OVERVIEW
This guide contains installation information for the ADC WorldDSL™RS
UTU-701C List 1 and ETU-751C List 1 Rate Selectable HDSL line and
desktop units.
RATE SELECTABLE HDSL
WorldDSL RS (rate selectable) is a single pair High-bit-rate Digital
Subscriber Line (HDSL) solution that offers extended reach capabilities
through the use of industry-leading multi-rate DSL technology. The
UTU-701C and ETU-751C deploy HDSL in networks using a single pair of
copper wires running at speeds between 256 kbps and 2048 kbps. The HDSL
payload rates are menu selected in time slot increments of 64 kbps, ranging
from 64 kbps to 2048 kbps. Transmission ranges vary according to the rate
selected. Depending on noise environment, ranges of up to 7.1 km (4.4 miles)
are possible at the lowest-selectable HDSL payload rates (256 kbps), using
0.51 mm wire. Longer ranges are possible with larger wire.
UTU-701C LINE UNIT
The UTU-701C can be configured as a Line Termination Unit (LTU) or
Network Termination Unit (NTU). The default configuration is NTU.
When configured as an LTU, the UTU-701C serves as the Exchange Office
side of a repeaterless, HDSL transmission system. The LTU-configured unit
connects to an NTU-configured unit (UTU-701C or ETU-751C) over one
twisted-pair of copper wires, completing the HDSL transmission system.
Use of this product in a manner other than defined in this
installation guide may cause damage to equipment or injury
to personnel.
Falls der Gebrauch von diesem Produkt nicht gemaess der
Definition im Installations Handbuch eingehalten wird,
besteht die Gefahr, dass Schaden am Geraet oder sogar
Koerperverletzungen entstehen koennten.
WorldDSL RS units are not backward compatible with
standard HDSL or management unit firmware. The installed
firmware must be that designed for rate selectable units.

Overview 700-701-900-02, Revision 02
2 June 5, 2002 UTU-701C and ETU-751C List 1
The UTU-701C accepts the DTE payload at its G.703 port and transports the
data to the remote unit at the selected HDSL rate. The UTU-701C requires
-36 to -72 Vdc from a local power supply or an enclosure’s AC-to-DC power
supply; it does not supply power to other HDSL units.
ETU-751C DESKTOP UNIT
The ETU-751C is housed in a plastic enclosure with interface and power
connectors for use as an integrated desktop unit. All functions of the
ETU-751C, with exception of power requirements, are identical to the
UTU-701C. The ETU-751C requires a source of 100 to 240 Vac at
50 or 60 Hz.
TRANSMISSION RANGES
Transmission ranges assume the presence of noise according to the ETSI
model described in TS 101 135. The expected Bit Error Rate (BER) under this
model is 1x10-7. The transmission ranges in such a noise environment at the
various HDSL payload rates over one twisted-pair of 0.4 mm and 0.51 mm
copper wire are listed below.

256 kbps (see “HDSL Payload Rates” on page 18).
(b) The maximum no-noise transmission range is approximately 7.1 km
(4.4 miles).

INSTALLATION
This section contains instructions for installation of the UTU-701C line unit
and the ETU-751C desktop unit.
INSPECTION
Before installing the line or desktop unit, inspect it for signs of damage. If the
unit has been damaged in transit, immediately report the extent of the damage
to the transportation company and to ADC DSL Systems, Inc.
SAFETY
To ensure your safety when servicing and installing this equipment, please
take the following precautions:
Input voltage for the UTU-701C line unit (nominal -48 Vdc,
tolerance -36 to -72 Vdc) must be supplied by an isolated DC
source that complies with TNV or earthed SELV require-
ments of the latest version of IEC 950.
Be careful when installing or modifying telephone lines.
Dangerous voltages can be present. It is unsafe to install
telephone wiring during a lightning storm.
Always disconnect all telephone lines and power connections
before servicing or disassembling this equipment. All wiring
external to the product should follow the local wiring codes.
Die Eingangsspannung fuer die UTU-701C Karte is nominell
–48 VDC, Toleranz -36 bis –72 VDC. Die Gleichstromquelle
muss den Vorschriften gemäß der Norm EN60950 fuer
Fernsprechnetzspannung (TNV) und
Sicherheitskleinspannung (SELV) entsprechen.
Walte Vorsicht beim Installieren oder Ändern von
Telefonlinien. Gefährliche Spannungen könnten anliegen.
Es ist nicht sicher während eines Gewitters Telefondräte zu
installieren.
Bevor Wartung oder Auseinandernehmen des Gerätes
müssen immer alle Telefon- und Netzkabel ausgezogen
werden. Alle externen Verdrahtungsarbeiten sollten nach den
hiesigen Elektrizitätsvorschriften ausgeführt werden.

