elaborate a bit more what the bsc nat is all about

3 | 2 | laforge | The BSC NAT/MUX is the Base Station Controller Network Adress Translation / Multiplexer. |
4 | |||
5 | The BSC NAT/MUX makes NAT traversal of IP-based A interfaces (between BSC and MSC) easy. |
||
6 | |||
7 | The real BSC is opening its A interface through one TCP (or SCTP) connection to the multiplexer. |
||
8 | The multiplexer is opening its uplink A interface to the MSC. |
||
9 | |||
10 | The multipexer is rewriting SCCP source local references (as multiple BSCs could be connected) and |
||
11 | thus makes all of the real BSC's connected to the multiplexer appear as one BSC to your MSC. |
||
12 | |||
13 | Furthermore, it is listening on UDP port 2427 (MGCP Gateway) and is forwarding the MGCP messages via TCP (or SCTP) |
||
14 | to the BSC that should handle the endpoint. |
