What is NEBS?

NEBS stands for "Network Equipment-Building System"

NEBS describes the environment of a typical Regional Bell Operating Company (RBOC) Central Office (CO). This description includes spatial and environmental criteria. Typical equipment line-ups are described including the environment they're exposed to.

NEBS was developed by Bell Labs back in the 1970s to standardize equipment that would eventually be installed in a CO.  The intent was to make it easier for a vendor to design equipment compatible with a typical RBOC CO.  This would result in lower development costs and ease the equipment's introduction into the network.
