text: Network operating costs were $32.5 million, an increase of $5.8 million or 21.5%. Line and switching costs were $9.7 
  million, an increase of $2.6 million or 37.4%, due principally to the impact of the expanded PCS network. Travel 
  expense, generated by the Company’s PCS subscribers’ use of minutes on other providers’ portions of the Sprint 
  wireless network, was $10.7 million, an increase of $0.9 million or 8.4%. The increase in customer travel usage more 
  than offset the travel rate explained above in travel revenue. Plant specific costs were $9.6 million, which include the 
  operation, and maintenance of the networks increased $2.3 million or 30.7%. Tower, building, and land rentals, as well 
  as PCS equipment maintenance, were major contributors to the increase in plant specific expenses. Other network 
  costs such as power, network administration, and engineering, were $2.7 million, the same as in 2001.
