream and downstream links, and provide a maximum transmission distance of up to 8 km. The table below shows the performance test results under a noise-free environment. 4. Quick Diagnostics and Easy Management The IEX-402-SHDSL series provides LED indicators and management functionalities for quick troubleshooting. Option 1: LED Indicators for On-site Troubleshooting During initial installation, if the line quality is acceptable, the connected pairs will perform CO/CPE detection before negotiating the connection speed over the SHDSL link. The CO/CPE LED color will switch between amber and green until both extenders have finalized CO/CPE detection. Then both extenders will determine the best transmission rate. If the link is unable to be established within 8 minutes, you may need to check the segment for problems such as a loose connection, environmental noise, or excessive distance. - 5 -

After both extenders have negotiated the best transmission rate, the DSL SPEED/SNR LEDs will indicate the connection quality of the SHDSL link. Fewer bars on the LEDs indicate poor SNR or lower speed. The extenders will maintain the best transmission quality and speed possible under the given environment. When no bars are showing on the DSL SPEED/SNR LEDs, communication is unable to be established. The "STATE" LEDs indicate the location of the link failure, allowing network operators to immediately determine the location and quickly recover from a link failure - 6 -

Option 2: Virtualization Panel and Management via NMS for Easy Remote Management The virtual panel in the web-based browser provides easy remote management at a glance, and the SNMP protocol support allows the IEX-402-SHDSL series to be managed by Moxa s MXview network management software for total network manageability.
