Would it be possible to be cc'ed the answer ? Handling a MAP can be difficult. I had the pleasure with GSM phase 1&2 where we had to rewrite the MAP messages that were specified as ASN.1 macros so they became ASN.1 information objects.
On top of that - or rather inside that - came the ETSI / ITU specified address fields that were used to specify the use of the many address fields - these were all coded as OCTET STRINGs then. Later came the redefinition of the EXTERNAL type. But the catch is that the proper use of the EXTERNAL type is/was the responsibility of the standardi- sation group responsible- in casu the MAP specifiers. As implementor there is very little you can do. So we had to patch a lot. I guess its still true ? Speaking of European Mobiles - How is the status of the FAN.1 specification / the CSN encoding scheme ? O&M messages for the A and Abis interface. Is CSN still in use ? I had a couple of questions about this from South-East Asia. I had to redirect these to the CSN owners.
