container.
SAFETY
To ensure your safety when servicing and installing this equipment, please
take the following precautions:
Input voltage for the UTU-801, UTU-802, and UTU-804 List 5
line units (nominal -48 Vdc, tolerance -36 to -72 Vdc) must
be supplied by an isolated DC source that complies with
TNV or earthed SELV requirements of the latest version of
IEC 950.
Be careful when installing or modifying telephone lines.
Dangerous voltages can be present. It is unsafe to install
telephone wiring during a lightning storm.
Always disconnect all telephone lines and power connections
before servicing or disassembling this equipment. All wiring
external to the product should follow the local wiring codes.

350-819-300-01, Revision 01 Overview
ELU-819 List 1 January 10, 2000 1
OVERVIEW
PairGain®HiGain-ETSI™ Line Unit ELU-819 List 1 installs in any
3192-compliant chassis and interfaces with the HiGain-ETSI Universal
Termination Units UTU-801 List 5, UTU-802 List 5, and UTU-804 List 5.
The ELU-819 and the UTUs provide the Central Office (CO) and remote
terminal (RT) sides of a repeaterless, High bit-rate Digital Subscriber Line
(HDSL), respectively. The RT provides both E1 (G.703) and data interface
(V.35, V.36, RS-449, X.21, or RS-530) ports to the customer (see Figure 1).
The ELU-819 accepts the respective payloads through a E1 port from a
multiplexer or a cross-connect shelf and transports it to the UTU-801 List 5,
UTU-802 List 5, or UTU-804 List 5 at a maximum data rate of up to 2.048
Mbps. An internal time-slot assignment function splits the E1 bandwidth
between these two ports as two Nx64K tributaries.
Figure 1. Typical ELU-819 List 1 Application (E1 to Dual-Port Operation)
For the ELU-819 List 1 to support E1 transmission over HDSL
lines at the customer remote, the ETSI Remote Enclosure
ERE-811 List 2 and the UTU-801 List 5, UTU-802 List 5, or
UTU-804 List 5 (ETSI cards) must be used at the remote
location.

Overview 350-819-300-01, Revision 01
2 January 10, 2000 ELU-819 List 1
The ELU-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), which includes UTU-801, UTU-802, and UTU-804 List 5,
can be subtended to the Wideband System 3190 to provide standard Digital
Service Unit (DSU) and Channel Service Unit (CSU) data port interfaces.
The ELU-819 fits into a 3192 mechanics shelf and conforms to ANSI
T1.403-1989 and AT&T CB 119 standards. The ELU-819 requires -36 to -72
Vdc from the local power supply and can source up to 60 milliamperes (mA)
on each of the HDSL data loops to line power the remote unit.
Transmission ranges are based on a signal attenuation of 35 dB at 292 kHz
with 135 Ωterminations, and assume the presence of noise according to the
model described in ETSI specification TS 101 135. The expected Bit Error
Rate (BER) under this noise model is less than 1x10-7. The reach of the
system in such a noise environment is 2.8 km (1.74 miles) over 0.4 mm [26
American Wire Gauge (AWG)] or 3.35 km (2.08 miles) over
0.51 mm (24 AWG) twisted-pair copper wire.
The ELU-819 List 1 has the following standard features:
•E1 interface at the CO
•E1 interface 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 data into E1 network
•HDB3 line code
•Time-slot prioritization on loss of one pair
•Point-to-multipoint transport
•Status LED
•Compatible with OSTS
•E1 splitting and bridge access
•Line power to drive the remote unit
•Integrated dual port fractional E1 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 E1 signal, Receive Alarm
Indication Signal (RAIS), or Loss of Frame Alignment (LFA).
Steady Yellow Indicates ELU loopback is in effect.
E1 (G.703) access jacks
BRG Provides non-intrusive bridging jack access to XMT and RCV
at the E1 interface. Allows the two E1 payloads to be
monitored.
LINE Provides splitting jack access to Transmit (XMT) and Receive
(RCV) at the E1 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.

INSTALLATION
This section provides instructions for setting up the ELU-819 and installing
the UTU-801 List 5, UTU-802 List 5, or UTU-804 List 5 into the ERE-811
List 2 remote unit. The remote unit can be powered from either the ELU-819
(must be configured) or locally, using either 110 Volts, Alternating Current
(VAC) or -48 Vdc power. The remote unit must be setup independently from
the CO terminal if the HDSL loops are down and the remote is powered
locally.
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 ELU in a chassis or UTU in a remote
enclosure, be sure to wear an antistatic wrist strap. Avoid
touching components on the circuit board.

ENCLOSURE
UTU Jumper Settings
Jumpers must be set on the UTU units if using a 120 Ωinterface or if
groundingyour G.703 cables at the data port onthe shelfor remoteenclosure.
The locations of these jumpers (P8, P11, and P12) are shown in Figure 5.
Figure 5. Jumper Locations

350-819-300-01, Revision 01 Installation
ELU-819 List 1 January 10, 2000 9
To set the jumpers on the UTU line units:
1Jumper P8 complies with the ITU G.703 requirement that an option be
provided to allow the connection of the outer conductor of the coaxial
pair or the screen of the symmetrical pair to earth (frame) ground at the
G.703 input data port. Do one of the following:
•Do not install a jumper. This is the factory setting and provides the
standard G.703 input port interface. Cable grounding is not used.
•Short P8 pins 1 and 2 if grounding the screen of the 120 Ωcable.
•Short P8 pins 2 and 3 if grounding the outer conductor of the
75 Ωinput cable.
2Jumpers P11 and P12 configure the line unit for use with a 75 Ωor
120 ΩG.703 interface (see Figure 7 on page 11). Place the four-position
jumper block on one of the following:
•P11 for balanced 120 Ωcircuits
•P12 for unbalanced 75 Ωcircuits (factory setting)
