10.15 PSTN Line (“L” models only)
With PSTN line you can make and receive regular PSTN phone calls. Use a prefix number to
make a regular call. When the device does not have power, you can make regular calls without
dialing a prefix number.

When the ZyXEL Device does not have power, the phone(s) connected to the
PHONE port(s) can still be used for making PSTN calls. Only one phone can
be in use at a time.
You can also use the PSTN Line screen to specify phone numbers that should always use the
regular phone service (without having to dial a prefix number). Do this for emergency
numbers (like those for contacting police, fire or emergency medical services).
