A program to record traffic on E1 or T1 TDM interfaces to disk. This provides tcpdump-like functionality for TDM interfaces. You can configure on a per-timeslot bases if the raw bitstream should be recorded, or if a HDLC decoder should be used. Requires a high-impedance tap and two E1/T1 ports per link you want to monitor (one for Rx, one for Tx)....

The Osmocom Gb Proxy is a proxy for the 3GPP Gb interface (between BSS/PCU and SGSN). It allows you to aggregate many Gb links/connections into one. It also has the ability to convert between different Gb interface protocol stacking, such as from Gb-over-FrameRelay to Gb-over-IP....
A small program used to tap an E1 PRI line and obtain GSMTAP traces of the D channel as well as raw files with B channel content of each direction of each call.
Various modules for building lab/testing setups using an industry-standard 3U component carrier
This project targets a C-Language library providing an implementation and interface to manage a Modbus node in a Modbus bus.
This library relies heavily on libosmocore library and it is aimed at being used by applications using that same library.
The Modbus specs can be found here: https://www.modbus.org/specs.php...
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....

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:
RF delay simulator using the ADI Pluto SDR
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 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).
This is a project implementing the analog cellular systems used in Germany and other countries in the past. It provides base station implementation of A-Netz (German pre-cellular), B-Netz (German pre-cellular), C-Netz (German cellular), NMT (Scandinavian: Nordisk Mobil Telefon) and AMPS/TACS (American: Advanced Mobile Phone Service)....
|Osmocom Conferences (OsmoDevCon, OsmoCon, OsmoDevCall)

OsmocomBB is an Free Software / Open Source GSM Baseband software implementation. It intends to completely replace the need for a proprietary GSM baseband software.
|OsmocomBB SDR PHY
Up to now there was no software defined GSM mobile phone. The "SDR PHY for Osmocom BB" project aims to fill this void. The project is focused on the client side of GSM protocol stack, and bridging the gap between existing GSM stack implementation project and SDR hardware....
[old, abandoned] OsmocomDECT project by Patrick McHardy, implements a linux kernel based DECT stack.
This is the homepage of the Osmocom sub-project GEO Mobile Radio.
This project contains proof-of-concept code to send GPS assistance data to mobile phones using RRLP (Radio Resource Location Protocol) as well as inquiring/obtaining their geolocation using RRLP queries. It uses OsmoNITB to operate the GSM network, and a u-blox GPS receiver to obtain the assistance data....
This project aims at practical research and experimentation with the TETRA trunked radio system. See OsmocomTETRA.
|OsmoGGSN (former OpenGGSN)
This is a python-based test framework by which we can control a set of BTSs and Modems to execute full-system end-to-end verification tests. We use this within Osmocom to du full end-to-end testing with all our network elements and real BTS + RF + Modem Hardware....
An Open Source implenentation of a HNB-GW (HomeNodeB-Gateway), implementing the Iuh, IuCS and IuPS interfaces. It aggregates the Iuh links from femtocells (hNodeBs) and presents them as regular IuCS and IuPS towards MSC and SGSN (such as OsmoMSC and OsmoSGSN). It uses M3UA as signaling transport....
This is a first step towards implementing a minimal hNodeB upper layer part, mainly handling HNBAP/RUA/RANAP messages on the Iuh interface. This is not expected to be a full / usable hNodeB anytime soon [if ever].
