COMI cell timeout
Select the number of seconds you want the TRS process to wait for the
transaction to complete by moving the slider under “Timeout”. There is an
available range from 1 to 75 seconds. This indicates the maximum time for
the COMI cell to start the transaction and send the necessary input buffers,
and for the COMO cell to receive the output buffers. The TRS process rejects
the transaction and sends back a timeout if the action is not performed within
the time allotted.
Note: The application will take the timeout branch of the COMI cell if a
timeout occurs.
Note: There is an inherent 5 second transaction time for each
sleep-descriptor input. The total value of the sleep-descriptor and the
inherent time must not exceed the time out value. For example, with 10
buffers, the inherent wait time is a minimum of 50 seconds. Therefore, the
time out value should be greater than 50 seconds.
COMI cell buffer count
You do not need to enter a value in this field as IVR 2.0/I automatically
calculates the number of buffers when you click the “Apply” button.
COMI cell input buffers
Enter the names of the input buffers containing the information to pass to the
TRS process. The input buffer shown in Figure 4-3 is ACCOUNTNUMBER,
without any quotes. In this example, you must program your application to
place the customer’s account number in the ACCOUNTNUMBER buffer
before the COMI cell is executed.
In this example, ACCOUNTNUMBER is a user-defined buffer; you can use
any name for your applications, or you can use system buffers.
Note: You must enter the input buffers in the same order the host computer
uses them.
If you need to use more than 10 input buffers in your application, make sure
you select “Yes” for “More Input?”, then string COMI cells together until you
have enough input buffers. Connect each additional COMI cell to the
previous one’s “SUCCESS” branch.
