About OpenBSC ============= OpenBSC is a minimalistic implementation of the GSM Network, with particular emphasis on the functionality typically provided by the BSC, MSC, HLR, VLR and SMSC. Its currently supported interfaces towards the BTS are: * Classic A-bis over E1 using a mISDN based E1 interface. In other words, you can connect existing GSM Base Transceiver Station (BTS) through E1 to OpenBSC. So far, we have only tested the Siemens BS-11 Test reports with other BTS are much appreciated! * A-bis over IP as used by the ip.access nanoBTS product family You can find the project documentation at http://openbsc.gnumonks.org/ This project is still in its early days, and there are lots of areas where it doesn't behave as per GSM spec. Harald Welte libosmocore =========== Please note that as of March 2010, OpenBSC has a dependency to a library called "libosmocore". You can obtain that library from git://git.osmocom.org/libosmocore.git
