The Model
458-LM-A1-30 Multi-Standard Local Loop Simulator is the ideal
solution for ADSL, ADSL2, ADSL2+, and VDSL2 chip/modem/DSLAM testing
out to 24,000 feet 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-A1-30 to be combined with other line modules for a wide
variety of test configurations.
