Description

This command allows control of the Call Waiting supplementary service according to 3GPP TS 22.083 [5]. Activation,

deactivation and status query are supported. When querying the status of a network service (<mode>=2) the response

line for 'not active' case (<status>=0) should be returned only if service is not active for any <class>. Parameter

<n> is used to disable/enable the presentation of an unsolicited result code +CCWA:

[,<priority> ]]] to the TE when call waiting service is enabled. Command should be abortable when network is

interrogated.

The interaction of this command with other commands based on other GSM/UMTS supplementary services is described

in the GSM/UMTS standards.

Test command returns values supported as a compound value.
