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 guaranteed bandwidth is the absolute advantage
of NS4024G.
