<p>A gateway computer is connected to a wireless station switch which receives and sends transaction processing data between remote terminals and a transaction processing host. The gateway interprets an exception code in the data packet received from the terminals to determine whether data is to be forwarded or whether a predetermined circuit management activity is to be carried out by the gateway for the purposes of call request, call accepting, acknowledging, negative acknowledging, call clear requesting, call clear confirming or call reset confirming. The terminals make use of the exception code to make it easier for the gateway to either pass on data or carry out the predetermined circuit management activity while reducing both the amount of interpretation and processing required by the gateway and reducing over-the-air traffic between the terminals and the wireless station.</p> |
