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