Description£º
Loop Telecom's Loop-U3500 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-U3500 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. |
