+# Free/Iliad network
+
+Iliad's (Italy) PON network is delivered through two types of technology: GPON or EPON where available. The latter is not actually pure 10G-EPON but DPoE (DOCSIS Provisioning over EPON), confirmed by analyzing the physical layer signals.
+
+Using a Xilinx Kintex 7 FPGA with an integrated logic analyzer, an optical module has been connected to the FPGA's transceiver. The transceiver synchronized successfully and the sync header sequence was the one expected for 10G-EPON: a FEC codeword is a sequence of 31 words. Those words have a sync header binary value of `10` or `01` repeated 27 times corresponding to the original message plus `00, 11, 11, 00` corresponding to the FEC parity information. Discarding the latter part and descrambling the remaining data, the packets have been retrieved.
+
+As an example, a packet starts with `55 d5 55 1b 3c 07 5f` in hex, which corresponds to a DPoE (10G) preamble (actually it's missing one starting `0x55` byte but the CRC8 at the end is correct nonetheless).

+The BCM55030 is a 10G-EPON ONU/ONT.
+The BCM55030's UNI (User Network Interface) side should be capable of 4xSGMII (1 GbE) or 1xXAUI (10 GbE) or 1xXFI (10 GbE SFP) or 1xRGMII, but only one SGMII lane is actually routed.
+UNI link won't go up when connected to a media converter or directly to a NIC.
+
+## Serial
+
+The serial port is easily accessible at TP5 and TP6. A prompt is available without authentication, it is structured as a tree of directories. To navigate type the subdirectory name. To go back type `/` and hit enter. To list available commands type `help`.
+
+Available commands:

+`mem/rf [start address] [lenght]` reads bytes from the flash memory, wraps every 512 kB.
+
+## List of partitions
+
+The flash memory is not actually partitioned, upon reset the CPU loads from address 0 (reset vector) and jumps to another address ([page 74](http://me.bios.io/images/d/dd/ARCompactISA_ProgrammersReference.pdf#%5B%7B%22num%22%3A177%2C%22gen%22%3A0%7D%2C%7B%22name%22%3A%22XYZ%22%7D%2C72%2C157%2C0%5D)). Each section ends with its CRC.

+
+(End address is non-inclusive)
+App 1 and App 2 sections are located at a distance of 512 kB (0x80000) from each other. This probably means that the CPU is capable of addressing only 512 kB of flash. It can be verified also by running the `mem/rf` command, which wraps every 512 kB.
+
+# Userful files and binaries
+
+# EEPROM
+
+There is an SFP plug on the UNI side with an embedded EEPROM.

+# Free/Iliad network
+
+Iliad's (Italy) PON network is delivered through two types of technology: GPON or EPON where available. The latter is not actually pure 10G-EPON but DPoE (DOCSIS Provisioning over EPON), confirmed by analyzing the physical layer signals.
+
+Using a Xilinx Kintex 7 FPGA with an integrated logic analyzer, an optical module has been connected to the FPGA's transceiver. The transceiver synchronized successfully and the sync header sequence was the one expected for 10G-EPON: a FEC codeword is a sequence of 31 words. Those words have a sync header binary value of `10` or `01` repeated 27 times corresponding to the original message plus `00, 11, 11, 00` corresponding to the FEC parity information. Discarding the latter part and descrambling the remaining data, the packets have been retrieved.
+
+As an example, a packet starts with `55 d5 55 1b 3c 07 5f` in hex, which corresponds to a DPoE (10G) preamble (actually it's missing one starting `0x55` byte but the CRC8 at the end is correct nonetheless).

+## Serial
+
+The serial port is routed through the USB-C port used for power (which is PD compliant, tested with a notebook power supply). The pins are SBU1 and SBU2, reversal is handled using an open drain buffer (SN74LVC2G07) so a pull-up resistor on RX is needed. On the power daughter board TP7 is TX and TP8 is RX. There is also a USB differential pair routed through the USB-C connector but there is no use for it yet.
+At the moment nothing more than a boot log is available. [^bcm61650hack] [^freeboxhack]

+
+This ONT supports dual boot, as visible from the presence of `kernel0` and `kernel1`, which contain the rootfs.
+The boot images can be swapped with the following command:
+
+```sh
+upgradetest switchver X
+```
+
+Where `X` can be `0/1`, based on the image you want to boot from.
+
+
+You can also clone the currently running image into the other slot using this command:
+
+```sh
+syn_version
+```

 In general, these devices do not have enough customisation to allow the required parameters to be changed other than the GPON Serial Number and GPON Ploam Password. This means that in most scenarios these devices with ONT w/o MAC are not flexible enough to be used as a replacement for an ISP-provided ONT.
 
+Nevertheless, on Hack-GPON routers supporting SFP w/o MAC will arrive, with at least the modification of GPON Serial Number and GPON Ploam Password.
