The modem uses Digital Subscriber Line (DSL) transmission technology to deliver data at 2 Mbps. The XL-12000B is designed for easy installation. Front panel LEDs provide status and operational information. The modem is ideally suited for connecting LANs in a campus environment where LANs may be spread out over two miles. The XL-12000B units function as a pair; one as Master and the other as Slave. The XL-12000B will function as a bridge using Spanning Tree Protocol (STP) connecting two independent segments. This mode allows the modem to pass both IP and non-IP packets transparently making the segments a single network. Examples of non-IP packets include Novell’s IPXTM and Apple’s AppleTalkTM. 1.0 XL-12000B PRODUCT OVERVIEW TUT SYSTEMS 1 XL-12000B HIGH-SPEED NETWORK MODEM 2.0 2 Technical Specifications Data Rate: 2.048 Mbps Line Length: Up to 12,000 ft. on 24 AWG wire Up to 9,000 ft. on 26 AWG wire Ethernet Interface: Compliant with IEEE 802.3 10Base-T Operating Voltage: 120/240 VAC 50/60 Hz wall transformer Power Consumption: 5 Watts Operating Temperature: -5˚ to 55˚ C Storage Temperature: -40˚ to +70˚ C Relative Humidity: 5% to 90% (non-condensing) Compliance: UL, CSA, CE, FCC Part 15 Class A Software: Spanning Tree Protocol (STP) Bridging (rfc-1493) TUT SYSTEMS 2.0 XL-12000B TECHNICAL SPECIFICATIONS XL-12000B HIGH-SPEED NETWORK MODEM 3.0 What’s in the Box Confirm that there is one each of the following items: Description • XL-12000B Modem • XL-12000B User Guide • RJ-45 10Base-T Straight-through Cable • RJ-11 DSL Line Cable • Wall Transformer w/ Lightning Protection 3.0 WHAT’S IN THE BOX TUT SYSTEMS 3 XL-12000B HIGH-SPEED NETWORK MODEM 4.0 Installation 1.

Power LED The blue Power LED remains lit while the unit has power. Activity LEDs The DSL RX and DSL TX LEDs flash green when receiving and transmitting data. Status LED At power up, the Status LED flashes red while the modem performs a diagnostic self-test and performs software decompression. After the modem completes its self-test, the LED will extinguish, indicating that the modem is ready for normal operations. Steady red indicates one of two conditions: 1) the link is lost and the modems are trying to establish a link or 2) there is a unit failure. DSL Link A flashing DSL link LED indicates that the modem is in the process of linking to the other modem. After the two XL-12000B units have secured the DSL link, the DSL Link LED glows a steady green. The LED is off when there is no link. Master/Slave Switch One XL-12000B serves as the Master unit and the other serves as Slave. It does not matter which unit of the pair is set to “Master” and which is set to “Slave”, but the pair must have opposite settings. Changing this switch does not require the user to reboot the modems. 5.0 PANEL INDICATORS AND CONNECTORS TUT SYSTEMS 7 XL-12000B HIGH-SPEED NETWORK MODEM Figure 5.1 XL-12000B Front Panel DSL RX Flashing Green: On when receiving data.

TUT SYSTEMS 9 XL-12000B HIGH-SPEED NETWORK MODEM 6.0 10 Power and Boot Up Sequence 1. Verify that the LAN and DSL lines are connected according to the wiring diagram described in the “Installation” section (see Figure 4.3. 2. Plug the 120 VAC/12 VDC wall transformer (220VAC for international use) into a wall outlet. Verify that the Power (blue) LED comes on. 3. Verify that the 10Base-T Link (green) LED on the rear panel is illuminated. If the unit is not connected to an Ethernet (10Base-T) source (e.g., computer), this LED will illuminate momentarily on power-up and then extinguish. When properly connected, the 10Base-T Link LED will be lit continuously. 4. Immediately upon power-up, the modem will begin its boot-up routine. The Status LED flashes red as the modem cycles through its initialization process. After initialization the DSL link light will blink and the Status light will remain red. If the DSL link light does not blink, refer to the “Troubleshooting” section. If the link time takes longer than one minute, refer to the “Troubleshooting” section. 5. The modem is now ready for operation. TUT SYSTEMS 6.0 POWER AND BOOT UP SEQUENCE XL-12000B HIGH-SPEED NETWORK MODEM 7.0 Troubleshooting This section is designed to assist in troubleshooting the XL-12000B. It also describes how to reach Technical Support at Tut Systems. Tut Systems takes pride in its products and would be more than happy to help with problems associated with the XL-12000B. Please take a moment and review the following answers to commonly asked questions before calling Technical Support. 1. The blue Power LED remains off. Verify that the wall transformer is plugged into an electrical outlet and that the connection to the modem is secure. Confirm the modem is plugged into a “live” electrical outlet. Make sure no light switch controls the plug and has been inadvertently turned off. It is not a recommended configuration to have the modem plugged into an electrical outlet that is controlled by a light switch. 2. The Status LED continues to stay red and the DSL link LED is not blinking. Try power cycling the modem by unplugging the modem and plugging it back in. If after power cycling the Status LED remains red, contact Customer Support. 3. The DSL Link LED never starts blinking. The DSL line is not plugged in or the DSL line is not properly connected to the “remote” end. Verify that the cable is properly connected at both ends. Both modems have the same setting on the Master/Slave switch. Verify by checking both modems’ Master/Slave switch on the front panel. Make sure that one of the modems is a Master and the other is a Slave. Check all patch cables to be sure the pinout is correct and connections are well seated. 7.0 TROUBLESHOOTING TUT SYSTEMS 11 XL-12000B HIGH-SPEED NETWORK MODEM 4. The DSL Link LED blinks for a long time. Blinking for a long time can indicate failure to communicate with the other modem within the acceptable noise parameters or that the distance between modems exceeds 12,000 feet. Verify the length of the DSL line and ensure it meets the length limits described in Appendix B. If it meets the limits, then have the line tested for defects. Another reason for continuous blinking is that both modems are either Masters or Slaves. Verify by checking both modem’s Master/Slave switch on the front panel. Make sure that one of the modems is a Master and the other is a Slave. A Master modem will send out a pulse on the wire to try and communicate with a Slave modem. 5. The 10Base-T LED never illuminates. If connecting to a hub, make sure the Ethernet connection switch on the back of the modem is set to “Normal”. Check the hub to see that its link light is illuminated. If the light is still not illuminated, try a different straight-through cable. If connecting to a PC, server, or workstation, make sure the Ethernet connection switch on the back of the modem is set to “Crossed”. Verify that the link light is illuminated on the PC. If the 10Base-T cable being used was not the cable provided, make sure it adheres to the pinout assignments for 10Base-T (see Appendix A). 12 TUT SYSTEMS 7.0 TROUBLESHOOTING XL-12000B HIGH-SPEED NETWORK MODEM 8.0 Technical Assistance and Customer Support Maintenance and Repair Tut Systems offers a comprehensive range of customer support services, including technical assistance, installation, and maintenance agreements.

Use a cable scanner or an ohmmeter to measure the lengths of phone wire that will connect the modems. When using an ohmmeter, short-circuit one end of the phone wire and measure the resistance between the two wires at the other end . Figure B.1 Using an Ohmmeter to Measure the Length of Phone Wire 600 Ohmmeter Short Pair Together OHMS Punchdown Block 2. Punchdown Block Multiply the resistance by 20 to find the length of the wire in feet. For example, 600 ohms would indicate a cable length of about 12,000 feet: 600 x 20 = 12,000 (+/-). This formula works for 24-gauge phone wire.
