FCC Class A Compliance
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant
to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment. This equipment generates,
uses, and can radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in which case the user will be
required to correct the interference at his own expense.
Limited Warranty
Product warranty is determined by your service agreement. Contact your sales representative or
Customer Service for details.
Modifications
Any changes or modifications made to this device that are not expressly approved by ADC DSL
Systems, Inc. voids the user's warranty.
All wiring external to the products should follow the provisions of the current edition of the National
Electrical Code.

H2TU-C-388 LIST 1D
The HiGain®product family is the industry’s first practical implementation of High
bit-rate Digital Subscriber Line 2 (HDSL2). When an H2TU-C-388 List 1D line unit
is used in conjunction with a HiGain remote unit (H2TU-R), the system provides
1.552 Mbps transmission on one unconditioned copper pair over the full Carrier
Service Area (CSA) range. The CSA includes loops up to 12,000 feet of 24 AWG or
9,000 feet of 26 AWG wire, including bridged taps.
FEATURES
SPECIFICATIONS
•Front-panel status and alarm LEDs, DSX-1
access jacks, and craft port •Payload or HiGain loopback source identification
•Ultra-low wander •Bit Error Rate (BER) alarm option
•Three-span range with two regenerators

HDSL2 Line Rate 1.552 Mbps Overlapped Pulse Amplitude Modulation
Transmission with Interlocking Spectra (OPTIS)
HDSL2 Output +16.8 dBm ±0.5 dB, 135 Ω
Maximum Loop Attenuation 35 dB at 196 kHz, 135 Ω

DSX-1 Pulse Output 6 V pk-pk, pre-equalized for 0 to 655 feet of ABAM cable
DSX-1 Input Level +1.5 to -7.5 dB DSX
INSTALLATION
To ensure proper installation of the H2TU-C, align the H2TU-C with the enclosure
slot guides, and slide the unit in. Push down on the front panel to properly seat it.
Set the S1 switch bank to the desired configuration for line equalization. For
information about line equalization, refer to the H2TU-C-388 List 1D technical
practice, document number 152-388-114-xx.
POWER-UP SEQUENCE
When the H2TU-C powers up, the status and alarm LEDs illuminates and report
status.
If the H2TU-C is unable to communicate with the next span device, it displays various
alarm and status indicators on the front panel LEDs.
If the H2TU-C is able to communicate with the next span device, the following occurs:
1The Status LED flashes green while acquiring each device in the system, and
turns a steady green when the entire system is operating without any alarms. (The
T1 signal must be present.)
2If any alarm conditions exist after the system powersup, these are reported on the
status and alarm LEDs. (The H2TU-C reports alarms if no T1 signal is applied.)
PROVISIONING
After installing the H2TU-C, perform these basic provisioning tasks by accessing the
HiGain HDSL2 logon screen. Refer to the onscreen Help menu for navigational aids.
1Connect a maintenance terminal to the craft port (see front-panel illustration
inside), then press + to refresh the logon screen, if necessary.
2Select the Config menu, Date and Time, and type the date and time.
3Select the Inventory menu and type in the unit ID numbers.
4Change the settings of any system parameters, if necessary, by selecting the
Config menu, Standard Options or PairGain Options.
5Once the H2TU-C is successfully installed and provisioned, access the Monitor
or Performance menus to clear the Performance and Alarm History screens to
ensure useful data.

DS1 Line Coding DS1 B8ZS Places both the H2TU-C and H2TU-R into their B8ZS modes.
AMI Places both the H2TU-C and H2TU-R into their AMI modes.
H2TU-C Equalization EQL 0Sets the Equalizer to DSX-1 for 0 to 132 feet.
133 Sets the Equalizer to DSX-1 for 133 to 265 feet. 266 Sets the Equalizer to DSX-1 for 266 to 398 feet. 399 Sets the Equalizer to DSX-1 for 399 to 532 feet. 533 Sets the Equalizer to DSX-1 for 533 to 655 feet.
H2TU-R Line Buildout RLBO 0 dB Sets the DS1 receive leveloutput toward the Customer Interface

