Enclosure Space Reclamation ABC´s

Current telecommunications enclosures typically include a DC power system and battery backup that consumes a significant portion of the available real estate. When new equipment is added to provide new or upgraded services or to serve additional subscribers, there are dual stresses of increased power and back up demands as well as conflicting needs for more space within the enclosure. New battery technologies (lithium metal polymer) don´t require the conditioned environment needed for VRLA and thus offer an opportunity to relocate the battery backup out of the main enclosure. The paper will discuss an external wall mounted enclosure (an alternative battery cabinet) applicable for concrete walk-in enclosures or huts that can house the LMP batteries. The specifics of this case study will be presented in detail including the economics of space reclamation on this scale. The several advantages of the ABC approach will be submitted for obtaining added revenue generating space in existing enclosures
