Important safety instructions

A. GENERAL
1 Read and follow all warning notices and instructions marked on the product or

included in the manual.

2 There are no operator serviceable parts within the unit. Refer all servicing to

trained service personnel.

3 Product installation should be performed by trained service personnel only.
4 Install only in restricted-access areas in accordance with UL1950, C22.2 No. 950,

and IEC60950

5 The maximum recommended operating ambient is 104° F (40° C). Allow

sufficient air circulation or space between units when installed in a closed or
multiple-rack assembly.

6 Slots and openings in the cabinet are provided for ventilation. To ensure reliable

operation of the product and to protect it from overheating, these slots and
openings must not be blocked or covered. Installation without sufficient airflow
can be unsafe.

7 Equipment mounted in a rack should b e distributed to prevent a possible

hazardous condition due to uneven loading. The rack should safely support the
combined weight of all equipment. This product weighs XX lb. (XX kg).

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.

Important safety instructions

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.
