|EPC - Evolved Packet Core
Information about the Evolved Packet Core (EPC) and related open source projects
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)....
|osmo-ePDG - VoWifi Evolved Packet Data Gateway
plan for upcoming open source ePDG (IPsec cateway for VoWiFi)
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....

|Radio Access Network
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....
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....
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].
OsmoTRX is a GSM Radio Modem based on a fork of the OpenBTS Transceiver program. It is intended to be used with the osmo-bts-trx variant of OsmoBTS in order to build GSM base stations with Abis/IP interface from general purpose SDR hardware such as USRP or LimeSDR devices....
|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
A collection of various small (and not so small) hardware projects created as tools to the cellular research community
|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.
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.
|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....
