Today I have released my SS7/C7 point code converter PHP class as open source software on launchpad. The code is released under the GPLv3 license. The main purpose of the class is to convert Signaling Point Codes from and to the following formats:

• decimal
• binary
• hexadecimal
• ITU (3-8-3)
• ILR (Institut Luxembourgois de Régulation) (7-4-3, as used in Luxembourg)
• BNA (Bundes Netz Agentur) (4-3-4-3, as used in Germany)

The code is published at: http://launchpad.net/ss7-pointcodeconverter/

UPDATE: I have published the very simple example included with the source code at http://marc.storck.lu/opensource/SS7PCC/example.php.
