Thread: BSNL broadband problem. Pl help.

I am from Goa and purchased BSNL broadband in Goa exactly a year ago.

I am on the 750 plan and to tell you honestly, mine is not broadband, it disconnects all the time. I have gotten it checked, I have made the linesman change the underground jointing, given me a new dp box, a new line to my house, a new modem, re-installed drivers again. Practically everything. But I keep facing drops all the time.

Now am suspecting that nothing can be done as the problem could be underground, till the main box, or till the exchange.
What do i do? When i use skype and gtalk, i get disconnected so very otfen. The engineer, has told me the line parameter testing is ok, when mt UT starcom modem modem detects the following values.

SNR Margin (db) Upload ---26.5 Download --- 5.6

Attenuation (db) Upload --- 31.0 Download --- 17.5

SNR is variable and not constant, sometimes it shows upload around 9 and download as 12, and sometimes when i get a dropped call i get values in minus. Is the engineer who is doing the parameter testing, fooling me?

What do i do? Is mine a solvable situation, or is it the underground line from the exchange, that they are unable to touch?

Please help me. I am fed up.

Select Mod : only GDMT and T413 and recheck SNR/attn data.
Also change to OpenDNS 208.67.220.220. and 208.67.222.222
Are you using the USB PORT?
Present Modem model UT300R2U?

Hello essbebe,

I am using the UT300R2U, (i also have a dlink GLB 802 C)

Are you implying, DSL settings tab in the modem menu?

Do i uncheck the others? I mean, The G-lite, ADSL2, the AnnexL as well as the ADSL2+ check boxes? and keep the ones that you have mentioned.Theni hit the save/apply button right?

what does this do. I am aware the G.dmt is the standard for bsnl right?

hi ,

why is it that when i save the settings and after some time after switching the modemon, i get the old settings back again, could you pl help me on this?

I tick the settings as you say, then i save/apply.
It shows the settings.
Then i switch off the modem after 5 min, it shows the default settings again.

do i need to save/reboot the modem. I tried that once, but my modem does not function afterwards....

my apologies...
why is it that the modem reselects the others when i have exclusively checked the g.dmt and T413? I have hit the apply settings tab. Do i need to save/reboot?

I visited the exchange and they told me that the line is ok and blah blah. They said they may have to reset the port and thats the last option...

kindly reply

I have done as you have advised,

The values are as follows

SNR Margin (db) Upload ---20.5 Download --- 9.3

Attenuation (db) Upload --- 17 Download --- 32

In WAN page there could be an option AUTO.
Did you check with GLB802C modem ?

Report only SNR Attn Mod selected data now for both modems.

Ensure LIne ===>>adsl splitter ==LINEport RJ11
Modem Port ====>>>rj11 to modem
PHONE port =====>>Rj11 to ALL phones
For extension phones use addl additional ADSL splitters.

How stable is the connection now ?

Hi with regard to the UT starcom modem I managed to getthe values

SNR Margin (db) Upload ---20.5 Download --- 9.3

Attenuation (db) Upload --- 17 Download --- 32

With regards to the dlink modem i get these values

Local Tx Power: 12.1 dB
Remote Tx Power: 20.5 dB
Local Line Atten.: 32.5 dB
Remote Line Atten:17.5 dB
Local SNR Margin:6.5 dB
Remote SNR Margin:14.0 dB

The status is ADSL mode, I tried g.dmt with UT starcom and after sometime....kaput! but before that when in g.dmt mode, the snr increased by one value. Thats all

With regard to dlink. when i try it. it asks me for some proper combination and says invalid combination.

Kindly help...

1. seems line problem. Ask BSNL to change the port.
2.How far you are from the exchange ? 3 to 4 Km?
3. Will post details about Glb802C later.
You should have an installation Cd and a "wizard" for settings.
4. How you connect Dialer mode or "Always on " mode ?
5. You did not mention details about phones in your residence.

Update 1125PM
about 3. new unit and no quick usage guide available.

Hi essbebe,

I feel it is a line problem,

1. The tel ex.guy said he will check the port, is this port some hardware at the exchange? i mean is it in racks? as he said he may have to check the port. How is the port related to the line prob?
2.I am a km away from the exchange.
3. ok...I have used the cd, to install the dlink. but it was only for username and pwd
4.I have no dialer, i switch on themodem, connected to my dir 300 wireless router, then to my pc. therefore i assume it to be always on mode.
5. I have the main line, connected to the adsl splitter, one goes into my modem, The other line goes to two phones (via another adsl splitter as u now requested), one cordless and a landline., so I have eliminated any joints here.

