LTPE-UG-1017-01 Issue 1 Overview
UTU-731 List 1 and UTU-732 List 1 February 15, 2001 1
OVERVIEW
The ADC®WorldDSL™Universal Termination Units (UTUs), models
UTU-731 and UTU-732, are single-pair rate selectable High-bit-rate Digital
Subscriber Line (HDSL) unitsproduced in the Telebras form factor. Theunits
install in 20-slot Telebras shelves or in single-slot Telebras enclosures. The
units can be configured as Line Termination Units (LTUs) or Network
Termination Units (NTUs). The default configuration is NTU.
LTUs are the Exchange Office side of a repeaterless E1 transmission system.
They transport data to a remote NTU over the HDSL loop at rates of up to
2048 kbps (the standard E1 rate).
The UTU-731 and UTU-732 receive power from the Telebras shelf or
enclosure in which they are installed.
APPLICATION INTERFACE
The UTU-731 has a G.703 E1 interface that can be configured for an
impedance of 75 Ωunbalanced or 120 Ωbalanced. Data is structured or
unstructured according to the G.704 framing standard, and optionally CRC4
multiframed according to the G.706 standard. Structured mode is invoked
automatically when 1 to 31 time slots are selected. Unstructured mode is
invoked when 32 time slots are selected.
The UTU-732 has an Nx64k serial data port interface with user-selectable
protocols that conform to the V.35, V.36, X.21, or RS-530 (RS-449)
standards.
The only application mode is Single, indicating single pair.
The UTU-731 and UTU-732 have HDSL payload rates ranging from
64 kbps to 2048 kbps. The exchange office data terminal equipment (DTE)
allocates the 2048 kbps payload to the G.703 and Nx64k ports in time-slot
increments of 64 kbps each. The number of time slots allocated by the DTE
is determined by the user-selected HDSL payload rate (the DTE and HDSL
payloads must be set to the same rate).
TheHDSL systemis configuredat theLTU,eitherthroughfront-panelswitch
settings or through menu selections made at a maintenance terminal. When
using a maintenence terminal to configure the system, the menu selectionsare
applied to both the LTU and NTU. When using the front-panel switches to
configure the system, the LTUs and NTUs must be individually configured
(the switch settings are applied to the LTU and then repeated for the NTU).

SOFTWARE REQUIREMENTS
For compatibility and full use of available features, the units at each end of
the circuit (LTU and NTU) must have the same version of the software
installed.
When using Telebras form factor units with compatible non-Telebras form
factor units, the non-Telebras units must be configured on-site through a
maintenance terminal connected to the front-panel console port.
COMPATIBILITY
The UTU-731 and UTU-732 are compatible with the following ADC
WorldDSL rate selectable units:
•UTU-701C Rate Selectable Universal Termination Unit,
Part Number 150-1422-01C
•UTU-702C Rate Selectable Universal Termination Unit,
Part Number 150-1422-02C
•ETU-751C Rate Selectable ETSI Termination Unit,
Part Number 150-1432-01C
•ETU-752C Rate Selectable ETSI Termination Unit,
Part Number 150-1432-02C
FRONT PANELS
The components on the UTU-731 and UTU-732 front panels are shown in
Figure 1 on page 3.
The LEDs and pushbuttons on the UTU front panels can be used to program
system operating parameters. Their functions in the program mode and
normal mode are described in Table 1 on page 4. The indications made by the
seven segment front-panel display are described in Table 2 on page 5. The
LED status functions are described in Table 3 on page 6. For more
information, see “Front-Panel Configuration Settings”on page 12.
You can also configure the unit through a maintenance
terminal connected to the UTU console port. For more
information, see “Console Port Configuration Settings”
on page 17.

SAFETY AND EQUIPMENT REPAIR
SAFETY
To ensure your safety when servicing and installing this equipment, please
take the following precautions:
EQUIPMENT REPAIR
To ensure that the equipment does not become damaged, carefully observe
the following precaution:
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 linesand power connections
before servicing or disassembling this equipment. For
performance and safety reasons, only power supplies listed
for use with telephone equipment by a locally recognized
organization should be used with ADC equipment. All wiring
external to the product should follow the local wiring codes.
If a problem has been isolated to this unit, do not attempt to
repair it. The unit's components are not user serviceable.
Return the unit to ADC for repairs. For more information,
see “Returns”on page 74.

INSTALLATION
LTU ADDRESS SETTINGS
One Exchange Office Management Unit (EMU) can manage up to 32 HDSL
circuits, where each circuit consists of one LTU and one NTU. When one
managed shelf is used, and the number of deployed LTUs exceeds the
capacity of the 20-slot shelf, the excess LTUs can be installed in single-slot
enclosures connected to the managed shelf. The excess LTUs must then be
set for an “external address”that ranges from 21 to 32.
The location of the DIP switch used to set LTU addresses is shown in
Figure 2. The LTU address DIP switch settings are listed in Table 4 on page 9.
Figure 2. Location of LTU Address DIP Switch S700
Wear an antistatic wrist band connected to earth ground
when installing these units. Avoid unnecessary contact with
board-mounted components.
LTUs installed in a managed shelf do not require address
settings.
