Detailed Product Description

GT-DSM-48 offers lower port count DSLAM available in the market place. It provides the least initial investment solution for Service Provider who want to start providing Broadband service in a low subscriber density location. The unit features maximum downstream rate up to 24 Mbps and maximum reach distance over 6.5 Km. It is most suitable for use on existing copper twisted pair telephone lines to provide high speed Internet access.

This 48-port interface module is compliant with ITU G.992.5, G.992.3, G.992.1, and features the Link Status LED indica- tors in front panel. When LED turns steady green that means the line connection is valid and operational. Our company ’s ADSL2+ technology is also backwards compatible with early version of ADSL. This ADSL2+ technology is an enhanced version of the ADSL technology which provides cross-talk free deployment. The ADSL2+ DSLAM is ideal solution for Triple-play requirements.
