Harald Welte e16d8145c1 add 'tcap_helper' module for unit testing or shell use
This module permits simple generation of common TCAP messages.

Harald Welte 10adfb5933 make sure tcap_asn module contains TR/dialogue portion, too 2011-12-10 21:39:43 +01:00
Harald Welte 6cc415222f Add separate TCAP decoder that is not linked to MAP
this way we can parse only the TCAP layer into dialogue portion
and component portion, but without actually parsing those.

Harald Welte 21c6b94271 MAP: Fix-up after asn1ct automatic 1990->1994 EXTERNAL conversion
So what the Erlang asn1ct does is:  Decode the incoming EXTERNAL type,
convert it to the 1994 format and hand it to the user program.

The encoder is opposite:  Take what the user supplies (in our case 1994)
and then transform it to 1990 before handing it to the actual encoder function.

The only problem is: The 1994 format does only support OCTET STRING as actual
embedded data type, whereas the 1990 format can also indicate
'singla-asn1-type', i.e. a constructed type.

So since that information is already lost before we ever get the record from
the Erlang asn1 decoder, it will be re-encoded as OCTET STRING :(

Until this is fixed in the asn1ct/asn1rt code, we have to use this workaround...

Harald Welte a864e9d436 Add manually generated MAP-Contracts package
This is a non-standard MAP package creating ROSE CONTRACT information object
class instances which will later be used by TCAP APPLICATION-CONTEXT
information object classes that in turn will formally associate the
OPERATION-PACKAGES with the application context names.

Harald Welte da91cb537f Add manually-created ASN.1 file with MAP Operation Packages
It sems both ETSI and 3GPP violate their own 09.02 / 29.002 specification
by not shipping the MAP-OperationPackages module the specification

Harald Welte d08ea8d673 use asn1ct/asn1rc in 'ber list' mode, as 'ber binary' mode has bugs
