   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.
