Test Set calculates the contents of the Parity field using the coding algorithms specified in the industry standard for the selected system that is the system specified in the System Type field on the CALL CONTROL screen By definition the Test Set must meet the timing requirements of the industry standard for the selected system Therefore depending upon the state of the Call Processing Subsystem i e Active Register Page Access or Connect and the frequency with which a particular call processing protocol uses a particular message it may not be possible to modify the contents of more than one field ina message before it is sent to the mobile station For example in the AMPS system the system parameter overhead message must be sent every 0 8 0 3 seconds on the forward control channel Given this timing requirement it is highly unlikely that while in the active state a user could modify more than one field before the message was sent to the mobile station There is no functionality in the Test Set to allow an entire message to be modified and then inserted into a messaging protocol at a specific location at a specific time This functionality requires a protocol analyzer When in the Bits mode the Test Set provides the messaging protocol for the user that is for a desired call processing function the correct message s will be sent at the correct time s according to the standard It is the responsibility of the user to generat
