Customer Support
Thank you for your purchase of the Telebyte Model 458-2SL Multi-Channel Local
Loop Simulator. This compact unit is extremely easy to use and a perfect fit when
only one or two-channel operation is required. The Model 458-2SL 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 one to two 458
Line Modules, it becomes a two-channel local loop simulator. The built-in Control
Module interfaces with a PC or terminal via IEEE-488 or RS-232 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 rotary encoder.
