GXE502X User Manual 7/9/2008

The FXO and FXS port/line electric specification parameters and settings can be configured in this area as well. All of these will allow users of the GXE502X to make calls anywhere through multiple trunk types.

- Internal PSTN Trunk Line Configuration (via FXO ports)

The Internal PSTN Trunk Line Configuraiton page lets your configure the FXO ports on the back of the GXE502X to make and receive calls to and from the PSTN.

Compatibility with different PSTN lines can be achieved by adjusting the related parameters on the Internal PSTN Trunk Line Configuration page. The default settings should function in most cases. Correct technical data must be obtained from local Telco carriers and implemented on the GXE502X before the lines will function. This data depends on the regional PSTN line characteristics.

FXO Termination: This section lets you specify the line disconnect signaling and impedance.

Enable Current Disconnect: Default is Yes.
