2012-04-16add compatibility clause for Erlang Public LicenseHarald Welte1-0/+14
This is required to make sure that even if somebody thinks the erlang OTP libraries and my code form a derivative work, there will be no licensing conflict.
2012-01-24SCCP codec: fix parsing of CC message option partHarald Welte1-2/+3
2012-01-23sccp codec: correctly parse and encode CR message variable/optional partHarald Welte1-17/+84
2012-01-23sccp codec: ensure correct encoding of 'undefined' point codeHarald Welte1-6/+3
2012-01-18SCCP Codec: don't include 'encoding' in sccp_addr{}Harald Welte1-3/+3
The Encoding parameter really only tells us about the odd/even number of digits, and that information is already present as the list of digits in the decoded address.

2011-10-12sccp_codec: SCCP point codes are little-endian !Harald Welte1-2/+2
we parsed and generated them as big-endian so far, which is wrong.

2010-12-19initial commit of Erlang SCCP implementationHarald Welte1-0/+183
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.
