10.15 PSTN Line (“L” models only)

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).
