There is no need for me to inform BSNL of this at the exchange ?

If the Teracom Modem does not shows up then the problem is solved, no need to inform to BSNL and dont change you precious Router. It's raelly a unick Router.

No this is not from wireless. Your case is unick and very interesting. Your Local Area Network connect through the Phone Cable to another Local Area Network like VPN where this type of theory is used. Your Local Area Network is 192.168.1.0 to 255 and the person whose area network also is the same. Some how this two network is linked, this is possible from the DSLAM in exchange. This DSLAM some how make a route between your network and with that person network, this is call virtual private network or VPN. Thats why I ask you to change the Network address. Hope it will solve your problem.

Just like to know, did you seen this problem when you using the pppoe from your Router.
in pppoe mode you see the wan IP address in your router.

If this goes OK then I want to ask you to check another methode. I will tel you later.

A) disconnect modem Rj11 from splitter. access 192.168.1.1.
Which device info /menu you get Wa 3002_g4 or dna A211-I page ?

--> DNA-A211- I.[/quote]

Tried this test on my own. Not sure if it would add any value or not.
Switched off and put on the router without the RJ11 cable connected at the splitter. This time, even without the RJ11 the router page was accessible. It was the ITI router that showed up.

@Indranil :
please take up from here.

@kartik316_3199
You can download Teamviewer, and allow access to your system
to @Indranil or @meetdilip when you are on line. ( connected to Internet )
to check modem settings/ system network settings etc.
I am now in a different Time Zone.

Yes, this problem did show up even when I was in PPPoe mode as I had discussed with Essbebe earlier.

And I have not seen the teracom page in the last 7 hours.. guess the problem is solved.. what other tests did u want me to conduct ?

Also, people here at my home want to take up this issue with BSNL as they are afraid of usage issues once that such a problem has shown up now. They say its good to have it recorded with BSNL.

@ essbebe

Thanks .. I'll see about team viewer if such a need arises...

The test I want to check is that go to your default IP address I mean change back to IP 192.168.1.1 and DHCP 192.168.1.2 and also change the IP of your LAN card to 192.168.1.2 and gateway 192.168.1.1, after save and reboot your Router Go to the WAN pages ( Remember plug off the RJ11 when you do that ) and Delete all PVI/VCI entry except 0/35 dont delete it. Now save and Reboot your Router and Plug in the RJ11 cable and check Teracom Router comes up or not.

It is really good to have record in BSNL but if the usages record shows OK no extra charges then I think it's OK no need to headache.

I will do what you have asked and post results shortly, indranil.
Meanwhile, I would like you to see the error message that I'm getting occasionally when connecting my dialer in bridge mode. Yesterday with the 192.168.1.1 router ip also I got this error a couple of times. Pls. refer screenshot attached. Bur when I try connecting a 2nd or 3rd time.. it gets connected. Is this okay ?

Now save and Reboot your Router and Plug in the RJ11 cable and check Teracom Router comes up or not.

Am I supposed to unplug the RJ 11 only when deleting the PVI/VCI entries ? I thought I had to do it when changing the lan ip address itself and did so. As a result, once I entered the lan ip details (DHCP option was not there) and clicked on save. (Not save and reboot) Then the router page went blank and did not come back at all. DSL was not stable as RJ 11 was not connected. So, I had to connect RJ 11 and immediately teracom page came up. Let me know if I need to repeat the whole thing again.. Am I supposed to do all the ip changing in the ITI page with the RJ 11 connected and remove it only when deleting the entries?

Edit: Redone the procedure again following your guidelines. Will observe if Mr.teracom shows up.

Please ignore. . You have edited your message.

RESET the modem and see this link.
( RESET access in rear, or unit bottom right side a small round hole)
Should be identical to WA 3002-G4 unit.
SL2_141 (Type-B) ADSL MODEM MULTIUSER CONFIGURATION

hmm.. so far no teracom... how would deleting the other values have an effect like this ?

@karthik316_1999
did you delete the other entry in WAN pages and test it ?

"Am I supposed to unplug the RJ 11 only when deleting the PVI/VCI entries ? "

Yes you have to unplug the RJ11 cable during changing the IP 192.168.0.1 to 192.168.1.1 and DHCP and deleteing the other value in WAN pages except 0/35

" As a result, once I entered the lan ip details (DHCP option was not there) and clicked on save. (Not save and reboot) Then the router page went blank and did not come back at all. "

Because you change the router IP 192.168.0.1 to 192.168.1.1 thats why the router page went blank. after changing the IP 192.168.1.1 and saving it change your LAN IP addess 192.168.1.2 and gate way 192.168.1.1

during the modification make sure your RJ11 is unpluged and after your settings complete then plug your RJ11 and check for MR.Teracom.

Yes, I have done all that. So far teracom hasn't shown up... can u brief me how this has solved the problem ? Just interested to know..!

This is all happen because of the DSLAM in your exchange.
The other vpi/vci value which is not using for the authountication one of them also enable in your DSLAM. In your DSLAM that port ( VPI/VCI ) which is responsible for Mr.teracom used as a VPN or makes a route to your DSLAM port with another person's DSLAM port and The person who using the teracom Router has the same VPI/VCI value enable. So when the DSLAM makes a direct path with that person's router in that time you are browsing the Teracom Router even you can browsing the internet from his/her modem. This is completely a VPN connection. I think this is happen after the IP TV install. Because when need to install the IP TV need some tweak in the DSLAM.

