## Serial

The stick has a TTL 3.3v UART console (configured as 115200 8-N-1) that can be accessed from the top surface. It's near the SFP header. TX, RX and ground pads need to be connected to a USB2TTL adapter supporting a logic level of 3.3V.

This ONT supports dual boot. 

`kernel0` and `rootfs0` respectively contain the kernel and firmware of the first image, `kernel1` and `rootfs1` the kernel and the firmware of the second one

# XGS-PON ONU status

To access Cortina Shell (needed to check OMCI stuff and XGSPON status) you can use the following command:

```sh
# app-cli
```
This console can also be reached by opening a telnet connection to `192.168.0.1:2233`


## Check Activation Status (from app-cli and telnet\ssh session)

Open two telnet sessions, one to `192.168.0.1` and one to `192.168.0.1:2233`

Before running any commands on the second connection, on the first one tail the `/var/log/messages` file (needed to see the output of the next steps)

```sh
Cortina> enable
Cortina# config
Cortina(config)# aal
Cortina(config-aal)# xgpon
Cortina(config-aal-xgpon)# show activation_state 0
```

You will see the following output on the first shell:

## Setting ONU GPON PLOAM password

### Web procedure

<form id="hisense-ploam" novalidate>
    <div class="form-floating mb-3">
        <input type="text" class="form-control" placeholder="PLOAM in ASCII" name="ploam" id="ploam" required>
        <label for="ploam">PLOAM in ASCII</label>
        <div class="invalid-feedback">
            Please provide a valid PLOAM password.
        </div>
    </div>
    <div class="mb-3">
        <input type="submit" class="btn btn-primary" value="Encode!">
    </div>
    <div class="language-plaintext highlighter-rouge">
        <div class="highlight">
            <pre class="highlight" id="ploam-encoded">
            </pre>
        </div>
    </div>
</form>

<script type="text/javascript" src="/assets/js/generated/LTF7267-BHA-ploam.js"></script>
<script type="text/javascript">
    var hisensePloamForm = document.getElementById('hisense-ploam');
    var hisenseResult = document.getElementById('ploam-encoded');
    hisensePloamForm.addEventListener('submit', (event) => {
        event.preventDefault();
        if (!hisensePloamForm.checkValidity()) {
            event.preventDefault();
        } else {
            const data = new URLSearchParams(new FormData(hisensePloamForm));
            hisenseResult.innerHTML = hisensePloam(data.get('ploam'));
        }
    });
</script>


### Normal procedure

This ONT seems to be supporting a PLOAM password up to 288 bits in lenghth (36 ASCII characters, 72 Hex digits).

The PLOAM password is stored into 32 bit chunks (4 ASCII characters / 8 Hex digits), each byte swapped. 

So, starting from the following PLOAM in ASCII format

```
A1B2C3D4E5
```

It gets translated into the following HEX value:

```
0x41314232433344344535
```

Which is then split into the following blocks (the last block gets padded with 0 to reach 8 digits)

```
BLOCK 0: 0x41314232
BLOCK 1: 0x43334434
BLOCK 2: 0x45350000
```

Each block is then byte swapped (i.e. read each sequence of two digits from right to left)

```
BLOCK 0: 0x32423141
BLOCK 1: 0x34443343
BLOCK 2: 0x00003545
```

And then you can finally persist it by changing the configuration file

```sh
# vi /config/scfg.txt
```

Append lines below to the file and save it to change the PLOAM password

```
INT             CFG_ID_PON_REGISTRATION_ID0                                         = 0x32423141;
INT             CFG_ID_PON_REGISTRATION_ID1                                         = 0x34443343;
INT             CFG_ID_PON_REGISTRATION_ID2                                         = 0x00003545;
```

Reboot the ONT to apply the change.

# Known Bugs
- `ALCL` OLT mode uses some static configurations on MIBs, so if your OLT has strict configuration checks it might not work properly
- During initial tests the only currently working mode of the stick is `PPTP EthUni`
- Stick can be configured also emulate `VEIP` mode(adding it to the scfg.txt file), but current firmware doesn't link correctly the XGBE interface, so no traffic is passing between LAN and PON interfaces
