OVERVIEW
This guide contains installation information for the PairGain®HiGain® Line
Unit HLU-819 List 1. The HLU-819 installs in any 3192-compliant chassis
and interfaces with the PairGainHiGain ETSI™Universal Termination Unit
UTU-814 List 1B. The HLU-819 and the UTU-814 provide the Central
Office (CO) and remote terminal (RT) sides of a repeaterless, High bit-rate
Digital Subscriber Line (HDSL). The RT provides both DSX-1 (T1) and data
interface (V.35, V.36, RS-449, X.21, or RS 530) ports to the customer (see
Figure 1). The HLU-819 accepts the respective payloads through a DSX-1
port from a multiplexer or a DS1 cross-connect shelf and transports it to the
UTU-814 List 1B at a maximum data rate of up to 1.544 Mbps. An internal
time slot assignment function splits the DS1 bandwidth between these two
ports as two Nx64K tributaries.
Figure 1. Typical HLU-819 List 1 Application
(T1 to Dual-Port Operation)
In order for the HLU-819 List 1 to support T1 transmission
over HDSL lines at the customer remote, the ETSI Remote
Enclosure ERE-811 List 2 and the UTU-814 List 1B (ETSI card)
must be used at the remote location.

Overview 350-819-200-01, Revision 01
2 November 12, 1999 HLU-819 List 1
The HLU-819 List 1 is part of the Open Span Termination Shelf (OSTS)
family of products supported by the PairGain Wideband System 3190. With
this card, the entire PairGain ETSI family of remote Customer Premise
Equipment (CPE) can be subtended to the Wideband System 3190 to provide
standard Digital Service Unit (DSU) and Channel Service Unit (CSU) data
port interfaces.
The HLU-819 fits into a 3192 mechanics shelf and conforms to ANSI
T1.403-1989 and AT&T CB 119 standards. It has a transmission range of up
to 12,000 ft. (3.66 km) when using 24 American Wire Gauge (AWG) and
9,000 ft. (2.74 km) when using 26 AWG twisted pair copper wire, including
bridged taps. The HLU-819 requires -36 to -72 Vdc from the local power
supply and can source up to 50 milliamperes (mA) on each of the HDSL data
loops to line power the remote unit.
STANDARD FEATURES
•DSX-1 (T1) interface at the CO
•DS1 (T1) and data port interfaces at the remote
•Two pair High bit-rate Digital Subscriber Line (HDSL) interface to an
ETSI remote unit
•Terminal Access Option (TAO) and Transaction Language (TL1)
command interfaces

network
•Detection of standard CSU loopup and loopdown codes
•Time slot prioritization
•Single pair operation
•Status LED
•Compatible with OSTS
•DSX-1 splitting and bridge craft access
•Line power to drive the remote unit
•Integrated dual port fractional T1 delivery system

INSTALLATION
This section provides instructions for setting up the HLU-819 and installing
the UTU-814 List 1B into the ERE-811 remote unit. The remote unit can be
powered from either the HLU-819 (must be configured) or locally, either AC
or -48 Vdc. The remote unit must be set up independently from the CO
terminal
Shelf and remote enclosure chassis ground must be
connected to earth ground to protect the equipment and for
safety of personnel.
Additional protection is required when the network side of the
equipment is extended to an outside facility.
When installing an HLU in a chassis or a UTU in a remote
enclosure, be sure to wear an antistatic wrist strap. Avoid
touching components on the circuit board.

HDSL STARTUP AND
SYNCHRONIZATION
Power-up the shelf where the HLU-819 is installed and observe the
following:
1During the power-up self test, the HLU-819 List 1 LED is a steady
yellow.IftheLEDstaysyellowformorethan 30 secondsafterpower-up,
verify the unit is not in a loopback mode. If no loopback conditions are
present, the unit has failed the self test. (See “Appendix B - Product
Support”on page 30 if assistance is required).
2The Status LED flashes green once per second as the unit attempts to
establish synchronization.
3After approximately 30 seconds, confirm one of the following:
•The Status LED is steady green, indicating the unit is synchronized
and ready to transmit and receive data. The unit can now be
configured through the maintenance terminal console screen menus.
•The Status LED continues to flash. Ifthe LED does not stop flashing
after approximately one minute, it indicates that the HDSL pair
corresponding to the indicator is experiencing an excessive signal
loss or is inan open condition. Check the line and repair if necessary.

350-819-200-01, Revision 01 System Configuration
HLU-819 List 1 November 12, 1999 11
SYSTEM CONFIGURATION
A maintenance terminal is used to access the line unit console screens and
configuration menus. Through these screens and menus, the HDSL system is
configured, monitored, tested, and its circuit inventory can be displayed.
The console screens must be viewed through the HMU-319 or Operating
System (OS) port located at the back of the Wideband System 3190, or
through a Trivial File Transfer Protocol (TFTP) session over an Ethernet
Local Area Network (LAN) connected to the chassis. The console screens
cannot be accessed through the HLU-819 because this model does not
provide a craft port.
After HDSL establishes communication with the remote unit, the HDSL
system can be configured and performance monitored from the HMU-319
management unit. Both the HLU-819 and UTU-814 are configured at this
time from the same maintenance screens. If the HDSL link is down, the only
parameters that can be changed are those on the local unit.
The HLU-819 provides a special lockout feature that prevents users
connected to the remote maintenance terminal from changing the circuit
configuration. When blocked, the maintenance screens are not accessible
from the remote craft port.
MAINTENANCE TERMINAL CONNECTION
To connect a maintenance terminal:
1ConnectastandardserialcablefromthemaintenanceterminalCOMport
to the front-panel craft port of the HMU-319. The pinouts for the craft
port and maintenance terminal connectors are shown in Figure 7 on
page 12.
HMU-819 firmware must be version 3.0 and higher.
Refer to document 150-319-107-01 for more detailed
information on terminal connections.

System Configuration 350-819-200-01, Revision 01

2Configure the maintenance terminal for the following communication
settings:
•VT100 emulation or ANSI (if VT100 is not available)
•Clear the modem initialization string if supported by the terminal
•Bits per second: 9600 (recommended)
•Data bits: 8
•Parity: None
•Stop bits: 1
•Flow Control: None
