|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.
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)....
A collection of various small (and not so small) hardware projects created as tools to the cellular research community
|SDR (Software Defined Radio)
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....
|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....
[old, abandoned] OsmocomDECT project by Patrick McHardy, implements a linux kernel based DECT stack.
