Chapter 1 Introduction
ESU LT OVERVIEW
This section provides a functional description of the ESU LT,
describes its features, and illustrates its four interfaces.
Functional Description
The ADTRAN ESU LT (Figure 1-1) is one of several E1
CSU/DSUs that offer complete flexibility for connection of various
data sources to E1 or FE1 facilities. This family of ESU products
includes the following:
• ESU LT - E1 CSU/DSUs with a single Nx56K/64K serial port.
• ESU 120e - Same as the ESU LT with the added feature of a
G.703 drop port and a slot in the rear panel to house an option
module. Each module offers up to four additional data ports.

Figure 1-1. ESU LT Unit
The ESU LT serves as the link between user data sources such as
local area network (LAN) bridges and routers, computers, CAD
systems, and teleconferencing equipment. The amount of
61200410L2-1A ESU LT User Manual 17
bandwidth allocated to the port is user-programmable. The data
terminal equipment (DTE) data can occupy contiguous or alternate
channels in the E1 stream, and the channels may start at any
position.
ESU LT Features
• An E1 interface and an Nx56/64 DTE serial interface port.
• Easy configuration capabilities using simplistic menus displayed in a liquid crystal display (LCD) window operated by a
front panel keypad.
• Data port supports V.35, EIA-530, V.36, and X.21 electrical interfaces.
• Selectable timing from the network, the Nx56/64 DTE port, or
internally.
• All ones, all zeros, 511, QRSS, and 1:8 test patterns.
• Extensive self-testing and monitoring ensures proper operation.
• Flexible channel allocation (any starting channel and alternate
or contiguous).
• Remote management via 8K inband channel or 64K dedicated
TS0 (using T-Watch as the network manager).
Chapter 1. Introduction
ESU LT CONFIGURATION APPLICATION
The following example illustrates a possible ESU LT application.
Bridge/Router Application
A bridge or router can be interfaced to the network by
using the DTE interface. The bandwidth used is programmable at
Nx56 or Nx64 data rates for E1 or FE1 service. The bandwidth can

be selected as contiguous or alternate. Figure 1-2 shows a simple
bridge application.

Receipt Inspection
Carefully inspect the ESU LT for any shipping damage. If damage
is suspected, file a claim immediately with the carrier and then
contact ADTRAN Customer Service. If possible, keep the original
shipping container for use in shipping the ESU LT back for repair
or for verification of damage during shipment.
ADTRAN Shipments Include
The following items are included in the ADTRAN shipment:
•ESU LT unit
• DB-15 to BNC adapter

Ω DB-15 network interface
POWER CONNECTION
Power is supplied to the ESU LT through an IEC-type power
connector on the rear of the unit.
Power to the ESU LT must be from a grounded 90-240 VAC, 50/60 Hz
power source.
Grounding Instructions
Grounding instruction information from the Underwriters'
Laboratory UL 1950 3rd Edition is provided in this section. An
equipment grounding conductor that is not smaller in size than the
ungrounded branch-circuit supply conductors is to be installed as
part of the circuit that supplies the product or system. Bare,
covered, or insulated grounding conductors are acceptable.
Individually covered or insulated equipment grounding conductors
shall have a continuous outer finish that is either green, or green
with one or more yellow stripes. The equipment grounding
conductor is to be connected to ground at the service equipment.
Chapter 2. Installation
The attachment-plug receptacles in the vicinity of the product or
system are all to be of a grounding type, and the equipment
grounding conductors serving these receptacles are to be connected
to earth ground at the service equipment. A supplementary
equipment grounding conductor shall be installed between the
product or system and ground that is in addition to the equipment
grounding conductor in the power supply cord.
The supplementary equipment grounding conductor shall not be
smaller in size than the ungrounded branch-circuit supply
conductors. The supplementary equipment grounding conductor
shall be connected to the product at the terminal provided, and shall
be connected to ground in a manner that will retain the ground
connection when the product is unplugged from the receptacle. The
connection to ground of the supplementary equipment grounding
conductor shall be in compliance with the rules for terminating
bonding jumpers at Part K or Article 250 of the National Electrical
Code, ANSI/NFPA 70. Termination of the supplementary
22 ESU LT User Manual 61200410L2-1A
Chapter 2. Installation
equipment grounding conductor is permitted to be made to building
steel, to a metal electrical raceway system, or to any grounded item
that is permanently and reliably connected to the electrical service
equipment ground.
Bare, covered, or insulated grounding conductors are acceptable. A
covered or insulated grounding conductor shall have a continuous
outer finish that is either green, or green with one or more yellow
stripes.
The supplemental grounding conductor shall be connected to the
equipment using a number 8 ring terminal. The terminal should be
fastened to the grounding lug provided on the rear panel of the
equipment. The ring terminal should be installed using the
appropriate crimping tool (AMP P/N 59250 T-EAD Crimping Tool
or equivalent).
