DTU

Loop-U 3500/ Loop-U 500 DTU SERIES

STAND-ALONE

Description

Loop Telecom's Loop-U 3500 DTU series provides an economic solution to extend DTE interfaces over 2 copper wires up to 5.5 Km. This series uses adaptive echo cancellation to provide high quality 128 Kbps digital data transport. The Loop-U 3500 DTU series provides one DTE port, operating at synchronous rates from 1.2 to 128 Kbps and asynchronous rates to 19.2 Kbps. Co-direction is supported. This allows users to interconnect LANs and WANs, CAM video conference, mainframe hosts, and others.

Loop-U 3500 DTU series supports configuration and diagnostics from front panel LCD display and keypads or RS232 console port. This allows users to execute diagnostics and fault isolation.

This product series also provides 9 LEDs for both line side and DTE side status indicators
