Call Processing State Synchronization

Description

Connected/Idle Query
This query will determine if a call is connected or disconnected by returning an integer value. The value
indicates if the call state is idle or connected, not if any call state change has occurred.
Query returns one of the following:
• 0 = idle
• 1 = connected
If the call is in the setup request, proceeding, alerting, or disconnecting state, this command will not return a
value until the call status proceeds to either connected or idle.
OUTPUT 714;"CALL:CONNECTED:STATE?"
Example 5. Base Station Originated Call - Using the Connected/Idle Query
The following example illustrates the use of the connected/idle query for a base station originated call. This
code originates a call, then waits for the connected/idle query to return a result.
Note that this code does not include the CALL:CONNECTED:TIME (timeout timer) or the
CALL:CONNECTED:ARM (change detector arm) commands. These commands are unnecessary since the
change detector is armed automatically by the CALL:ORIGINATE command, and the timeout timer value is
never applicable since a base station originated call guarantees a state change.
10 OUTPUT 714;"CALL:ORIGINATE" ! Begin the BS originated call.
20 OUTPUT 714;"CALL:CONNECTED:STATE?" ! The connect/idle query.
30 ENTER 714;Call_connected ! Program will hang here until state

Call State Change Detector
This feature provides a method for holding off the
processing states is detected. Arming the call state change detector is useful only for mobile station originated
calls or disconnects only. It is armed automatically when call processing functions originating from the test set
are requested.
The call state change detector becomes disarmed when any of the following conditions have been met:
• the call processing state has changed to either connected or idle
! change or protocol timer expires.
