   service.

   (2) Wideband and Exchange Trunk C&WF—Category 2—This category includes
   all wideband, including Exchange Line Wideband and C&WF between local
   central offices and Wideband facilities. It also includes C&WF between
   central offices or other switching points used by any common carrier
   for interlocal trunks wholly within an exchange or metropolitan service
   area, interlocal trunks with one or both terminals outside a
   metropolitan service area carrying some exchange traffic, toll
   connecting trunks, tandem trunks principally carrying exchange traffic,
   the exchange trunk portion of WATS access lines, the exchange trunk
   portion of private line local channels, and the exchange trunk portion
   of circuits between control terminals and radio stations providing very
   high frequency maritime service or urban or highway mobile service.

   (3) The procedures for apportioning the cost of exchange cable and wire
   facilites among the operations are set forth in § §  36.154 and 36.155.

   coastal harbor service, interlocal trunks between offices in the
   different exchange or metropolitan service areas carrying only message
