Not sure what you mean opcode-initialDP Code ::= local:0 There is no opcode 59 defined in IN-operationcodes.asn Regards Anders

One Answer:


That has nothing to do with the INAP opcodes. This is the ASN1 spec of that field ExtensionField ::= SEQUENCE { type EXTENSION.&id({SupportedExtensions}), -- shall identify the value of an EXTENSION type criticality CriticalityType DEFAULT ignore, value [1] EXTENSION.&ExtensionType({SupportedExtensions}{@type}) } So the extension is of the local type 59, as this seems to be a Simens INAP trace that's probably a Simens proprietary extension.

Probably not without Simens specification of the extension.
