  Yes, I wasn't clear. If a large and increasing number of users (POTS or ISDN)
  have their lines in use for significantly longer durations (1+ hour) than the
  normal 2 - 4
  minutes of traditional voice calls. Then there are many more lines (and thus
  switching/trunking capacity) being utilized a the same time. The conventional
  statistical "muxing" of the phone network capacity is overloaded and the phone
  company must ether significantly upgrade their switching/trunking OR bypass
  the long duration datatraffic off the switched voice network and onto a high
  capacity dedicated backbone like infrastructure.
