Notes
Although already present in the PABX, place external protections against overvoltage
or atmospheric discharge on the external lines, on the electric mains and on the extension
lines, if partially located outside the building.
The correct operation of the telephone installation is guaranteed when using homolo-
gated telephones.
If the general call function is required, connect facsimiles, modems and answering
machines to the terminals of the last extension (DER45 for FT105P; DER48 for FT208P)
because they do not receive the call signal.
