Description

ARL-2M is a point-to-point 2 Mbit/s radio transmission system, with ranges of about a dozen km. The system, which does not require licensing, due to the operation in the ISM (Industrial, Scientific and Medical) 2.4 GHz band, uses advanced spread spectrum techniques, resulting in excellent performance and information security.

ARL-2M system is available in two configurations, 6U  (LIU2000RF) line interface unit for integration in MUX2000 (2 Mbit/s access multiplexer), and stand-alone, desktop unit or 19" 1U rack unit for simple installation in telecommunications cabinet.

When integrated in the MUX2000, the line interface card is configurated through InLoCo_2000, or remotely through Management System INOSSV2. The stand-alone versions have local configuration SW and allows remote management.
