osmo-ePDG - VoWifi Evolved Packet Data Gateway | A combined ePDG/AAA (IPsec gateway for VoWiFi/Authentication Authorisation Accounting) |
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. |
osmo-isdntap | 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. |
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.

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). |
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 |
linmodem | 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".
|
Qualcomm Linux Modems by Quectel & Co | Information / Research on the internals of Qualcomm Linux based cellular modems available from Quectel and other vendors |
