5 Overview The SDTU-01 SDSL DSU with V.35 interface is a data access DSU modem with the latest multi-rate SDSL (Symmetrical Digital Subscriber Line) technology offering both long range and high speed data transmission with rates from 144Kbps up to 2320Kbps. The transmitting data rate may be adapted for the best "rate vs. range" performance for efficient and stable data transmission. The SDTU-01 uses the 2B1Q line code with echo cancellation to transmit its high data rate over a single twisted pair of telephone wire without being affected by bridge taps or mixed cable links. It also provides high immunity to background noise and enables transmission over multiple pair cables. 3

11 Important Safety Instructions The following safety instructions apply to the SDTU-01: 1. Be sure to read and follow all warning notices and instructions. 2. The maximum recommended ambient temperature for SDTU-01 is 40(104) Care must be taken to allow sufficient air circulation or space between units when the SDTU-01 is installed inside a closed rack assembly. The operating ambient temperature of the rack environment might be greater than room temperature. 3. Installation in a rack without sufficient air flow can be unsafe. 4. Racks should safely support the combined weight of all equipment. 5. The connections and equipment that supply power to the SDTU-01 should be capable of operating safely with the maximum power requirements of the SDTU-01. In the event of a power overload, the supply circuits and supply wiring should not become hazardous. The input rating of the SDTU-01 is printed on the nameplate. 6. The AC adapter must plug in to the right supply voltage, i.e. 120VAC adapter for North America and 230VAC adapter for Europe. Be sure the supplied AC voltage is correct and stable. If the input AC voltage is over 10% lower than the standard may cause to malfunction of the SDTU-01 unit. 7. Installation in restricted access areas must comply with Articles , , and of the national Electrical Code, ANSI/NFPA Do not allow anything to rest on the power cord of the AC adapter, and do not locate the product where anyone will walk on the power cord. 9. Do not service the product by yourself. Opening or removing covers can expose you to dangerous high voltage points or other risks. Refer all servicing to qualified service personnel. 10. General when installed in the final configuration, the product must comply with the applicable safety standards and regulatory requirements of the country in which it is installed. If necessary, consult the appropriate regulatory agencies and inspection authorities to ensure compliance. 9

12 11. A rare condition can create a voltage potential between the earth grounds of two or more buildings. If products installed in separate building are interconnected, the voltage potential can cause a hazardous condition. Consult a qualified electrical consultant to determine whether or not this phenomenon exists and, if necessary, implement corrective action before interconnecting the products. If the equipment is to be used with telecommunications circuit, take the following precautions: Never install telephone wiring during a lightning storm. Never install telephone jacks in wet location unless the jack is specially designed for wet location. Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface. Use caution when installing or modifying telephone lines (other than a cordless telephone) during an electrical storm. There is a remote risk of electric shock from lightning. Do not use a telephone or other equipment connected to telephone lines to report a gas leak in the vicinity of the leak. 10

Connect the local loop (twisted copper pair telephone wire) to the WAN port (SDSL, RJ-11) by using the RJ-11 cable attached. Be sure this local loop had been properly connected to the Central Office side SDSL equipment. 2. Connect the DB-25 connector marked "V.35" with "DB-25 to V.35" cable to the router. To correctly connect with the router cable. Please refer to the section of "Cables" for detail pin assignment. The other end of router will connect to LAN (Local Area Network) or other data equipment. Router 3. Power connection -- Warning : Do not apply the AC power before all the connections above have been connected. Plug in the AC Adapter to the wall AC socket Connect the DC jack to the DC-IN of the unit 11

Use the RS-232 serial cable to connect to a ASCII data terminal. The TERMINAL is VT-100 compatible. A PC with data terminal emulation software installed, can be connected via serial COM port in data terminal mode. RS232 12

15 Hardware Setup DSL rate and terminal type can be set up by adjusting the 4-pole DIP switch on the rear panel. Sw. 1 to Sw. 3 are for adjusting the DSL rate while Sw. 4 is for termination type.

16 Point-to-point Operation 1. The SDTU-01 should be located on each side of the connection. One side must be set to "CO" and the other side must be set to "RT". Refer to the section on "Hardware Setup" for the CO & RT setup. 2. Insure that both CO & RT SDTU-01s are set to the same DSL rate. For example, 784Kbps. 3. Make sure that both CO & RT SDTU-01s have been connected to the Routers properly. 4. Check the WAN LED on the SDTU it will remain lit when the Link is successfully established. The DSL training process may take around one minute and the WAN LED will flash during the training process. 5. After the DSL link is established, check the router setup. Both CO & RT side routers must be set to use the same Link Protocol, i.e. PPP or Frame Relay link. Both side routers must also set the same parameters. Otherwise, they may fail to communicate with each other even though the DSL link is ready. 6. Follow the Router manual to set the IP and other parameters. When the router is properly set, you are ready to use the high-speed connection between the two networks. You may test the data transportation speed by using the "Ping" command or FTP file transfer. 14
