Use of Advice of Charge supplementary service command enables the
subscriber to get information about the cost of calls. With <mode>=0, the
execute command returns the current call meter value from the ME. The
command also includes the possibility to enable an unsolicited event
reporting of the CCM information. The unsolicited result code +CCCM: <ccm>
is sent when the CCM value changes, but no more than every 10 seconds.
Deactivation of the unsolicited event reporting is made with the same
command.
Read command indicates whether the unsolicited reporting is activated or
not. Read command is available when the unsolicited result code is
supported.
It is recommended (although optional) that the test command return the
supported mode values.
