New 2FXS / 2FXO survival module

The 2FXS / 2FXO module was designed to be used exclusively with the UMG line.
With this module in use, in case of a power failure, the module allows passive switching between analogue public lines (FXO) and analogous extensions (FXS), thus working in survival mode, with 2 extensions operating normally, directly connected in the 2 public lines.
