h1. OsmoSTP 

 The Osmocom Signal Transfer Point is    a SS7 Transfer Point implementing MTP routing as well as SIGTRAN SG (Signaling Gateway) functionality. 

 The program is currently part of the [[libosmo-sccp:]] git repository, as it is basically just a small main loop + VTY interface wrapped around the libosmo-sigtran code (which in turn implements connectionless + connection-oriented SCCP, SUA and M3UA in both SG and ASP roles). code. 

 h2. SIGTRAN protocol support 

 OsmoSTP supports all transport protocols implemented in [[libosmo-sigtran:]].    At time of this writing (October 2017), this includes: 
 * SCTP + M3UA + SCCP 
 * SCTP + SUA 
 * IPA + SCCP (experimental 

 We're looking for contributions/funding to add more protocols like M2UA, M2PA 

 h3. traffic mode support 

 OsmoSTP currently only implements _override_ and doesn't implement the _load-share_ or _broadcast_ traffic modes. Contributions in whatever form are welcome.

 h2. Manual 

 The OsmoSTP user manual is still work in progress.   

 * "osmostp-usermanual.pdf":http://ftp.osmocom.org/docs/latest/osmostp-usermanual.pdf 
 * "osmostp-vty-reference.pdf":http://ftp.osmocom.org/docs/latest/osmostp-vty-reference.pdf has not been written yet.    Once written, it will be released at http://ftp.osmocom.org/docs/latest/ where the other Osmocom cellular network manuals are published.    If you'd like to help us by donating time or funds towards the creation of a manual, let us know.
