电话拨号演示系统（需硬件板卡支持）

/**********************************************************
  this project is mainly to show how to dial out of trunk 
with TC-30E1(60E1) and TC-08A board,your can take it as a
simple switch(only export).
  Before running this demo,your should make sure that your
computer has pluged with the two board and the TC-30E1(60E1)
board is connected with another TC-30E1(60E1) board in another
computer that running an application(such as demo.exe).
