LTPH-TP-1047-01, Issue 1 Overview
H2TU-R-402 List 5E March 12, 2001 1
OVERVIEW
The H2TU-R-402 List 5E remote unit is the customer premise side of a transmission system. The HiGain HDSL2
product family isfully compliant with the HDSL2 standardand ANSI T1/418. Providingfull-rate T1 access using
just a single copper pair, HDSL2 is a cost-effective solution that offers anopen architecture. The open architecture
inherent in HDSL2 guarantees interoperability, allowing simple and economic accommodation of network
growth.
HiGain HDSL2 products provide 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 American Wire Gauge (AWG) wire
or 9,000 feet of 26 AWG wire, including bridged taps.
FEATURES
Features specific to the List 5E include:
•Report menu option for downloading status and performance monitoring data to a file
•Enhanced loopback commands controlled by the LBK option that support
–100 inband loopdown command
–100000 (one in six) inband SMJK loopup command
•Sinks 10 mA of sealing current when connected to a compatible line unit
Standard features include:
•Line or locally powered with sealing current option
•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)
•Front-panel features
–HDSL and DS1 status Light Emitting Diodes (LEDs)
–Dual loopback control button
–DS1 access bridging jacks
–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)
–Payload (PL) and HiGain(HG) loopback source identification

•System configuration options
–Selectable DS1 pre-equalizer
–Bipolar Violation Transparency (BPVT)
–Bit Error Rate (BER) alarm
–Remote provisioning
–Selectable loopback activation codes
•Digital Data Service (DDS) latching loopback
•Line or local power with sealing current option
•Metallic loopback self tests
COMPATIBILITY
The H2TU-R-402 List 5E isdesigned to mount in any 400 or 200 mechanics shelf. Fora list of compatible shelves,
see “Appendix C - Compatibility”on page 38.
APPLICATIONS
HiGain systems provide a cost-effective, easy-to-deploy method for delivering T1 High Capacity Digital Service
(HCDS) over a single copper pair. HiGain 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.
In general, HiGain systems:
•Operate effectively inthe same cable binder group withother HDSL2 lines, HDSL, T1,ADSL, SDSL, POTS,
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.
