product overview
The Model 458-LM-E8-2 is a component of our G.SHDSL production testing solution. This high-density 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-E8-2 to be combined with other line modules for a wide variety of test configurations.
