ITU-T Z.104 (10/2004)

Encoding of SDL data

Encoding of SDL data enables communication of data values between pieces of SDL in an implementation independent way.Data values can be encoded in a text format defined by this Recommendation. Alternatively, when the data is defined in ASN.1, sets of standardized ASN.1 encoding rules can be invoked. The results of encoding can be used internally in the SDL model or to communicate between SDL models or between SDL and other non-SDL elements such as test environments.
