The FOXMAN-UN NP does not replace FOXMAN-UN BP but operates as an important add-on to the package, providing enhanced features and functionality. The FOXMAN-UN BP enables management of FOX51x and FOX61x networks from a physical point of view. The FOXMAN-UN NP operates on top of the FOXMAN-UN BP to focus on end-to-end TDM connections (circuits) that the physical network contains.
