2 | 2 | h2. The cellmgr_ng project |
|
3 | |||
4 | |||
5 | 1 | The cellmgr_ng was initially written to allow to hook a BTS/BSC behind a traditional E1 link |
|
6 | with MTPL1, MTPL2, MTPL3 to a soft switch supporting the the ipaccess protocol. The MTPL1 |
||
7 | and MTPL2 is handled by a vendor solution right now, everything starting from MTPL3 is |
||
8 | available in source. The code supports interfacing with the hardware encoders and can send |
||
9 | and receive RTP with AMR and is controlled with the MGCP protocol. |
||

12 | h3. Applications === |
||
13 | cellmgr_ng ==== |
||
14 | 1 | This application implements forwarding of SCCP from the MTPL3 linkset to the IPA protocol, |
|
15 | it supports connection tracking to work around implementation problems of various BSCs |
||
16 | and to handle the event of network disconnection without taking the MTP Linkset down. |
||
17 | |||
18 | 2 | ||
19 | h4. udt_relay |
||
20 | |||
21 | 1 | A simple version of the cellmgr_ng that just relays between the MTPL3 linkset and the |
|
22 | connection to a MSC or similiar system. |
||
23 | |||
24 | 2 | ||
25 | h4. osmo_stp |
||
26 | |||
27 | 1 | This a Signalling Transfer Point or a Media Gateway. It can handle a MTP L3 linkset and |
|
28 | a M2UA connection. Right now it does not support fail over in M2UA but this can be added |
||
29 | easily. It has basic support for ISUP blocking/unblocking/reset. |
||
30 | |||

32 | h4. mgcp_mgw |
||
33 | |||
34 | Use the [[OpenBSC]] MGCP Protocol and Network implementation and interface with the |
||
35 | 1 | hardware to provide the gateway from E1/T1 to IP/RTP. |
