G-010S-A

Introduction

This repository is meant to gather all available information on the G-010S-A GPON SFP, including firmwares and modifications.

Detection and power-up

For the SFP to be detected, and/or for the host to give it power, the pin 6 might need to be shorted to the ground.
See https://rsaxvc.net/blog/2020/8/15/Nokia_G-010S-A_Pin_6_Issue.html.

Configuration access

The default IP address is 192.168.1.10, there are two interfaces :

SSH : user ONTUSER, password SUGAR2A041
HTTP : user adminadmin, password ALC#FGU

Modern SSH configs might not be able to negotiate a connection with the legacy ciphers by default. If that is the case, run the following usage:

$ ssh -o KexAlgorithms=+diffie-hellman-group1-sha1 -o HostKeyAlgorithms=+ssh-rsa ONTUSER@192.168.1.10

The commands shown below are all meant to be used on the SSH command-line.

2.5Gbps

In addition to the standard 1Gbps SFP (SGMII), the chipset supports 2.5Gbps HSGMII.

It can be configured to auto-select 1Gbps/2.5Gbps :

fw_setenv sgmii_mode 5

The current speed can be checked with :

onu lanpsg 0

The link_status value shows the speed :

4 => 1Gbps
5 => 2.5Gbps

The number of devices which support the 2.5Gbps mode is limited.
A SFP+ network card based on BCM57810S can be used with a patched Linux/FreeBSD driver : https://www.dslreports.com/forum/r32230041-Internet-Bypassing-the-HH3K-up-to-2-5Gbps-using-a-BCM57810S-NIC

GPON configuration

Connection state

onu ploamsg

The returned curr_state shows the usual Ox state.
For proper operation, the state should be O5, and be stable.
If stuck in O1, check the physical connection of the fiber.
For other cases, your ISP might require proper values for authentication, see below.

S/N

To check the current serial number :

onu gtcsng

To set the serial number to ABCD012345678 :

ritool set MfrID ABCD
ritool set G984Serial 012345678

PLOAM password (SLID)

To check the current password (the password field contains decimal values of ASCII characters) :

onu gtccg

The value can be changed using the web interface.

Firmwares

All known images are generated from Lantiq OpenWRT 14.07 (7.5.3).
The firmware are u-boot images (legacy uImage) containing the Linux kernel, followed by a squashfs root filesystem.
Only the oldest ones have Lantiq omcid present (but not used), all use the ALU/Nokia omciMgr.

The firmwares directory contains different images :

IMAGEVERSION	SOFTWAREVERSION	BUILDDATE	LATEST_REV	omcid present
3FE46398AFGA95	AFG.A95p02	20170328_1144	17850	Y

3FE46398BGCB22	BGC.B22	20210125_1451		N

Upgrade

To flash a different firmware, the first step is to determine the current running image (0 or 1) :

ONTUSER@SFP:~# upgradestatus
***** get current running image *****
current running image is  image0 !
...

Then the other image must be flashed, the bootloader configured to boot it, and we can reboot :

mtd write image.bin image1
update_env_flag 1
reboot
