Content Comparison

There are two types of analog lines used in Switchvox:

FXO:

• receives power from the telco

• Modules are colored red

• generally comes from telco and carries calls to the PBX

FXS:

• provides power to analog devices

• Modules are colored green

• generally runs from the PBX to an analog phone or fax machine

Basic troubleshooting:

On FXO lines check under Server -> Diagnostics -> Connection Status to see the channel status of any FXO lines. If they show red alarm either the lines are not connected securely or power is not being provided from the telco. To check for port or module issues you can connect one of the lines to an analog phone and check for dial tone to verify power.
