Customer Support
Thank you for your purchase of the Telebyte Model 458-3SL (3-Slot Chassis).
This compact unit is extremely easy to use and a perfect fit when only one, two
or three line modules are required. The Model 458-3SL is ideally suited for
testing DSL modems and other bandwidth-compliant telecom devices in a high-
volume production line environment. When used in conjunction with up to three
8-channel 458 Line Modules, it becomes a 24-channel local loop simulator. The
built-in Control Module interfaces with a PC or terminal via IEEE-488 or RS-
232/Ethernet to control loop-length settings or it can be used as a stand-alone
unit. User-command language may be used for control. In addition, line length is
displayed on the front of the unit and can be set via a keypad on the front panel.

1.0 Introduction
The Model 458-3SL (3-Slot Chassis) is a compact, versatile unit that accepts 1, 2 or 3 line modules
and controls from 1 - 24 channels. It is ideal for testing DSL modems and other bandwidth-compliant
telecom devices in a high-volume production environment. While it can be used as a stand-alone unit,
the built-in Control Module interfaces with a PC via RS-232, IEEE-488, or Ethernet. Line lengths and
configuration settings appear on an LCD display on the front of the unit and can be set via a keypad.
For added convenience, the Control Module firmware is field-upgradeable through the RS-232 port.
The same software is used for the 458-CM (16-Slot chassis).
The Model 458-3SL is used with our advanced 458 Line Modules that simulate several cable types
and offer the bandwidth requirements for today’s xDSL technologies such as varieties of ADSL,
ADSL2+ and VDSL2. User-friendly GUIs (included with line modules) provide another means of
controlling loop lengths and communication parameters. For more information about Telebyte’s plug-
in line modules, refer to the individual datasheets or manuals.
Chassis/Control Module
The Chassis may be mounted in a standard 19-in rack and accepts a maximum of three Line
Modules.
The front of the Model 458-3SL is shown with three line modules installed (not included).
Note that the slot number designations begin with 1 at the top of the unit.
Model 458-3SL (3-Slot Chassis) Rev A Page 2
The image above shows the rear of the 458-3SL rear with three line modules installed (not included).
Note the three types of connectors are RS232, IEEE-488 and Ethernet. In addition, the power connector
door houses the fuses and voltage selector needed to change the AC Input voltage (if required).
The built-in Control Module is used to configure a Line Module to a particular length via a pushbutton
keypad on the front of the unit. The user may also use the IEEE-488, RS-232 or Ethernet port for
control. When configured for IEEE-488, the Model 458-3SL can be operated from an IEEE Controller
such as a PC equipped with an IEEE interface board. In RS-232 mode, the unit can be connected to
any RS-232 device (e.g., a terminal or PC) that has a terminal emulation program such as Hyper
Terminal installed. In RS-232/Ethernet mode, RS-232 commands are sent over an Ethernet
connection. This allows a remote PC connected to a LAN to communicate with the 458-3SL.
LIn order to send RS-232 commands over an Ethernet connection, this feature must be
enabled. Refer to section 6.0 Enabling RS-232/Ethernet Control for detailed
instructions.
Line Module Series
A maximum of three Model 458 Line Modules (sold separately) can be placed into the chassis. Each
458 Line Module can be individually set by the Control Module. Communications between the Control
Module and the 458 Line Module are via a backplane. The backplane will pass power and the signals
to control the length of each card. The RJ-45 connectors used to connect to the unit to be tested are
mounted directly on the 458 Line Module. Telebyte provides GUI software for a user-friendly interface
when configuring 458 Line Modules (available for download from our Web site at
www.telebytebroadband.com). Refer to the individual documentation for more information on our Line
Module series.

5.0 Enabling RS-232/Ethernet Controls
Overview
RS-232 commands may be sent over an Ethernet connection to control the Model 458-3SL. This is
made possible by a Lantronix XPort transceiver installed in the unit. A one-time set up must be
performed to assign an IP address to the transceiver and configure a virtual COM port. This is all
done using a remote PC. It requires one software installation to assign an IP address to the
transceiver and a second one to configure the virtual COM port. Once this is done, all of the
commands available in section 4.0 RS-232/Ethernet Controls may be used over the Ethernet
connection.
Before You Begin
Connect the 458-3SL and a remote PC to the LAN using Ethernet cables. Please note, when
connecting the Model 458-3SL directly to a PC a crossover Ethernet cable is used for communication;
when connecting to a network (through a switch or router) a straight-through Ethernet cable is used.
LAdministrator access to the remote PC is required.
Model 458-3SL (3-Slot Chassis) Rev A Page 15
Installing IP Address Assignment Software
The IP address assignment software (Lantronix DeviceInstaller) is obtained from the CD supplied with
your unit or downloaded from www.telebytebroadband.com (select Support/Software option). It is
then copied to the remote PC and expanded. After installation, it is used to assign an IP address to
the XPort.
Obtain the IP address and subnet mask for the XPort from your network administrator as it is needed
during the assignment process. In addition, note the MAC address of the XPort which is located on
the back of the 458-3SL. This address allows the assignment software to locate the XPort.
LIn some cases, firewall protection on the PC may interfere with the installation or
assignment process. If this occurs, contact your network administrator.
Install Software
1. Copy the XPort_DeviceInstaller_x.x.x.x.zip file to a folder on the remote PC such as
C:\Temp (where x.x.x.x represents the latest version of the software).
2. Expand the zip file using software such as WinZip or PKZip.
3. Navigate to the folder that contains the contents of the expanded .zip file.
4. Double-click on the Setup.Exe program file. The Setup screen is shown.
5. Click Next. The Select Installation Folder screen is shown.
