ANSI National Operations The ANSI Operation Codes are divided into an Operation Family and an Operation Specifier. Each specifier belongs to a family and must be interpreted in the context of that family | ANSI National Operations The ANSI Operation Codes are divided into an Operation Family and an Operation Specifier. Each specifier belongs to a family and must be interpreted in the context of that family. ANSI defines a base set of national operation codes and parameters. At the time of this writing these codes and parameters continue to be used for IN services such as toll-free and LNP however specifications now exist to provide the AIN-equivalent functionality for these services. Table 10-21 lists the operation families with their associated specifiers and definitions. Table 10-20. ANSI Operation Codes Operation Family Operation Specifier Binary Value Definition Parameter 00000001 Indicates an operation to be performed on a parameter. Provide Value 00000001 Request to provide a value for this parameter. Set Value 00000010 Request to set the parameter s value. Charging 00000010 Charging operations are related to how calls are billed. Bill Call 00000001 Indicates that a billing record should be made for this call. Provide Instructions 00000011 Requests instructions according to the service script which is the application logic that is used to implement a service and handle the incoming and outgoing TCAP message information. Start 00000001 Initiates the interpretation of the service script. Assist 00000010 Used to request instructions when assisting with a service request. This situation arises when a node does not have the necessary resources such as an announcement or IVR system to connect to the user and another node that has the proper resources is connected to assist with the transaction Connection Control 00000100 Used for specifying the handling of call connections. Connect 00000001 Indicates that a connection is to be made using the given called address. Temporary Connect 00000010 A connection is to be made using the given called address and will be followed by a Forward Disconnect. The Forward Disconnect releases the connection to the temporary resource. .
