PSTN Line
This chapter applies to “L” models only. Use this screen to set up the PSTN line used to make 
regular phone calls. These phone calls do not use the Internet. 
12.1  PSTN Line Overview
With the Public Switched Telephone Network (PSTN) line, you can make and receive regular 
phone calls. Use a prefix number to make a regular call. When the ZyXEL Device does not 
have power, you can make regular calls without dialing a prefix number. 
You can also 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).
"
When the ZyXEL Device does not have power, only the phone connected to the 
PHONE 1 port can be used for making calls. Ensure you know which phone this 
is, so that in case of emergency you can make outgoing calls.