-7.5 dB Sets the DS1 receive level output toward the CI to -7.5 dB. -15.0 dB Sets the DS1 receive level output toward the CI to -15.0 dB.
Alarm Pattern ALMP AIS Enables the HiGain Solitaire system to output an AIS payload at
its T1 ports for LOSW and T1 LOS.
LOS Enables the HiGain Solitaire system to output an LOS condition
at its T1 ports for LOSW and T1 LOS.
H2TU-R TLOS Loopback
TLOS ENA Enables a logic loopback at the H2TU-R when an LOS occurs at
its DS1 input, if enabled at the H2TU-R.
DIS Disables Transmit Loss of Signal (TLOS) logic loopback.
Network Loopback Pattern
NLBP AIS Enables the H2TU-R to transmit an AIS towards CI for any
network loopback.
LOS Enables the H2TU-R to transmit an LOS towards CI for any
network loopback.
To comply with the intrabuilding wiring requirements of GR-1089 CORE, Section 4.5.9, the shields of the ABAM-type cables that connect the H2TU-C-388 List 1D DSX-1 output ports to the cross-connect panel must be grounded at both ends.

H2TU-C-388 LIST 1D
The HiGain®product family is the industry’s first practical implementation of High
bit-rate Digital Subscriber Line 2 (HDSL2). When an H2TU-C-388 List 1D line unit
is used in conjunction with a HiGain remote unit (H2TU-R), the system provides
1.552 Mbps transmission on one unconditioned copper pair over the full Carrier
Service Area (CSA) range. The CSA includes loops up to 12,000 feet of 24 AWG or
9,000 feet of 26 AWG wire, including bridged taps.
FEATURES
SPECIFICATIONS
•Front-panel status and alarm LEDs, DSX-1
access jacks, and craft port •Payload or HiGain loopback source identification
•Ultra-low wander •Bit Error Rate (BER) alarm option
•Three-span range with two regenerators

•Grounded loop detection •Flash download of firmware updates
•Loss of Signal (LOS)/Alarm Indication Signal
(AIS) payload alarm option •Performance Report Messaging (SPRM and NPRM)
•HiGain maintenance screens for inventory,
provisioning, troubleshooting, and
performance monitoring
•Digital Data Service (DDS) latching loopback

Operating Temperature -40 °F to +149 °F (-40 °C to +65 °C)
Operating Humidity 5% to 95% non-condensing
HDSL2 Span Voltage 0, -185 Vdc
Mounting 3192 high-density shelf
HDSL2 Line Rate 1.552 Mbps Overlapped Pulse Amplitude Modulation
Transmission with Interlocking Spectra (OPTIS)
HDSL2 Output +16.8 dBm ±0.5 dB, 135 Ω
Maximum Loop Attenuation 35 dB at 196 kHz, 135 Ω
DSX-1 Line Rate 1.544 Mbps ±200 bps
DSX-1 Line Format Alternate Mark Inversion (AMI) or Bipolar with 8-zero
Substitution (B8ZS)
DSX-1 Frame Format Extended SuperFrame (ESF), SuperFrame (SF), or
Unframed (UNFR)
DSX-1 Pulse Output 6 V pk-pk, pre-equalized for 0 to 655 feet of ABAM cable
DSX-1 Input Level +1.5 to -7.5 dB DSX
INSTALLATION
To ensure proper installation of the H2TU-C, align the H2TU-C with the enclosure
slot guides, and slide the unit in. Push down on the front panel to properly seat it.
Set the S1 switch bank to the desired configuration for line equalization. For
information about line equalization, refer to the H2TU-C-388 List 1D technical
practice, document number 152-388-114-xx.
POWER-UP SEQUENCE
When the H2TU-C powers up, the status and alarm LEDs illuminates and report
status.
If the H2TU-C is unable to communicate with the next span device, it displays various
alarm and status indicators on the front panel LEDs.
If the H2TU-C is able to communicate with the next span device, the following occurs:
1The Status LED flashes green while acquiring each device in the system, and
turns a steady green when the entire system is operating without any alarms. (The
T1 signal must be present.)
2If any alarm conditions exist after the system powersup, these are reported on the
status and alarm LEDs. (The H2TU-C reports alarms if no T1 signal is applied.)
PROVISIONING
After installing the H2TU-C, perform these basic provisioning tasks by accessing the
HiGain HDSL2 logon screen. Refer to the onscreen Help menu for navigational aids.
1Connect a maintenance terminal to the craft port (see front-panel illustration
inside), then press + to refresh the logon screen, if necessary.
2Select the Config menu, Date and Time, and type the date and time.
3Select the Inventory menu and type in the unit ID numbers.
4Change the settings of any system parameters, if necessary, by selecting the
Config menu, Standard Options or PairGain Options.
5Once the H2TU-C is successfully installed and provisioned, access the Monitor
or Performance menus to clear the Performance and Alarm History screens to
ensure useful data.
