The Model 458-LM-E1-30-04 Multi-Standard Local Loop Simulator is the ideal solution for ADSL, ADSL2, ADSL2+, and VDSL2 chip/modem/DSLAM testing out to 9,000 meters in very small increments. Optional noise modules may be ordered that add in AWGN on the CO and/or CPE side, depending on the configuration purchased. The ultimate configuration allows for common or independent noise levels on both sides.
This powerful local loop simulator is plugged into our Model 458-3SLB (3-Slot) or 458-CC-16 (16 Slot) chassis where settings are controlled by a convenient keypad located on the front, RS-232, Ethernet or IEEE-488(GPIB). The modular design of Telebyte's products allows the 458-LM-E1-30-04 to be combined with other line modules for a wide variety of test configurations.
