# <a id="tmtc-testing"></a> TMTC testing
The OBSW supports sending PUS TM packets via TCP or the PDEC IP Core which transmits the data as CADU frames. To make the CADU frames receivabel by the [TMTC porgram](https://egit.irs.uni-stuttgart.de/eive/eive-tmtc), a python script is running as systemd service on the flatsat PC which forwards TCP commands to the TCP server of the OBC and reads CADU frames from a serial interface. The PUS packets transported with the CADU frames are extracted and forwared to the TMTC program's TCP client. The code of the TMTC bridge can be found [here](https://egit.irs.uni-stuttgart.de/eive/tmtc-bridge). To connect the TMTC program to the TMTC-bridge a port forwarding from a host must be set up with the following command:

The OBSW supports sending PUS TM packets via TCP or the PDEC IP Core which transmits the data as
CADU frames. To make the CADU frames receivabel by the
[TMTC porgram](https://egit.irs.uni-stuttgart.de/eive/eive-tmtc), a python script is running as
`systemd` service named `tmtc_bridge` on the flatsat PC which forwards TCP commands to the TCP
server of the OBC and reads CADU frames from a serial interface.
You can check whether the service is running the following command on the flatsat PC
```sh
systemctl status tmtc_bridge
```
The PUS packets transported with the CADU frames are extracted
and forwared to the TMTC program's TCP client. The code of the TMTC bridge can be found
[here](https://egit.irs.uni-stuttgart.de/eive/tmtc-bridge). To connect the TMTC program to the
TMTC-bridge a port forwarding from a host must be set up with the following command:
```sh
ssh -L 1537:127.0.0.1:7100 eive@2001:7c0:2018:1099:babe:0:e1fe:f1a5 -t bash
````
Note: The encoding of the TM packets and conversion of CADU frames takes some time. Thus the replies are received with a larger delay compared to a direct TCP connection.
```
You can print the output of the `systemd` service with
```sh
journalctl -u tmtc_bridge
```
This can be helpful to determine whether any TCs arrive or TMs are coming back.
Note: The encoding of the TM packets and conversion of CADU frames takes some time.
Thus the replies are received with a larger delay compared to a direct TCP connection.
