Cartes d'interface AC double 4W

The Data Analog AC Dual 4-wire interface card is based on the FXO design, however it does not provide signalling and battery feed. The interface is 600 ohm dry, or may have a sealing current less than 4mA. The CO and Station side cards have the same interface, however the LEDs and powering mode are different.

Applications:

• Dedicated line modems
• Supervisory control and data acquisition (SCADA) systems
• Tone relay control systems
• Analog carrier systems
• Any other equipment using tone related signalling
