152-388-115-03, Issue 03 Overview
H2TU-C-388 List 1E April 21, 2000 1
OVERVIEW
The ADC HiGain®product family is the industry’s first practical implementations of High bit-rate Digital
Subscriber Line 2 (HDSL2). HiGain products are fully compliant with the HDSL2 standard. Providing full-rate
T1 access using just a single copper pair, HDSL2 is a cost-effective solution and offers an open architecture. The
open architecture inherent in HDSL2 guarantees interoperability, allowing simple, economic accommodation of
network growth.
HiGain HDSL2 products provide 1.552 Mbps transmission on one unconditioned copper pair over the fullCarrier
Service Area (CSA) range. The CSA includes loops up to 12,000 feet of 24 American Wire Gauge (AWG) wire
or 9,000 feet of 26 AWG wire, including bridged taps.
FEATURES
The H2TU-C-388 List 1E line unit is the Central Office (CO) side of a T1 transmission system.
•HDSL2 transmission features
–Lightning and power cross protection on HDSL2 interfaces
–Full duplex HDSL2 transmission on one pair at 1.552 Mbps
–Ultra-low wander (Stratum 1 compliant)
–Grounded loop detection on High-bit-rate Digital Subscriber Line 2 (HDSL2)
•Front-panel provisioning features
–Four-character status display
–Status LED
–RS-232 craft port for connection to a maintenance terminal
•HiGain HDSL2 maintenance screens for inventory, provisioning, and troubleshooting
–High-performance, non-volatile performance monitoring
–Non-volatile alarm histories
–Performance Report Messaging (PRM) support for Supplemental PRM (SPRM) and Network PRM
(NPRM) at the H2TU-R
•Configuration options
–Selectable DS1 pre-equalizer
–Bipolar Violation Transparency (BPVT) options
–Bit Error Rate (BER) alarm
–Loss of Signal/Alarm Indication Signal (LOS/AIS) payload alarm option
–Remote provisioning
–Selectable loopback activation codes
•Compatible with Double Dual Module Plus (DDM+) high-density shelves
•Flash download of firmware updates
•Digital Data Service (DDS) latching loopback
•Payload (PL) and HiGain (HG) loopback source identification
•Network Management and Administration (NMA) interface

•Margin threshold alarm
COMPATIBILITY
The H2TU-C-388 is designed to mount in DDM+ high-density shelves. For a list of compatible shelves, see
“Appendix C - Compatibility” on page 62.
APPLICATIONS
HiGain HDSL2 systems provide a cost-effective, easy-to-deploy method for delivering DS1 High Capacity
Digital Service (HCDS) over a single copper pair. HiGain HDSL2 systems support a multitude of network
connections and system models. See Figure 1 on page 3.
•The service is deployed over one unconditioned, non-loaded copper pair.
•Conventional inline T1 repeaters are no longer required.
•Cable pair conditioning, pair separation, and bridged tap removal are not required.
Each loop has no more than 35 dB of loss at 196 kHz, with driving and terminating impedances of 135 Ω.In
general, HiGain HDSL2 systems:
•Operate effectively in the samecable binder group withother HDSL2 lines, HDSL,T1, ADSL, SDSL, POTS,
Digital Data Service (DDS), and other transmission schemes.
•Can be used with customers requiring DS1 service on a temporary or permanent basis.
•Provide a means of quickly deploying service in advance of fiber-optic transmission systems.
DS1 is used throughout this document to refer to either the remote unit’s DS1 interface or the
line unit’s DSX-1 interface.
