Name Description
osmo-uecups
SIM card related Projects
osmo-sim-auth
Sim Toolkit
SIMtrace 2

2nd generation SIMtrace: Uses same circuit board / peripherals as SIMtrace 1, but contains a SAM3 (Cortex-M3) instead of the SAM7 (ARM7TDMI) microcontroller. The SAM3 has a faster CPU and its internal USB peripheral offers more endpoints. This can be used for more features in the devie firmware, such as man-in-the-middle....

SDR (Software Defined Radio)

A collection of SDR related software + hardware projects. In particular, look at the sub-projects such as rtl-sdr, gr-osmosdr, osmo-fl2k, gr-gsm, libosmo-dsp

Hardware Projects

A collection of various small (and not so small) hardware projects created as tools to the cellular research community

osmo-e1-recorder

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)....

Erlang Core Network Signalling Projects

A set of almost complete Erlang projects implementing the core network protocol stacks from SS7/SIGTRAN over SCCP up to TCAP, MAP and CAP.

Currently not actively maintained due to lack of active customer/user interest.

multi-voltage USB UART

A small USB UART board with two CMOS UARTs exposed on 2.54mm headers.

The logic voltage can be manually selected at 1.8, 2.3, 2.5, 2.8, 3.0 or 3.3V

OsmoHNBGW

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....

cellmgr-ng

An utility to convert the circuit-switched A interface of a BSplus into SCCP-lite A-over-IP

OCTOI - Osmocom Community TDM over IP

Building a community TDM-over-IP network so retronetworking enthusiasts can interconnect equipment with ISDN, Frame Relay or other technologies using PRI (E1) or BRI TDM technology in a private TDM network.

libosmo-dsp

C-language library for common DSP (Digital Signal Processing) primitives for SDR (Software Defined Radio). They are part of the Osmocom project.

Cellular Modem Information

collects various bits of (low-level technical) information on cellular modems

libosmo-ranap

De- / encode RANAP messages and provide Iu client implementations (to OsmoMSC for IuCS and OsmoSGSN for IuPS).
Lives in the osmo-iuh git repository.

Distributed GSM

Distributed GSM architecture, suitable for de-centralized, autonomous networks with intermittent connectivity.

erlang/osmo_map

Erlang implementation of a TCPAP+MAP codec (encoding/decoding). You most likely want to use signerl, not this.

erlang/osmo_ss7

Erlang implementation of M2UA/M3UA/MTP3/SCCP/ISUP codec + utils

erlang/osmo_sccp

Erlang implementation of SCCP (ITU-T Q.71x)

erlang/signerl

Erlang implementation of TCAP + MAP Signalling Protocols, runs on top of osmo_ss7 and osmo_sccp

erlang/mgw_nat

Erlang MGW NAT/MASQ implementation

FidoNet

FidoNet related stuff

osmo-ccid-firmware

Firmware for Smart Card Reader implementing the USB CCID (Circuit Card Interface Device) Specification, based on Atmel ASF4. Used on the sysmoOCTSIM 8-way CCID reader.

gr-gsm

Gnuradio blocks and tools for receiving GSM transmissions
