Welcome to 3G Telco Tools

This site is planned to contain the following utilities. These utilities should prove useful to people working in telco environments, and to my knowledge there are no other free tools available to do these things.

The contents of each section are progressively more involved and so will take longer to develop and therefore appear. Encouragement helps.

3GPP CDR file decoder - decode CS, PS and IMS CDR files
3GPP CDR file editor
DIAMETER/DCCA test server - test your DCCA device against a test server
