Analog Hardware Configuration

You must configure your analog hardware according to the needs of your system as part of your initial CSG
configuration. The Configure Hardware page gives you the ability to configure both your FXS and FXO
ports, as well as your Tone Region, operation mode, message waiting indicator mode (MWI), etc. The number
of FXS and FXO ports available for configuration will depend on the CSG model you purchased. Click the
Configure Hardware tab to configure your analog hardware.
The Configure Hardware tab will not be available if you ordered a VoIP only model.
FIG. 12 displays the Configure Hardware page.

FXS and FXO ports provide the ability to receive and send calls through the traditional telephone network, or
POTS (Plain Old Telephone System). FXS modules provide both dial tone and ringing voltage to an analog
phone. FXO modules accept dial tone and provide an interface to the traditional phone lines. You plug a
telephone line into an FXO port, and an analog telphone into an FXS port.
On this page you can specify the signalling type for your FXS and FXO ports. You have two choices; either
Kewl Start or Loop Start. The Loop Start method uses a short to request a dial tone. All North American home
phone lines use loop start signalling. Kewl Start is the same as Loop Start, but is better able to detect
disconnects. Select either Kewl Start or Loop Start for each FXS and FXO module. Kewl Start is the default
and is preferred for analog circuits in the CSG.
Ground Start signalling is not supported.
You also need to select a tone region, which defines the set of tones (dial tones, ringing tone, busy tone, etc)
used in your region. Select your country, or the nearest neighboring country, from the Tone Region drop-down
list. The default setting is North America (United States/Canada).
