Loopback causing blacklisted ont

[orrville]

@orrville SN and MAC are completely different. If your ONT is loosing connection and red light keeps blinking, even though its in bridge mode, then OLT is blocking your ONT SN.

But in my case there is no red light blinking. PON is totally OFF or green and blinking.

If there is a way to change SN of my Digisol ONT, that would be worth a try.

@orrville Please check my updated post. It does seem to be the MAC address in EPON OLT.

@jayanta525 thanks, so looks like I need ONT that can allow me change MAC, and probably SN. I searched the forum but did not find anything. I guess there is nothing of sort out there.

@orrville I took apart the DBC ONT, exact one you linked. Good thing is that it has serial headers, just need to figure out the baud. I will let you know if I find something.

Just got root access through Serial@115200. Runs a normal Linux OS, lets see how far I can get.

Leaving the boot-logs here just in case someone comes along:

CPU: ZX279125@A9,600MHZ
RAM: 32MB
SPI Flash: 8MB

U-Boot 2013.04 (Jun 11 2018 - 09:23:51)

FULL:

Ubuntu Pastebin

Looking at the dmesg and result of ifconfig, it look like its running an older version of OpenWrt.
There seems to be two pon interfaces, pon and pon0.

Changing mac with ifconfig pon hw ether XX....XX seems to work.

UPDATE:

1. Confirmed that it runs OpenWrt:

#!/bin/sh

Seems its time to jump off to OpenWrt forums.

@orrville Yes, its possible to change PON MAC on the ONT you linked above.

I tested and the changes persists on reboot.

@hemant @jayanta525 please suggest cheap basic GEPON with GE port, no WiFi, no phone, BUT should be able to change Mac, sn, loid etc
How about this one?

REVO 1G xPON ONU-1G xPON ONU

multilinkonline.3dcartstores.com

I guess there is nothing of sort out there.

Possible in this one tho. And i belive its possible in every ONT using ZTE chipset.

Both MAC and SN.

And literally any config.

Great news! Can you please tell me how to do it?
I had SSH access, but that is gone with firmware update. I remember even with ssh, changing only eth0 did not make it stick. I used ifconfig commands.

 

[jayanta525]

get telnet/ssh access first. Or else you'll have to get console access through serial.

I will post all the details in github shortly.

 

[orrville]

I could get the ftp access, hopefully that is sufficient