Just like to know that do you test the download speed when you connect to the Teracom. I just like to know what is the speed you getting when you connect to Teracom.

Just been reading this interesting problem thread, and I wonder if you guys know that this has happened before to others? I do remember it coming up on vinuthomas.com quite some time ago, several years I think. I think (but my memory is dim) that there was some suspicion expressed that BSNL was doing some bad setup which allowed its routers to route private address space IPs, making it posssible to reach somebody else's 192.168.1.1 instead of the one on your own net. Crazy? Sounds it, sure, but here it is happening to someone else all this time later.

I've no idea what to google to find this, but it must be findable somehow!

I had just been spending a couple of mins doing some reading and trying to understand how actual Virtual Private Networks function. Looks like they are basically used to create LAN to LAN connections without geographical limitations.

I also agree with the DSLAM thing. Way back when my iptv was configured, I had serious trouble getting the desired SNR values on my connection. (They needed minimum 15db whereas what I had was just 8-9db. Spent almost 1 month checking/replacing wires, changing cable pair (at the junction box level ?) etc. but nothing worked. Finally, then the iptv guy went to the exchange and made some 'tweaks' in my DSLAM that resulted in an instant boost to my SNR ! Till date I have been wondering what he had done that day ! Any networking guru is welcome to answer this Even now, my downstream SNR is just 15.9 but the upstream is 24.5. Don't know if this is normal...

But what is surprising is that how this VPN is taking place between my ITI router and Mr.X 's teracom router ? When reading various articles about VPN's online, I came to know that such connections usually take place with "high security measures/systems". Does this mean that the DSLAM at my exchange is faulty ? Cuz.. I believe each of the DSL connections (such as mine & Mr.X) have dedicated ports allocated with the DSLAM, right? Or is it that there is a possibility that two users share the same port also?!

Also Indranil, this thing about me being able to use Mr.X's connection. I guess that's why I was able to browse the internet even after having disconnected my dialer when in bridge mode? But then anyways, this lasted only for a few minutes. You said :

Let me get this clear. You are right in your 1st part. Though I had IPTV installed several months, it has been long since I had disconnected it and when speaking to the BSNL guy, he said my IPTV is "Inactive".

- But one fact that could help us is that my line rate (as shown in the ITI device info page) is still fixed at 6 mbps (downstream) and 0.5 mbps (upstream).I have made many requests to BSNL to re-cap my line rate to 2 mbps as appropriate for my Home 500 plan (cuz I believe a lesser line rate is likely to give you more snr values? especially when located far away from local exchange )but they never respond. Does these 6 mbps and 0.5 mbps values mean that the 'iptv port' is still active in my DSLAM and it is through this port that the VPN connection to teracom is taking place?

- An yes to the previous question brings up another question to me. The VPI/VCI such as 0/35, 0/32, .. etc (total 7 listed in my ITI router's wan info page before me deleting them) are the same for all the BSNL router's right? It is only the individual port that each user has at the DSLAM which makes their connection unique, tracking their internet usage possible, etc. A particular service, say the Internet uses the 0/35 VPI/VCI values/port/interface. Similarly, another service such as iptv might use a specific VPI/VCI value/port/interface, correct? And this VPI/VCI value/port is common for all the iptv users at my exchange. That being the case, how come the VPN connection is taking place just between me and Mr.X and why not me and Mr.Y or Mr.Z?! I mean.. could there be anything more that me and Mr.X might actually be sharing?

Sorry if my questions are too many! I'm sure it is only at places like these.. I can get answers and not the exchange for sure! Man.. this thread is interesting I'm learning a lot about networking

And with regards to the connection speed with teracom router, do you want me to test the speed when and if I'm able to browse the internet with the dialer disconnected? Also, in order to do this.. I need to get back the VPI/VCI values that I deleted and for this I need to hard reset the router, right..

Updating :
hey essbebe... guess u said ur moving on to a different time zone or something n hence wont be active in the discussion... but i'm seeing u in other threads

Problem passed on to @Indranil.

@essbebe

can u pls. PM me ur mail id or accept PM's from others for a little while.. need to share something with u..

Not possible to tell you untile I log in to your Exchange DSLAM consol port.

Yes, the VPN take place with "high security measures/systems" If we Implement the security on that connection otherwise it's a simple Private Network, only difference it's connect virtually through public network to remote Private Network, simple meaning is VPN creates LAN to LAN connections without geographical limitations.

Yes, you are right, each user has own port to use.

BSNL dont re-cap your port speed because when BSNL see your port speed which is capable to transfer data according to your BB PLAN. Some user asked here how to increase their port speed. I suggest them to apply for IP TV or High speed plan and giving it back after a month or use it continue.

Yes, the lesser line rate likely to give you more snr values.

High Port speed do not mean that you have IP TV Active. High port speed meaning you can transfer data at that value.
When your BSNL said your IP TV is deacivated then it's deactivated and this is not the port from where the MR.Teracom arrived in your home.

Yes, you are correct.

No, it's not.

Yes, you are right, for IPTV the VPI/VCI settings is (0/100) and need to bridge.

I cant say this, need to see console of your DSLAM.

Yes, please check the download speed if you connect to teracom router.
You need hard reset to your router for get back the previous all values.
Also check the VPI/VCI 0/100 in Teracom Router. What is done in there.
But dont delete or modify the value.
