product overview

The Model 458-LM-A1-30-TR114 Local Loop Simulator for TR-114 is the ideal solution for simulating test loops as defined in TR-114 and includes a Bridged Tap. In addition, it is also suitable for ADSL, ADSL2, ADSL2+, and VDSL2 chip/modem/DSLAM testing of straight loops out to 24,000 feet in very small increments.

This versatile local loop simulator is plugged into our Model 458-3SLx (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-TR114 to be combined with other line modules for a wide variety of test configurations.
