BUILDING Backbone...................Coding.......Print PDF

BC	Bonding Conductor –  A conductor used as a path for foreign electrical currents to pass to earth ground.
BCA	Backbone Cable – Large Fiber/Copper telecommunications type cables used to transport electronic circuits between buildings and TC’s.
EC	Equipment Bonding Conductor –  A copper conductor used to bond RK’s or PROT’s to the TBG or TMGB.
ER	Equipment Room – The room where electronic circuits originate or are modified, the room containing equipment racks, trays and wall fields.
GP	Grounding Pathway – A supporting WW for bonding conductors.
HC	Horizontal Cable (i.e. Distribution Cable) – Fiber/Copper telecommunications media made up of grouped strands or wire enclosed within a sheath, used to transport electronic circuits from TC’s to the WS.
HP	Horizontal Pathway - A conduit or cable tray(plastic or metal), necessary to support Horizontal Fiber/Copper cables and wire.
PC	Patch Cord –  A pair of Fibers made up to a specific length for patching circuits from one PP to another PP.
PP	Patch Panel – A frame for mounting circuit connectors
PROT	Protection Hardware – A device used to isolate foreign electrical current.
PT	Patching Tray – A Metal or Plastic WW .
RK	Rack – A frame for mounting Electronics and PP’s.
TBB	Telecommunications Bonding Backbone - A large bonding conductor extending from the TMGB, out to building TGB’s.
TC	Telecommunications Closet - The room where electronic circuits are modified, the room containing equipment racks, trays and wall fields, before connecting circuits to the WS.
TGB	Telecommunication Grounding Busbar –  A connection base used for bonding Telecommunications EC.
TIC	Tie Cable – A group of paired wires enclosed within a sheath.
TMGB	Telecommunication Main Grounding Busbar – A large connection base at the building entrance bonded to the Grounding .Electrode System on the inbound neutral side of the electrical power system.
TP	Transition Point - See Distribution
WC	Wire Closet – A closet or cabinet containing a WF for extending Voice Grade circuits to WS's located outside the data limits of any ER or TC.
WF	Wall Field – A surface used to mount TH.
WW	Wireway –  A conduit or cable tray(plastic or metal), necessary to support Fiber/Copper cables and wire.
