The SCCP code is in production and in use in a real GSM network. The TCAP/MAP
code was written to be able to do a Location Updating (or equivalent) in
OpenBSC SGSN/GGSN. Harald can comment best on this state but from what I
remember the TCAP code should be fully complete, the MAP code is not.

For both TCAP/MAP the lack of a good ASN1 C library is a bit of a show stopper.
