Qt Cell Module

The Qt Cell module offers support for modem based telephony backend. This module is based on Base module.

The following configure line can be used to build the Base and Cell module:

    ./configure -modules cell -device xyz

The -modem option is equivalent to the -modules cell option. This module implies the Telephony module.

Feature description

This module provides a modem based back-end for the Qt Extended Telephony API. The actual modem interface can be AT based or any other form of programming interface.

Feature	Details
Modem integration	This module uses the Qt Extended Telephony API and provides a back-end implementation for modems. In order to increase the reusability the modem integration uses a plug-in mechanism. The following two types of plug-ins are supported: The Phone vendor plug-in caters for differences among the various 3GPP AT command implementations supported by various modems. The GSM modem integration guide explains how phone vendor plug-ins work and how new plug-ins can be created. The Multiplexer plug-in can be used to replace the default GSM 07.10 mulitplexing provided by this module. The Writing a Multiplexer Plug-in tutorial gives a brief introduction into this feature and demonstrates how a new plug-in can be created.
Call Forwarding	This application allows the user to configure forwarding rules for Data, Fax and Voice calls.
Call Networks	This application allows the user to configure the preferred network operator selection process.
Call Options	This application allows the user to configure the following parameters: Call Barring (selectively block calls to/from device) Call Waiting Caller ID Cell Broadcasting Fixed Dialing (restrict outgoing calls to white-listed numbers) Service numbers (voice mail and SMS service center) Call volume
Other features	The following minor features are included in this module: GPRS/3G connection monitor SIM Toolkit support GCF compliant GSM dial filter SIM based call history support

Software components

The Cell module includes the following software components:
