WISI COMPACT HEADEND
Compact, strong and extremely flexible
The WISI COMPACT HEADEND System OH is pre-equipped
both for wall installation and for installation in a 19“ rack. The
material required for installation is already furnished with the
basic unit so that a simple installation and configuration of the
system is guaranteed.
WISI COMPACT HEADEND features a new economy of space
for professional headends. Despite the growing number of
channels the foot print in many locations becomes a problem.
Not so with the headend with the highest functional density in
our industry.
