1 | 1 | == The cellmgr_ng project == |
|
---|---|---|---|
2 | |||
3 | The cellmgr_ng was initially written to allow to hook a BTS/BSC behind a traditional E1 link |
||
4 | with MTPL1, MTPL2, MTPL3 to a soft switch supporting the the ipaccess protocol. The MTPL1 |
||
5 | and MTPL2 is handled by a vendor solution right now, everything starting from MTPL3 is |
||
6 | available in source. The code supports interfacing with the hardware encoders and can send |
||
7 | and receive RTP with AMR and is controlled with the MGCP protocol. |

9 | === Applications === |
||
10 | ==== cellmgr_ng ==== |
||
11 | This application implements forwarding of SCCP from the MTPL3 linkset to the IPA protocol, |
||
12 | it supports connection tracking to work around implementation problems of various BSCs |
||
13 | and to handle the event of network disconnection without taking the MTP Linkset down. |
||
14 | |||
15 | ==== udt_relay ==== |
||
16 | A simple version of the cellmgr_ng that just relays between the MTPL3 linkset and the |
||
17 | connection to a MSC or similiar system. |
||
18 | |||
19 | ==== osmo_stp ==== |
||
20 | This a Signalling Transfer Point or a Media Gateway. It can handle a MTP L3 linkset and |
||
21 | a M2UA connection. Right now it does not support fail over in M2UA but this can be added |
||
22 | easily. It has basic support for ISUP blocking/unblocking/reset. |
||
23 | |||
24 | ==== mgcp_mgw ==== |
||
25 | Use the OpenBSC MGCP Protocol and Network implementation and interface with the |
||
26 | hardware to provide the gateway from E1/T1 to IP/RTP. |
