product overview

The Model 458-LM-E1-30-04+ Multi-Standard Local Loop Simulator is the ideal solution for ADSL, ADSL2, ADSL2+, G.shdsl and VDSL2 chip/modem/DSLAM testing. This single-pair loop simulator can simulate either 0.4mm PE for ADSL, ADSL2, ADSL2+ and VDSL2 or PE04 for G.shdsl. Optional noise sources may be ordered that add in AWGN on the CO and CPE side that may be independently controlled.

This versatile 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). In addition, the user-friendly 458 Universal GUI may be used for remote control. 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.
