LTPH-UM-1072-03 Overview
H2TU-C-202 List 2F October 25, 2002 1
OVERVIEW
The H2TU-C-202 List 2F line unit is the Central Office (CO) side of a T1 transmission system. The HiGain™
HDSL2 product family is fully compliant with the HDSL2 standard ANSI T1.418-2000. Providing full rate T1
access using just a single copper pair, HDSL2 is a cost-effective solution that offers an open architecture. The open
architecture inherent in HDSL2 guarantees interoperability allowing simple and economic accommodation of
network growth.
HiGain HDSL2 products provide 1.544 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 wire or 9,000 feet of 26 AWG
wire, including bridged taps.
FEATURES
Enhanced features include:
•Report menu option for downloading status and performance monitoring data to a file
•Dual front-panel loopback commands
•Additional Loopback Timeout (LBTO) settings of 8 hours and 24 hours
•16-bit inband retrieval of margin and loop attenuation
Standard features include:
•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 (for Stratum 1 transport)
–Grounded loop detection on High-bit-rate Digital Subscriber Line 2 (HDSL2)
•Front-panel features
–Four-character status display
–DS1 bridging access
–Status Light Emitting Diode (LED)
–RS-232 craft port for connection to a maintenance terminal
•Maintenance screens for inventory, provisioning, and troubleshooting
–Non-volatile DS1 and HDSL2 performance monitoring and alarm histories
–Performance Report Messaging (PRM) support for Supplemental PRM (SPRM) and Network PRM
(NPRM) at the H2TU-R
–Payload (PL) and HiGain (HG) loopback source identification
–Margin Alarm (MAL) threshold
–Remote provisioning through TL1 FDL or 11-bit payload commands
•Configuration options
–Selectable DSX-1 pre-equalizer
–Bipolar Violation Transparency (BPVT) option
–Bit Error Rate (BER) alarm

Overview LTPH-UM-1072-03
2 October 25, 2002 H2TU-C-202 List 2F
–Power Back Off Network (PBON) and Power Back Off Customer (PBOC) options for configuring
HDSL2 transmit power levels
–Loss of Signal/Alarm Indication Signal (LOS/AIS) payload alarm
–Selectable loopback activation codes
•Network Management and Administration (NMA) interface
COMPATIBILITY
The H2TU-C-202 List 2F is designed to mount in 200 and 400 mechanics, high-density shelves. For a list of
compatible shelves, see “Appendix C - Compatibility” on page 67.
APPLICATIONS
HiGain HDSL2 systems provide a cost-effective, easy-to-deploy method for delivering T1 High Capacity Digital
Service (HCDS) over a single copper pair. HiGain HDSL2 systems support a multitude of network connections
and system models.
•The service is deployed over one unconditioned, non-loaded copper pair.
•Conventional inline DS1 repeaters are no longer required.
•Cable pair conditioning, pair separation, and bridged tap removal are not required.
Each loop should have no more than 35 dB of insertion loss at 196 kHz, with driving and terminating impedances
of 135Ω. In general, HiGain HDSL2 systems:
•Operate effectively in the same cable binder group with other HDSL2 lines, HDSL, DS1, 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.
