  • The current on the CO side can be set to 2 mA or 20 mA using a jumper setting
  • The battery feed on the Station side can be set to -100 Vdc (positive on Tip), -50 Vdc (positive on Tip), -130 Vdc (positive on Tip) or -65 Vdc (positive on Tip). The battery can be grounded or set to a floating condition
  • The card is powered from either the -24 Vdc or -48 Vdc output of a Teleline Isolator plug-in power supply
