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 telecommuni cation network. Do not defeat
the purpose of the grounding-type plug by modifying the plug or using an
adapter. Use an outlet tester or a voltmeter to check the ac receptacle for the
presence of earth ground. If the receptacle is not properly grounded, the
installation must not procede until a qualified electrician has corrected th e
problem.
If the power supply is fed from a power source with no protective-earthing path
(such as in certain Nordic countries), connect an earth-grounded copper wire to
the dedicated wiring terminal marked with (PE symbol) on the chassis. The
minimum size of the wire for a DSLPipe V.35 unit with rated input current not
exceeding 6A is AWG 18 and cross-sectional area 0.75 mm
Models with ac power inputs are intended for use with a single-phase three-wire
power cord (which includes earthing conductor).
For models with dc power inputs, the protective earth connection must be
established by using the dedicated earthing terminal marked with the PE symbol
or, if provided, the earthing pin of the input terminal block.
10 Models with dc power inputs must be connected to a -48V dc supply source that
is electrically isolated from the ac source in accordance with UL1950, C22.2 No.
950, and IEC60950.
11 For products installed in Nordic countries (except Central Office equipment), a
type B plug or permanent connection must be used for connections to the main
power supply.
12 Before installing wires to the dc power terminal block, verify that these wires are
not connected to any power source. Installing live wires (that is, wires connected
to a power source) is hazardous.
13 Do not allow anything to rest on the power cord, and do not locate the product
where people will walk on the power cord.
14 Do not attempt to service this product yourself. Opening or removing covers can
expose you to dang erou s h i gh vol t age points or other risks. Refer all se rvi c ing to
qualified service personnel.
15 General purpose cables are provided with this product. Special cables, which
might be required by the regulatory in spection authority for the installation site,
are the responsibility of the customer.

16 When installed in the final confi gur ation, 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 gr ounds of
two or more buildings. If products installed in separate buildin gs are
interconnected, the voltage potential might cause a hazardous condition. Consult
a qualified electrical consultant to determine whether or not this phenomenon
exists.
In addition, if the equipment is to be used with telecommunications circuits, take the
following precautions:
• Never install telephone wiring during a lightning storm .
• Never install telephone jacks in wet locations unless the jack is specifically
designed for wet locations.
• Never touch uninsulated telephone wires or terminals unless the telephone line
has been disconnected at the network interface.
• Use caution when installing or modifying telepho ne lines.
• Avoid using equipment connected to 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.

The DSLPipe DSU (SDSL) is a modem that allows you to send data across two
dissimilar devices. The unit converts data to an SDSL format and sends it to the
destination device.You can use the unit for high-speed symmetrical data
transmission (from 1 44 Kbp s to 232 0 Kbps ) on a si ng l e copp er t w ist ed-pair wire.
Note: You cannot use a DSLPipe DSU for channelized services such as voice
transmission.
The DSLPipe DSU uses 2B1Q line encoding with echo cancellation to transfer at
a high data rate. It also prov id es hi g h immunity to background noise. The size of
the wire, in part, determines the maximum transmission rate and distance, as
shown in Table 1-1.

Before you can view the configuration information for the DSLPipe unit, you
must set up VT100 emulation to view the on-board software.
Items you need
• You need a serial cable that can plug into an available, enabled serial port on
your computer . The othe r end of t he cable must ha ve a male DB-9 connect or
to fit the serial port connector on the back of the DSLPipe unit. If your
computer is a Macintosh, the cable must fit the modem port’s nine-pin mini
DIN connector.
• You also need communications software that supports VT100 emulation.

Connecting serial cable and setting up communications software
To establish a serial connection, proceed as follows:
1 Use a serial cable to connect your computer’s serial (or modem) port to the
terminal port on the back of the DSLPipe unit.
DSLPipe DSU (SDSL) User’s Guide 3-1
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. If you’re using the
software for the first time, going through an online or printed tutorial (if the
software includes one) is a good way to get started.
– Direct connection: Tell the software that there is a serial cable
connecting the DSLPipe directly to the computer.
– Serial port: Specify which of the computer’s serial ports the software
uses. If the only serial port available is currently used by an internal
modem, you may need to use your computer’ s setup soft ware to specify
an external connector for the port that will be used in place of the
internal modem. In some cases, you also may need to remove the
modem. See the manual for the modem and your computer’s user
manual for details.
– Terminal type: Specify VT100.
– Duplex: If the software lets you choose, specify Full. Because this is by
far the most common choice, most communications software sets this
by default.
– Bits per second: Specify 57600.
– Data bits: Specify 8.
– Parity: Specify None.
– Stop bits: Specify 1.
– Flow control: Turn off software flow control (XON/XOFF) and, if
possible, hardware flow control (RTS/CTS). Specify None.
