H.323 User's Manual 3. Installing the Mediant 1000
Version 5.0 41 December 2006
The Lifeline provides a wired analog POTS phone connection to any PSTN or PBX FXS
port when there is no power, or when the network connection fails. You can therefore, use
the Lifeline phone even when the Mediant 1000 is not powered on or not connected to the
network.
The Lifeline splitter connects pins 1 and 4 to another source of an FXS port, and pins 2 and
3 to the POTS phone (refer to the Lifeline pinout in Figure 3-7 on page 41).
The use of the Lifeline on network failure can be disabled using the LifeLineType ini file
parameter (described in Table 6-2 on page 217).
