Which AC Impedance Modes Do FXS Interfaces on a 4FXS1FXO Interface Card Support?
Solution
FXS interfaces on a 4FXS1FXO interface card support the following AC impedance modes:
  • 0 - CNOF (200+680||100nf)
  • 1 - CNUSER (200+560||100nf)
  • 2 - 600 ohm interface (default)
  • 3 – RUSSIA (150+510||47nf)
  • 4-(220+820||115nf)
  • 5-(220+820||120nf)
  • 6 - 900 ohm interface
  • 7 - BRAZIL (800||50nF)
  • 8-BT0 (Zin=87+1052||228nF+229||284nF,Zload=93+615||471nF+179||495nF+244||32nF)
