The ADC
®
WorldDSL™ G.S ETU-911A, ETU-912A, and ETU-914A ETSI
Termination Units (ETUs) are rate selectable Single-pair High-speed Digital
Subscriber Line (SHDSL) cards housed in enclosures with rear-panel interface and
power connectors for use as standalone desktop units
. The SHDSL cards conform to
ITU-T recommendation G.991.2 for SHDSL (referred to as G.SHDSL).
Rate selectable G.SHDSL offers an extended transmission range and spectral
compatibility with leading DSL technologies.
Transmission ranges vary
according to the data rate selected, wire size, and noise environment. At a data
rate of 2.048 Mbps with noise, the reach is 2.4 km (1.4 mile) on 0.4 mm wire
and 6.8 km (4.2 miles) on 8 mm wire. Reach is significantly greater at lower
data rates in reduced noise environments. For details, see the UTU/ETU User
Manual, LTPE-UM-3010-xx (which can be downloaded from the ADC
website at www.adc.com).
The ETUs can be configured as Line Termination Units (LTUs) or Network
Termination Units (NTUs). The default configuration is NTU.
The NTU-configured ETUs are installed at the customer site. LTU-configured
Universal Terminations Units, UTU-911, UTU-912, and UTU-914, are installed in
exchange office shelves. To complete the G.SHDSL transmission system, the UTUs
and ETUs are interconnected over one pair of twisted-copper wire.
The UTUs accept the exchange office payload at their G.703 or Nx64k port and
transport the payload to the ETUs at the selected DSL data rate. The DSL data rate is
determined by the number of 64 kbps time slots selected by the user. The UTUs and
ETUs have a DSL data rate ranging either from 192 kbps to 2.048 Mbps (G.703) or
from 192 kbps to 2.304 Mbps (Nx64k).
The ETUs require a 50 or 60 Hz power source with a voltage range of 100 to 240 Vac.
The ETUs include a power-fail circuit that triggers a user-configured alarm and
reports same to the exchange office when an AC power failure occurs.
APPLICATION INTERFACE
The ETU-911A has an E1 G.703 interface that can be configured for an
impedance of 75Ω unbalanced or 120Ω balanced. Data is structured or
unstructured according to the G.704 framing standard and, optionally,
CRC-4 multiframed according to the G.706 standard.
The ETU-912A has an Nx64k serial dataport interface with user-selectable
protocols that conform to the V.35, V.36, X.21, or RS-530 (RS-449)
standards. The ETU-914A has both an E1 G.703 interface and an Nx64k
interface, sharing the SHDSL bandwidth.
Use of this product in a manner other than defined in this

REAR-PANEL CABLE CONNECTIONS
Make the following rear-panel cable connections:
1 Connect the cable containing the SHDSL pair to the SHDSL line connector.
2 If the customer equipment uses 75Ω coaxial cable, connect the equipment's output
cable to the 75Ω IN connector. Connect the equipment's input cable to the 75Ω OUT
connector.
3 If the customer equipment uses 120Ω twisted-pair cable, connect the cable to the
120Ω\ALARM connector.
4 If the customer equipment uses an Nx64k serial interface (V.35, V.36, RS-449,
RS-530, or X.21), connect its cable to the DATA PORT connector.
5 If using an external power-fail alarm, fabricate a cable that connects alarm-relay
pins 5 (NC), 7 (NO), and 14 (C) of the ALARM connector to the external alarm (the
ALARM connector is designated 120Ω\ALARM on ETU-911A and ETU-914A).
DSL SELF TEST AND LINK UP
The LTU-configured unit holds the configuration settings for both itself and the remote
NTU-configured unit. As the two units synchronize, the LTU will configure the NTU.
1 Power up the SHDSL unit.
2 Confirm the following:
• The red ALM LED is on and the green SYNC LED flashes once per second as
the units self-configure and establish synchronization.
• After approximately 60 seconds, the red ALM LED is off, and the SYNC LED is
a steady green. The unit is now ready for configuration using the console screen
menus displayed on a maintenance terminal at the exchange office.

The ADC
®
WorldDSL™ G.S ETU-911A, ETU-912A, and ETU-914A ETSI
Termination Units (ETUs) are rate selectable Single-pair High-speed Digital
Subscriber Line (SHDSL) cards housed in enclosures with rear-panel interface and
power connectors for use as standalone desktop units
. The SHDSL cards conform to
ITU-T recommendation G.991.2 for SHDSL (referred to as G.SHDSL).
Rate selectable G.SHDSL offers an extended transmission range and spectral
compatibility with leading DSL technologies.
Transmission ranges vary
according to the data rate selected, wire size, and noise environment. At a data
rate of 2.048 Mbps with noise, the reach is 2.4 km (1.4 mile) on 0.4 mm wire
and 6.8 km (4.2 miles) on 8 mm wire. Reach is significantly greater at lower
data rates in reduced noise environments. For details, see the UTU/ETU User
Manual, LTPE-UM-3010-xx (which can be downloaded from the ADC
website at www.adc.com).
The ETUs can be configured as Line Termination Units (LTUs) or Network
Termination Units (NTUs). The default configuration is NTU.
The NTU-configured ETUs are installed at the customer site. LTU-configured
Universal Terminations Units, UTU-911, UTU-912, and UTU-914, are installed in
exchange office shelves. To complete the G.SHDSL transmission system, the UTUs
and ETUs are interconnected over one pair of twisted-copper wire.
The UTUs accept the exchange office payload at their G.703 or Nx64k port and
transport the payload to the ETUs at the selected DSL data rate. The DSL data rate is
determined by the number of 64 kbps time slots selected by the user. The UTUs and
ETUs have a DSL data rate ranging either from 192 kbps to 2.048 Mbps (G.703) or
from 192 kbps to 2.304 Mbps (Nx64k).
The ETUs require a 50 or 60 Hz power source with a voltage range of 100 to 240 Vac.
The ETUs include a power-fail circuit that triggers a user-configured alarm and
reports same to the exchange office when an AC power failure occurs.
APPLICATION INTERFACE
The ETU-911A has an E1 G.703 interface that can be configured for an
impedance of 75Ω unbalanced or 120Ω balanced. Data is structured or
unstructured according to the G.704 framing standard and, optionally,
CRC-4 multiframed according to the G.706 standard.
The ETU-912A has an Nx64k serial dataport interface with user-selectable
protocols that conform to the V.35, V.36, X.21, or RS-530 (RS-449)
standards. The ETU-914A has both an E1 G.703 interface and an Nx64k
interface, sharing the SHDSL bandwidth.
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