LINE AND DESKTOP UNIT INSTALLATION
This section describes the jumper and cable connections required when
installing the UTU-701C line unit and the ETU-751C desktop unit.
Jumper Settings
Jumpers must be set if using a 120Ωinterface or if grounding your G.703
cables at the data port. The locations of these jumpers (P8, P11, and P12) are
illustrated below.
Line and Desktop Unit Jumper Settings
To set the jumpers on the line or desktop unit:
1If installing a desktop unit, remove the four screws on the bottom of the
unit and set aside the top cover.
Wear an antistatic wrist band connected to earth ground
when installing these units. Avoid unnecessary contact with
board-mounted components.

2In compliance with the ITU G.703, jumper P8 allows connection of the
outer conductor of the coaxial pair, or the screen of the symmetrical pair,
to earth (frame ground) at the G.703 input data port. Do one of the
following:
•Do not install a jumper. This is the factory setting and provides the
standard G.703 input port interface.
•Short pins 1 and 2 of P8 for the 120Ωinput.
•Short pins 2 and 3 of P8 for the 75Ωinput.
3Jumpers P11 and P12 configure the line unit for use with a 75Ωor
120ΩG.703 interface. Place the four-position jumper block on one of
the following:
•P11 for balanced 120Ωcircuits.
•P12 for unbalanced 75Ωcircuits (factory setting).
Line Unit Installation
To install the line unit into a shelf or remote enclosure:
1Install the line unit into the appropriate slot (1 through 16) of a shelf or
into a single-slot remote enclosure. (See “Compatibility” on page 3.)
2Connect the interface cabling and power connections using the
procedures described in the technical practice for the shelf or remote
enclosure in which the line units are installed.
3Set the DTE to the correct data rate (or keep the DTE disconnected).
Primary protection for the HDSL line must be provided by the
user. Both primary and secondary protection must be
provided by the user if the E1 line runs outside of the building.
Der primaere Schutz des HDSL Anschlusses muss von der
Benutzerseite aus geregelt werden. Wenn der E1 Anschluss
ausserhalb des Gebaeudes installiert ist, muss der primaere
und sekundaere Schutz von der Benutzerseite aus geregelt
werden.

Desktop Unit Installation
To install the desktop unit:
1Connect either the 120Ωcable or the 75Ωinput and output cables from
the DTE to the mating connectors on the ETU rear panel. The pinouts for
the 75Ωand 120Ωconnectors are listed in the following tables.
The ETU chassis must be connected to earth ground for
protection of the equipment and for personnel safety.

2Connect the HDSL line cable from the DTE to the mating connector on
the ETU rear panel. The pinouts for the HDSL line connector are listed
at the top of page 12.
3Set the DTE to the correct data rate (or keep the DTE disconnected).
HDSL STARTUP AND SYNCHRONIZATION
At startup, a WorldDSL RS LTU confirms that it is communicating with a
WorldDSL RS NTU. The LTU then synchronizes the NTU configuration
with its own configuration.
1Power up the shelf or enclosure where the units are installed.
2Confirm the following:
•The HDSL ALM LED is on and the HDSL SYNC LED flashes once
per second as the units self-configure and establish synchronization.
•After approximately 60 seconds the HDSL ALM LED is off and the
HDSL SYNC LED is steady green. The units are now ready for
configuration through the console screen menus.

(a) No other pins are used.
If the HDSL SYNC LED continues to flash after 90 seconds, the
HDSL line is faulty, the Local Unit Role is not configured as
LTU, or one of the units is not a rate-selectable unit. Check for
the correct line units and local unit role. Test the HDSL line
using the loopbacks described in user manual 700-701-100-xx.
Changing the HDSL Payload Rate or Local Unit Role causes
the unit to reset and the LEDs to cycle. Log on again by
pressing the several times (see “System Settings”
on page 16). SPACEBAR
