The FXO interface card is a Telco/PTT interface that acts like a standard telephone set (a
two-wire telephone in a loop start circuit). This interface card:
• Provides a Subscriber Line connection to a Central Office or the station side of an
analog PBX.
• Detects ring voltage, closes the loop during off-hook, and opens the loop in an
on-hook condition.
• Generates pulse dial or DTMF tones.
• Dual port interface with 2 RJ-11 female connectors for the dual FXO interface
card.
