Connecting the FXS Analog Lifeline Phone
The device supports Analog Lifeline. If the device loses power, for example, due to a power outage or the unplugging of its power cable, it automatically routes calls from a POTS telephone ("lifeline" phone), connected to an FXS port, to the PSTN (instead of the IP network).
| ● | Analog Lifeline is supported only on FXS modules. |
| ● | An analog Lifeline can be setup for each FXS module installed in the chassis. |
The analog Lifeline is provided only by Port I on an FXS module. This port connects to the POTS phone and the PSTN or PBX, using a splitter cable. The splitter cable connects pins 1 and 4 to another source of an FXS port, and pins 2 and 3 to the POTS phone, as shown in the following figure:
Cabling specifications:
