BSC3i mechanical design
Welded frame structure designed on IEC, EN, ETSI, UL andTelcordia recommendations with advanced features in termsof safety, protection against interference, stability anddurability
Easy transportability and suitability for installations withnormal room height as well as with completed internal
cabling Due to the simple mechanical structure with relatively few
components, the equipment cabinets are easy to assembleand disassemble when necessary
The BSC3i includes forced cooling system to ensureoptimum ambient temperature for its functional units
