ASN.1 Protocol Specification

ASN.1 Protocol Specification

When you create a Data Processor transformation for the ASN.1 library, you select an ASN.1 protocol specification for the transformation. The specification defines the expected input structure.
An ASN.1 protocol specification is a schema for an ASN.1 data structure. The specification is a text file with an
*.asn
extension.
The protocol specification defines the expected structure for input data. The following lines from a protocol specification define a nested data structure:
MobileTerminatedCall ::= [APPLICATION 10] SEQUENCE { basicCallInformation MtBasicCallInformation OPTIONAL, locationInformation LocationInformation OPTIONAL, equipmentInformation EquipmentInformation OPTIONAL, basicServiceUsedList BasicServiceUsedList OPTIONAL, supplServiceUsedList SupplServiceUsedList OPTIONAL, camelServiceUsed CamelServiceUsed OPTIONAL, valueAddedServiceUsedList ValueAddedServiceUsedList OPTIONAL, dualServiceRequested DualServiceCode OPTIONAL, operatorSpecInformation OperatorSpecInfoList OPTIONAL } ... ChargeableSubscriber ::= CHOICE { simChargeableSubscriber SimChargeableSubscriber, minChargeableSubscriber MinChargeableSubscriber } ... SimChargeableSubscriber ::= [APPLICATION 199] SEQUENCE { imsi Imsi OPTIONAL, msisdn Msisdn OPTIONAL }
The entire structure is a protocol data unit (PDU). A single protocol specification can define multiple PDUs. A protocol specification defines multiple types of data structures with different top-level elements.
