Apparently this FTTH problem happens to ONLY ME in the ALL of INDIA.

[Bolt]

Let me give some backstory before i tell whats going on.
2 years ago I posted on these forums asking for some advice, because I was frustrated from BSNL's frequently disconnecting dsl broadband (100-150 times/day, 100% honest).
No one except one guy replied and all he did was ask me which part of my city I live in and then disappeared.

Well, eventually I got rid of dsl and got myself FTTH connection.
Now the best part is my house is right next to exchange, all it took was 30 meters of wire to get the connectivity, so I got it running for very cheap. But for my luck, within 6 hours of the connection started working, it disconnected very similarly to how my dsl used to disconnect.

What happens is, say its working fine and the Link and Auth leds on ONT are on, suddenly net stops working and link/auth leds become unstable(they start blinking), after a few seconds they get stable and stay that way for like 2 seconds and bam, unstable again.

This cycle can continue for "x" qmount of time, sometimes as low as few minutes.
The longest it continued that I remember was 16 hours.

The people at bsnl office are confident that I am the only ftth user to have this problem in the whole nation, and it's something to do on my side instead of theirs. Obviously I asked what on my side could be causing the issue, he said most probably a virus in PC ?????.

I was literally dumb founded at that moment, but obviously didnt say anything, he told me to format my pc which I did.
I also didnt connect my pc to the ONT this time and using it thriugh wifi only so that his virus excuse won't work the next time I talk to him.

Anyways I have reported the problem to him again today and will update this thread with any progress, but new users please be warned, this is a shitty govt handled company, their after sales service will never be customer satisfactory anyway.
(That guy in the FTTH office is a sc caste who got the job because of reservation, not because he was good at it).

Well, that doesn't make any sense. 🤣😆

Couple of things that came to my mind

• From your description, its pretty clear that your FTTH ONT has trouble keeping a stable link to the BSNL OLT for whatever reason. That has nothing to do with your PC or Virus or whatever. 🤣 (Bless the BSNL guy!)
• As to why it has trouble keeping a stable link, there are couple of possibilities
  • The optical power at the ONT is lesser than the receiver's optical sensitivity, this depends on the ONT but it varies from around -22 dBm to -28 dBm or so I think. If this is the case, there might be some sort of damage in the cable? Or the power level is in the border. This can be easily checked with a optical power meter.
  • There could be an issue with the ONT device itself and its malfunctioning and its not able to keep a stable link.
  • There is an issue with BSNL OLT itself.
  • Maybe its the result of bad fibre splicing.

The last sentence could have been more polite. It is discriminatory.

That said, like @varkey said, it could be an issue with the power / electricity. When the power / voltage / current gets lower than certain limit (of the router, wifi, etc), the described scenario is very well possible.

 

[Bolt]

Yeah , there are more equations to the problem, than what the bsnl guy is telling me, anyways tomorrow more action will be taken as I have talked to their boss, he said he will have some "qualified engineers take a look". I'll keep this forum updated so people can have an idea about bsnl services.

P.S. Although bsnk have regularised the 777 and 1277 plans, officials here are only activating these plans for "new users" only not for regular old customers.

@pothi : I don't see how me telling the truth is discriminatory but them getting free jobs for their surnames is not. Anyways you can tell the same thing to the general caste technician who works under this sc guy because he scored more than him in the selection comission exam, yet did not get the job.

 

[Smh]

lets stay on topic 🙂

Update
Thought I should also mention what steps had been taken by bsnl in the past.
I have had this ftth for 6 months, and the problem started the same day my connection started working, since then my problem has been attended only 3 times.

First : The guy simply did some tweaks which he didn't want to explain in the ONT router page. But honestly speaking, i was sitting right next to him and I was not able to see any setting that he changed and then didn't switch it back to default. ?

Second: He said they will change the ONT but for 9 - 10 days no one came, so i reached the office myself and he gave me ONT there, I came home and switched it but within 10 minutes the new ONT gave same problem.

Third: He said ONT must be fine then, let's change the battery now, again no one came for over 2 months, and I didnt call them back too, i was too tired of it. Just called them yesterday only before posting here.

Current Update: yesterday he said, I should call him around 11 AM and he will see furthur into the problem. Since 11 AM i have messaged him, called him 3-4 times. He is not attending the call, nor giving a f*** about my message.

Have you tried changing the adapter of the ONT with a new one. May not solve your problem, but worth a shot. Just ask the BSNL office to give you a new one and also i see that you never mentioned the make and model of your ONT.

 

[Bolt]

The model is same BSNL is providing to everyone.
ONT Type-A Config Huwaei EchoLife HG850a.

Look at my last post Third attend, the guy said he will change the battery, but again if I don't keep calling them back every single day 10-12 times, they just seem to forget about it. I didn't call him back so for 2 straight months no one came to change the battery lol.

Complaint on CPGRAMS-Home and on twitter 🙂

 

[Bolt]

I had a talk about pgportal with the same guy lol.
He said, do it if you think it will help, they will process the complaint for a few days and ultimately the complaint will come to me only, I am already handling it, but if you want to create a mess, your choice (bhasad machani h to apki marzi).

His exact words in brackets. xD

The model is same BSNL is providing to everyone.

Well no BSNL does not provide the same model to everyone, there are quite a few different ONT's that BSNL is providing.

Although they did give me the same make and model but i was not provided with a battery instead i was given a normal Adapter which you get with all other routers so when you mentioned that he will replace the battery , i thought it might also be the adapter connected to the battery since i had a similar problem and they gave me a new adapter which solved my problem.

 

[Bolt]

Yeah as far as I know there were only 2 configurations Type A and B, so I had no idea they were giving different ONTs.
Anyways, I just had a talk 3 hours later at 2 PM with him, and he said he is going to change my ONT model with a different one (white wala XD) and also change the system from one node to another.
Currently i get power from Nayapura office, he will switch it to vallabhbari office but on Monday and that too only if I remind him by calling.

They don't let me use any 3rd party ONT as well, he said if anything goes wrong with that ONT only you will be 100% responsible and we wont do anything to help.
I wanted to use 3rd party ONT because the Huwaei one seems to be from ancient times, does not even support port forwarding.

 

[mayank yadav]

It does actually support port forwarding. I have explained it in this thread Want to connect D-Link router to BSNL ftth | BSNL FTTH Broadband

 

[Bolt]

I believe that method would only add port forwarding to the AP or Router not the ONT, but anyway i'll give it a shot.

And please also explain to me why Huwaei adds a feature that they don't want the customer to use? If it supports Port forwarding shouldn't we get the add or remove rule page on the router config page??🙄

EDIT : weeks ago I found this link : Configure Port Forwarding / Virtual Server Routing in Fiber to Home modems

The first answerer claims Huawei support team confirms this model doesnt support port forwarding, but the second guy tells a method pretty similar to yours, that is configure the ONT in bridge mode and get the router in PPPoE moed, then add port rules in the router.
Seems Legit, but for now i'll let the BSNL guy do what he said.

 

[Shubham]

@Bolt I thought BSNL supported third party ont. I know for sure that they support third party adsl modems. I was thinking to apply for ftth so i ma pretty sure the guy ther told me to get an ont or they will provide for it.
