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.

ESU LT

Chapter 1. Introduction
18 ESU LT User Manual 61200410L1-1B
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 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 oper-
ated 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 op-
eration.
• Flexible channel allocation (any starting channel and al-
ternate or contiguous).
• Remote management via 8K inband channel or 64K
dedicated TS0 (using T-Watch as the network manager).

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.
