Hi,
If you already have a trace of this protocol, take a look at it
with Wireshark. It should decode down to the TCAP layer.
In the SCCP part you should have an SSN number you need
To get ANSI TCAP to decode it by setting preferences.

If you then look at the (ANSI)TCAP part that should give you an idea on how
to proceed...
Regards
Anders

Hi Anders,

Yeah you got right. This runs on top of the ANSI-TCAP layer.I am writing a
separate asn for this file.

I did not import any operations from ANSI-TCAP. I feel there should be an
identifier which TCAP identifies this dissector and its operations( I don't
have that still).Can you please tell me , how does it do it??

In all the .asn files, before the DEFINITIONS , there is a declaration of
the module/PDU ..for example in gsmmap and ansi_map :

MAP-Protocol{ 0 identified-organization (4) etsi (0) mobileDomain (0)
gsm-Network (1) modules (3) map-Protocol (4) version5 (5) }

In the case of TCAP:

DialoguePDUs { ccitt recommendation q 773 modules (2) dialoguePDUs(2)
version1 (1) }

I am not able to write this part for my .asn file. Can you please tell me
the significance of this and how should I go about it??

BR,
Tarani
