initial commit of Erlang SCCP implementation
...
This code is my humble attempt to implement the most important
parts of the Q.71x specifcations in Erlang. The process tree
is trying to model the SCCP reference model as closely as psosible.
The SCRC and SCOC entities are implemented as OTP gen_fsm behavior.
SCLC is not implemented as separate state machine to reduce the number
of processes and message passing between them
SCMC is not implemented at all.
Each MTP (or other transport link) has one SCRC instance and as many
SCOC instances as there are connection-oriented SCCP sessions on this link.
There is no support for Global Title Translation (GTT) as of now.
