Information about the Altair "FourGee" 3100 - 3800 LTE modems
Project about Retro-Communication using BBSs, Modems, DFÜ, Points, etc ...
The goal here is to re-create the modem / bbs / mailbox communication systems of the (late) 1980s and 1990s.
We use the bbs-revival mailing list to coordinate...
An utility to convert the circuit-switched A interface of a BSplus into SCCP-lite A-over-IP
|Cellular Modem Information||
collects various bits of (low-level technical) information on cellular modems
|Cellular Network Infrastructure||
This is a group of Osmocom programs implementing cellular network infrastructure components for GSM, GPRS, EDGE, UMTS, HSPA, LTE and their associated interfaces and protocol stacks.
This includes components for classic circuit-switched GSM:...
legacy and/or unmaintained CNI projects

|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).
Distributed GSM architecture, suitable for de-centralized, autonomous networks with intermittent connectivity.
|E1/T1 Hardware Interface (including icE1usb)||
This is about various projects implementing diffrent types of E1/T1 interfaces, including osmo-e1-xcvr, as well as a passive e1-tracer and icE1usb, our latest ICE40 FPGA based USB-E1 adapter.
|E1/T1 Tap Adapter||
￼The Osmocom E1/T1 tap adapter allows you to tap into the communication of an E1/T1 line.
This is useful for tracing/analyzing communications on any type of E1/T1 based interface, such as A-bis, A and core network interfaces in GSM networks, as well as classic ISDN networks....
|Ericsson RBS 6xxx||
This project is an attempt at an independent set of publicly-available documentation of the Ericsson RBS6xxx family of base station products.
|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.
Erlang MGW NAT/MASQ implementation
Erlang implementation of a TCPAP+MAP codec (encoding/decoding). You most likely want to use signerl, not this.
Erlang implementation of SCCP (ITU-T Q.71x)
Erlang implementation of M2UA/M3UA/MTP3/SCCP/ISUP codec + utils
Erlang implementation of TCAP + MAP Signalling Protocols, runs on top of osmo_ss7 and osmo_sccp

|GSM Audio Pocket Knife||
The GSM Auido Pocket Knife is a small tool that can encode and decode all of the GSM codecs and can convert between various different frame formats, such as the RTP payload formats, those used by the TI Calypso DSP, the Racal 61x3 testers, etc. You can use it as a RTP sink to play back a RTP stream from OsmoBTS. ...
