| == Configuring OsmTRX |
| |
| OsmoTRX will read the configuration at startup time and configure the |
| transceiver accordingly after validating the configuration. |
| |
| OsmoTRX can handle several TRX channels, but at least one must be configured in |
| order to be able to start it successfully. Channels must be present in the |
| configuration file in incremental order, starting from 0 and be consecutive. |
| |
| Example configuration files for different devices and setups can be found in |
| `doc/examples/` in 'osmo-trx' git repository. |
| |
| === Documented example |
| |
| .Example: Static GGSN/APN configuration (single catch-all GGSN) |
| ---- |
| trx |
| bind-ip 127.0.0.1 <1> |
| remote-ip 127.0.0.1 <2> |
| base-port 5700 <3> |
| egprs disable <4> |
| tx-sps 4 <5> |
| rx-sps 4 <6> |
| chan 0 <7> |
| tx-path BAND1 <8> |
| rx-path LNAW <9> |
| ---- |
| <1> Configure the local IP address at the TRX used for the connection against `osmo-bts-trx`. |
| <2> Specify the IP address of `osmo-bts-trx` to connect to. |
| <3> Specify the reference base UDP port to use for communication. |
| <4> Don't enable EDGE support. |
| <5> Use 4 TX samples per symbol. This is device specific. |
| <6> Use 4 RX samples per symbol. This is device specific. |
| <7> Configure the first channel. As no other channels are specified, `osmo-trx` assumes it is using only one channel. |
| <8> Configure the device to use `BAND1` Tx antenna path from all the available ones (device specific). |
| <9> Configure the device to use `LNAW` Rx antenna path from all the available ones (device specific). |
