| 3 | RSPRO is the Remote SIM PROtocol, which is used between the osmo-remsim components (bankd, client, server). |
||
| 4 | |||
| 5 | It is a binary protocol running inside TCP, with an IPA ("GSM over IP") multiplex layer in between. |
||
| 6 | |||
| 7 | The actual protocol is described in ASN.1 and uses BER encoding. |
||
| 8 | |||
| 9 | The ASN.1 syntax can be found inside the osmo-remsim.git repository, see http://git.osmocom.org/osmo-remsim/tree/asn1/RSPRO.asn |

| 15 | You have to manually select "Decode as..." "GSM over IP" for TCP port 9999 and 9998 in order to get the decode. |
