Important safety instructions 8 The power source has to be adequately rated to assure safe operation of the equipment. The building installation and/or power source must provide overload protection. 9 Protective earth (PE) connection is essential to ensure safe operation before connecting to the power supply and telecommunication network. Do not defeat the purpose of the grounding-type plug by modifying the plug or using an adapter.
Important safety instructions 16 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 with the appropriate regulatory agencies and inspection authorities to ensure compliance. 17 A rare phenomenon can create a voltage potential between the earth grounds of two or more buildings.
Important safety instructions ! ! ! Warning: The battery can explode if incorrectly replaced. Replace the battery only with the same or equivalent type recommended by the manufacturer. Dispose of used batteries according to the manufacturer’s instructions. Avertissement: Il y a danger d'explosion si la batterie n'est pas remplacée correctement. Remplacer uniquement avec une batterie du même type ou d'un type recommandé par le fabricant.

The unit converts data to an SDSL format and sends it to the destination device.
DSLPipe DSU features DSLPipe DSU features The DSLPipe DSU includes the following features: • High-speed SDSL transport over a single copper twisted-pair telephone line • Symmetrical multirate data transmission from 144 Kbps to 2320 Kbps • Compatible and interoperable with major COE routers • Easy-to use • Low power consumption • Easy configuration • COE or CPE configuration • Transmission distance of almost 18,000 feet at 786 Kbps (with a 24 gauge wire) DSLPipe DSU configuration You can use
DSLPipe DSU architecture Figure 1-2 illustrates how you can use a DSLPipe DSU as COE. WAN V.35 Router A DSLPipe DSU (as COE) DSLPipe DSU (as CPE) V.35 Router B Figure 1-2. Example: Using a DSLPipe DSU as COE The DSLPipe DSU in Figure 1-2 accepts HDLC data from V.35 Router A. The unit converts the data into SDSL format and sends it, via a WAN link, to another DSLPipe DSU that is configured as CPE. That unit then sends the data to V.35 Router B.

Setting up the DSLPipe DSU 1 2 3 5 4 Figure 2-1. Package contents Setting up the DSLPipe DSU Figure 2-2 shows the DSLPipe DSU’s rear panel. To set up your DSLPipe DSU, you use components located on the rear panel to set the data transmission rate, configure the unit as either CPE or COE, and connect the necessary cables Figure 2-2. DSLPipe DSU Rear Panel DC IN 2-2 RATE V.
Setting up the DSLPipe DSU Setting the data transmission rate To set the DSLPipe DSU data transmission rate, use a pen to move the DIP switches.Table 2-1 shows the DIP switch settings for each rate. Move the DIP switch down to turn the switch on. Move a switch up to turn it off. Table 2-1.
Connecting the cables Table 2-2 shows the proper setting for each configuration . Table 2-2. CPE vs. COE configuration Configuration DIP Switch 4 CPE OFF COE ON Connecting the cables To connect your DSLPipe DSU: 1 Use the V.35 to DB-25 cable to connect the V.35 device to the DSLPipe DSU. 2 Use the WAN cable to connect the DSLPipe DSU to the SDSL line. 3 Use the power supply cable to connect the DSLPipe DSU to a power source. Plugging the power supply automatically turns on the DSLPipe DSU.

Connecting serial cable and setting up communications software 2 Use a communications program (such as HyperTerm, PROCOMM PLUS, Zterm, or any other program that supports VT100 terminal emulation) to open a session directly with the port to which the DSLPipe unit is connected. 3 Set your communications software to connect with the following settings: Note: If you are not already familiar with the settings listed, see the documentation for your communications software.
Viewing configuration information Press any key on the keyboard and the DSLPipe unit’s configuration menu appears: SDSL V.35 DSU Software Version 3.31 0. Show DSL Status 1. Change Configuration 2. Upgrade Operation Software 3. Upgrade SDSL Firmware 4. Debug Mode Figure 3-1. DSLPipe configuration window Note: At this time, you cannot change DSLPipe configuration, upgrade the DSLPipe software, or upgrade the DSLPipe firmware using the on-board software.
Viewing configuration information Table 3-1. Fields in the DSLPipe status window (Continued) Fields Description V35 Indicates OFF_line or ON_line Data Bit Polarity Indicates Norm (Normal) or Rev (Reverse). The default is Rev.This means that the transmitter inverts the data polarity before sending data. Sign/Magn Bit Seq Indicates Norm (Normal) or Rev (Reverse). The default is Rev. This means that the magnitude bit is followed by the sign bit. Noise Margin Shows the noise margin value (in dB).
Viewing diagnostic information Table 3-1. Fields in the DSLPipe status window (Continued) Fields Description V.35 ch Tx CRC Shows either Enable or Disable. The default is Enable. This means that the CRC is appended to the end of the frame when data is sent over the V.35 line. V.35 ch RxC Polarity Indicates Norm (Normal) or Rev (Reverse). The default is Norm.This means that data will be sampled at the rising edge of the clock. V.35 ch TxC Polarity Indicates Norm (Normal) or Rev (Reverse).
