48 ports IP DSLAM Switch

DSLAM5048 is a special pizza box designed for outdoor application with the physical depth about 320mm and the operating temperature up to 60°C . It terminates all the ATM circuits and converts traffic directly to deliver the most popular broadband IP services.



DSLAM5048 offers better bandwidth utilization, ease of use, as well as the low-cost advantage and provides the least initial investment solution for internet service providers who want to start providing broadband service in a low subscriber density location.

DSLAM5048 is compliant with ITU G.992.5, G.992.3,G.992.1, and backwards compatible with early version of ADSL.Its maximum downstream/upstream rate is up to 24/1.2Mbps and maximum reach distance is over 6Km. It is most suitable to provide high speed Internet access on existing copper twisted pair telephone lines.

With the highly compact (1U height) and temperature-hardened design, simple installation and easy adaptation to local POTS/ISDN splitter requirements,DSLAM5048 is an ideal solution for Triple-play requirements deployed in indoor and outdoor enclosures.
