HLU-819 List 1 November 12, 1999 1

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

•Framing insertion for transmission of framed and unframed data into T1

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

Item Function

Status LED Displays synchronization state and alarm status for HDSL

Loop.

Steady Green HDSL Loop is ready to transmit and receive data across all

spans.

Slow Blinking Green HDSL Loop acquisition is in progress for local span.

Pulsing Red •Indicates Loss of Sync Word (LOSW), Margin (MAR)

below threshold, or Errored Second (ES) count above

threshold.

•Pulses for every ES on any span.

•Indicates Loss of Clock (LOC) or DSX-1 signal, Receive

Alarm Indication Signal (RAIS), or Loss of Frame

Alignment (LFA).

Steady Yellow Indicates Local (LOC) loopback.

DSX-1 access jacks

BRG Provides non-intrusive bridging jack access to XMT and RCV

at the DSX-1 interface. Allows the two T1 payloads to be

monitored.

LINE Provides splitting jack access to Transmit (XMT) and Receive

(RCV) at the DSX-1 interface. Breaks the XMT and RCV paths

to permit test signal insertion and retrieval.

CLEI and ECI bar code

label (located on the side

of the unit)

Provides the human-readable Common Language Equipment

Identifier (CLEI) code number and the Equipment Catalog

Item (ECI) bar code number.

Configuration Number

(located on the side of the

unit)

Contains either a five- or six-digit warranty configuration

number or a standalone two- or three-digit configuration

number as follows:

•Digit 1 = Last digit of shipment year

•Digits: 2 and 3 = Shipment month

•Digits: 4 and 5 = Configuration number

The configuration number can also be found on a small bar

label that contains the Julian date code and part number. This

gummed label may be attached to the PC board or to the front

panel.
