Page 1
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 ban
dwidth 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 Teleby

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.
