Customer Support
Thank you for your purchase of the Telebyte Model 458-CC-16/458-CM (16-Slot
Chassis & Control Module). This versatile product provides a wide variety of
configurations through the use of up to 16 plug-in Line Modules. The Model 458-
CC-16/458-CM 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 16, 8-channel 458 Line Modules, it becomes a
128-channel local loop simulator. The 458-CM Control Module interfaces with a
PC or terminal via IEEE-488 or RS-232/Ethernet to control loop-length settings or
the 458-CC-16/458-CM 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-CC-16/458-CM (16-Slot Chassis & Control Module) accepts 1 - 16 line modules and
controls from 1 - 128 channels. It is ideal for testing DSL modems and other bandwidth-compliant
telecom devices in a high-volume production environment. While the 458-CC-16/458-CM can be used
as a stand-alone unit, the 458-CM 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 458-CM firmware is field-upgradeable through the RS-232
port.
The Model 458-CC-16/458-CM 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.
While the 458-CC-16 (16-Slot Chassis) and 458-CM (Control Module) are purchased
separately, they are both addressed in this manual, together or separately, as required.
Chassis
The 458-CC-16 may be mounted in a standard 19-in rack and accepts a maximum of 16 Line
Modules.
The front of the Model 458-CC-16 is shown with the 458-CM and 16 line modules installed.

Control Module
The image above shows the connectors on the back of the 458-CM, labeled
RS232, IEEE-488 and Ethernet.
The 458-CM 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 remote control.
When configured for IEEE-488, the 458-CM 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 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-CM.
In order to send RS-232 commands over an Ethernet connection, this feature must be
enabled. Refer to section Enabling Ethernet Connectivity for detailed instructions.

Model 458-CC-16/458-CM (16-Slot Chassis & Control Module) Rev I Page 3
Line Module Series
A maximum of 16 Model 458 Line Modules (sold separately) can be placed into the chassis. Each
458 Line Module can be individually set by the 458-CM. Communications between the 458-CM 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 Ethernet Connections & Commands
Enabling Ethernet Connectivity
RS-232 commands may be sent over an Ethernet connection to control the Model 458-CM. 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.

Model 458-CC-16/458-CM (16-Slot Chassis & Control Module) Rev I Page 15
Before You Begin
Connect the 458-CM and a remote PC to the LAN using Ethernet cables. Please note, when
connecting the Model 458-CM 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.
Administrator access to the remote PC is required.
Installing IP Address Assignment Software
The IP address assignment software (Lantronix Device Installer) 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 458-3SLB. This address allows the assignment software to locate the XPort.
In 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. Save the 4583SL-Ethernet-Install.zip file to the desktop.
2. Extract the files and then navigate to the folder on the desktop.
3. Double-click on the setup_di_x86x64cd_4.3.0.1.exe program file.
4. Select the language.
