README

Welcome to the OpenBTS source code.


For free support, please subscribe to openbts-discuss@lists.sourceforge.net.
See http://sourceforge.net/mailarchive/forum.php?forum_name=openbts-discuss
and https://lists.sourceforge.net/lists/listinfo/openbts-discuss for details.

For additional information, refer to http://openbts.org.


These are the directories:

AsteriskConfig	Asterisk configuration files for use with OpenBTS.
CommonLib	Common-use libraries, mostly C++ wrappers for basic facilities.
Control		Control-layer functions for the protocols of GSM 04.08 and SIP.
GSM		The GSM stack.
SIP		Components of the SIP state machines ued by the control layer.
SMS		The SMS stack.
SR		The subscriber registry.
TRXManager	The interface between the GSM stack and the radio.
Transceiver	The software transceiver and specific installation tests.
apps		OpenBTS application binaries.
doc		Project documentation.
tests		Test fixtures for subsets of OpenBTS components.
smqueue		RFC-3428 store-and-forward server for SMS



By default, OpenBTS assumes the following UDP port assignments:

5060 -- Asterisk SIP interface
5061 -- local SIP softphone
5062 -- OpenBTS SIP interface
5063 -- smqueue SIP interface
5064 -- subscriber registry SIP interface
5700-range -- OpenBTS-transceiver interface

These can be controlled in the CONFIG table in /etc/OpenBTS.db.

Standrd paths:
/OpenBTS -- Binary installation.
/etc/OpenBTS -- Configuration databases.
/var/run/OpenBTS -- Real-time reporting databases.

The script apps/setUpFiles.sh will create these directories and install the
correct files in them.
