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. Its only current interface is a mISDN based E1 interface utilizing the A-bis protocol between BSC and BTS. In other words, you can connect an existing GSM Base Transceiver Station (BTS) through E1 to OpenBSC. So far, it has only been tested with the Siemens microBTS BS-11. Test reports with other BTS are appreciated! This project is still in its early days, and there are lots of areas where it doesn't behave as per GSM spec. December 29, 2008 Harald Welte
