This can be installed from:git@github.com:RangeNetworks/liba53.gitStarting with release 4, OpenBTS requires zeromq (zmq).  This can be installed by running:$ sudo ./NodeManager/install_libzmq.shFor additional information, refer tohttp://openbts.org.These are the directories:AsteriskConfigAsterisk configuration files for use with OpenBTS.CommonLibCommon-use libraries, mostly C++ wrappers for basic facilities.ControlControl-layer functions for the protocols of GSM 04.08 and SIP.GSMThe GSM stack.RRLPRadio Resource Location ProtocolSIPComponents of the SIP state machines ued by the control layer.SMSThe SMS stack.SRThe subscriber registry.TRXManagerThe interface between the GSM stack and the radio.TransceiverThe software transceiver and specific installation tests.appsOpenBTS application binaries.docProject documentation.testsTest fixtures for subsets of OpenBTS components.smqueueRFC-3428 store-and-forward server for SMSBy default, OpenBTS assumes the following UDP port assignments:5060 -- Asterisk SIP interface5061 -- local SIP softphone5062 -- OpenBTS SIP interface5063 -- smqueue SIP interface5064 -- subscriber registry SIP interface5700-range -- OpenBTS-transceiver interfaceThese can be controlled in the CONFIG table in /etc/OpenBTS.db.Standrd paths:/OpenBTS -- Binary installation and authorization keys./etc/OpenBTS -- Configuration databases./var/run/ -- Real-time reporting databases.The script apps/setUpFiles.sh will create these directories and install thecorrect files in them.Releases 2.5 and later include the smqueue SMS server.  It is NOT part of thenormal GNU build process with the rest of OpenBTS.  To build smqueue, gointo the smqueue directory and just type "make -f Makefile.standalone".Release history:ReleaseNameSVN ReposiorySVN RevComments1.0(none)SF.net??completed L1, L21.1ArnaudvilleGNU Radior10019 (trunk)1.2Breaux BridgeGNU Radior10088 (trunk)GNU Build, very early assignment1.3CarencroKSPr1 (trunk)first post-injunction release1.4DonaldsonvilleKSPr23 (trunk)fixed Ubuntu build error1.5EuniceKSPr39 (trunk)fixed L2 bugs related to segmentationremoved incomplete SMS directorymoved "abort" calls into L3 subclasses1.6New IberiaKSPr130 (trunk)import of all 2.2 improvements to non-SMS release2.0St. Francisville KSPr54 (smswork)SMS supportfile-based configuration2.1Grand CoteauKSPr70 (smswork)DTMF supportfixed more Linux-related build errors-lpthreadTLMessage constructorexpanded stack to prevent overflows in Linuxmoved gSIPInterface to main appfixed iterator bug in Pager2.2HoumaKSPr122 (smswork)added LEGAL noticeremoved Assert classesstop paging on page responsefixed Pager-spin bugfixed Transceiver spin bugsfixed 2^32 microsecond rollover bugreduced stack footprints in Transceiverfixed SMS timestampscheck LAI before using TMSI in LURreduced memory requirement by 75%removed PagerTestfixed stale-transaction bug in paging handlerfixed USRP clock rollover bugfaster call connectionnew USRPDevice design2.3Jean LafitteKSPr190?
