XL-12000B HIGH-SPEED NETWORK MODEM 1.0 XL-12000B Product Overview The XL-12000B modem is a high-speed, SDSL (Symmetrical Digital Subscriber Line) point-to-point modem created to extend Local Area Networks (LANs) up to 12,000 feet using ordinary telephone wires. 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.
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.
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.
XL-12000B HIGH-SPEED NETWORK MODEM 4.0 Installation 1. Remove the modem and wall transformer from the shipping carton. Remove the wall transformer from its box. Remove the plastic wrapper from around the modem. 2. Remove the cable ties from each of the cables and place them side by side. Each of the cables is identified as follows: (1) RJ-45 10Base-T straight-through cable: A cable with RJ-45 connectors is used to connect the modem to a 10Base-T hub or node.

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.
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.
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.
