Hardware Installation Manual 5. Cabling the Device
5.3.3 Connecting the FXS Analog Lifeline
The device supports PSTN Fallback (analog Lifeline), whereby it automatically connects a
specific FXS port (the Lifeline extension or phone) to the PSTN / PBX, upon a power
outage or loss of IP network connectivity. This enables the lifeline phone to make and
receive calls to and from the PSTN respectively, during the power outage or loss of IP
network connectivity.
The FXS Lifeline extension or phone connects to FXS Port #1 while the PSTN/PBX
connects to FXO Port #1. When the Lifeline is triggered, the FXS line automatically
connects to the FXO line and calls between these entities can occur.
Notes:
• The FXS Analog Lifeline feature is a customer-ordered item and is only supported on
specific hardware configurations with combined FXS and FXO interfaces. For more
information, contact your AudioCodes sales representative.
• The scenario upon which the Lifeline is activated is configured by the LifeLineType ini
file parameter. For more information, refer to the User's Manual.
