NS4024G Mini DSLAM
NexComm Systems' NS4024G is a twenty four port Ethernet-based SHDSL MIni-DSLAM that delivers symmetric data rates up to 2.3Mbps, using a single copper pair and 4.6Mbps, using two copper pairs. This devices is easy to install, 1U compact form factor.

                             
 
  The NS4024G is designed to provide Symmetric DSL Access Solutions for Service Providers. As a small scale Central Office Equipment, this device enables Service Providers to offer highly concentrative Business DSL services.

The NS4024G provides enterprise networking solution with Nexpeed CPE series and delivers all the services of voice, video and data over the same access line.
The NS4024G offers Ethernet-based SHDSL leased line services providing reliability and security of Tag-based VLAN with quaranteed bandwidth is the absolute advantage of NS4024G.
