Gnuradio blocks and tools for receiving GSM transmissions
Here is the generic Linux Modem. This modem is totally software, it means that all the DSP stuff is done by the main CPU, as in some so called "winmodems".

|Core testing infrastructure||
Issues that have to do with our core testing infrastructure (TTCN3 issues, docker setup) go here.
Issues specific to one test component should still be filed in the respective projects (e.g. osmo-msc).
legacy and/or unmaintained CNI projects
OP25 is a not-for-profit project to bring together folks that are interested in implementing APCO P25 using a software-defined radio. Our goal is to build a software-defined analyzer for APCO P25 signals that is available under the GNU Public License (GPL)....
|OpenVizsla USB tracer/analyzer||
OpenVizsla is a Open Hardware FPGA-based USB analyzer for USB Low-Speed, Full-Speed and High-Speed. Unlike other similar devices on the market, hardware design files are available as well as full source code for the firmware and client software of the device....
osmo-remsim is the Remote SIM software suite used to manage a set of phones/modems and a set of SIM/banks as well as the dynamic mappings of SIM cards to their remote phones/modems.It consists of:
OsmoBSC is an Open Source BSC (GSM Base Station Controller) with A-bis/IP and A/IP interface. It supports a variety of BTS Vendors/Models, including some Siemens, Nokia, Ericsson and ip.access models. However, main focus during the last 5+ years is OsmoBTS based BTSs....
OsmoBSCNAT is an A-interface aggregator that can aggregate many A-interface links from many BSCs and present them as one A interface towards a MSC. Most normal networks will not need this component, it only serves some special use case scenarios. It requires SCCPLite and doesn't work with 3GPP AoIP....
OsmoBTS is an Open Source GSM BTS (Base Transceiver Station) with A-bis/IP interface. It implements support for a variety of PHY/Hardware, such as sysmocom sysmoBTS, OCTSDR-2G and LiteCell 1.5, but also general-purpose SDR boards such as USRP or LimeSDR via OsmoTRX....
Osmocom Call Control. A new, protocol-agnostic way of interfacing call control of various different protocols with each other. Currently used within the osmocom-analog domain and with several endpoints.
Osmocom Cell Broadcast Centre (CBC). It is the heart of the Cell Broadcast Service (CBS) as well as a variety of disaster/emergency warning systems (PWS).
Osmocom Clock Generator board, using the Si5351C clock synthesizer to derive up to 8 different clocks from a single clock reference, such as a 10MHz GPS-DO or OCXO.
|Core Network (CN)|
Osmocom E1 daemon; used as a "software defined" implementation of E1, where the framer and HDLC controller is implemented inside osmo-e1d and a relatively simple hardware (such as USB attached hardware) interfaces with the actual E1 physical line.
Osmocom PCAP utilities, such as a distributed client/server capture architecture. It allows a number of PCAP probes on remote hosts, feeding captured packets to a central host in the network. Each probe can have different capture filters. There are multiple options for the protocol between probe and central host....