Main line------> adsl splitter I-------> modem
I--------> Tel line -------> another adsl *

*splitter I----> cordless
I-----> landline (these are very close and not far away, so no joint problem.

Putting a filter here does not cause any prob right?

I--------> Tel line -------> another adsl *
*splitter I----> cordless
I-----> landline I-----> landline (these are very close and not far away, so no joint problem.

Here could be the problem.
MAIN Telephone BOX ===>>RJ11 to ADSL splitter LINE port
Adsl splitter 1 MODEM port=====RJ11 to modem
......................TELEPHONE PORT ==== PHONE two way connector PORT 1 RJ11 to LANDLINE telephone
............. PORT 2 another Rj11 to Cordless
No PHONE to be connected direct to the Telephone Junction. ( each Phone can have an ADSL splitter
and connect to PHONE PORT.)
No parallel connection.

Good Morning,

I appreciate all the help

With regard to the following

TELEPHONE PORT ==== PHONE two way connector PORT 1 RJ11 to LANDLINE telephone
............. PORT 2 another Rj11 to Cordless
No PHONE to be connected direct to the Telephone Junction. ( each Phone can have an ADSL splitter
and connect to PHONE PORT.)
No parallel connection.


You mean from the ADSL splitter (the phone port),I need an RJ 11 cable to a 2 way connector (Is this looking like a ADSL splitter, but having no circuit right?, I mean one female, on one side and two females on the opposite side right?)

Now from the port 1, an RJ 11 goes to the ADSL filter, and from the "phone" port, it goes to the phone, the same process is done for the codless, port 2, to adsl, then to cordless, from port 2 right?

Please correct me if i am wrong. If this is right, how can this not be a parallel connection?

Thank you

Hi,

I managed to visualize the connection,

is this what you meant

add an http in the front

@ronferds.
Thanks for a lovely diagram .
Saves lot of problem in explaining . Have saved it for future use .
The distinction is PHONE Junction ( from ISP) and PHONE port. ( From ADSL splitter)
I meant no parallel connection from PHONE Junction.
Sometimes in a house or flat, concealed parallel telphone connections
are taken to different rooms.

Para two :
In the diagram you have posted addl ADSL splitters are NOT required.
ISP's Phone junction ==== ROOM 1 ( bedroom) ADSLsplitter 1. modem phones etc
do parallel connection = Room 2 ( Hall) ADDL splitter2 required === Phones
do ====do===== Room 3 ( Study Room ) ADSL splitter3 required.==Phone etc
http://i34.tinypic.com/s4c0me.jpg
Para two : If there is an additional junction Box ( OLD with a Female Rj11 port ) from BSNL containing some condenser/resistance/Printed circuit board) , this has to be removed, to avoid broadband signal attenuation.

Hi esbebe,

I have another diagram,

is this what u suggest me to do?

img136.imageshack.us/my.php?image=theoutlinesuggested2ax8.jpg

The 2 phones are needed, and they are beside the other, so a 2 way connector should suffice?

so no adsl splitters required for that?

i hope i make sense

These are the results of my line at the moment , on my dlink GLB 802 C

Local Tx Power: 12.1 dB
Remote Tx Power: 20.5 dB
Local Line Atten.: 32.5 dB
Remote Line Atten.: 17.5 dB
Local SNR Margin: 6.0 dB
Remote SNR Margin: 13.0 dB
Self Test: Passed
DSL Standard: ADSL2
Profile: MII
Tx Line Rate: 861 Kbps
Rx Line Rate: 10272 Kbps
Max Attainable Line Rate(Down Stream): 10336 Kbps


I had everything checked in my house, even the DP box and jointing underground. Now i assume something wrong between the exchange as well as the underground cables, something which cannot be corrected by me, or by BSNL.

Yesterday, i spoke to the Tech guy from bsnl and he mentioned something about the port, is this some sort of hardware? I mean is it in racks/cards?. will the reseting of ports increase SNR and decrease attenuation?. Can ports cause signal attenuation?

Hope am not bomarding with too many questions.

Thank you.

Rohan

img136.imageshack.us/my.php?image=theoutlinesuggested2ax8.jpg better picture.!
Yes. Also ensure no other JN Box ( BSNL) from Junction to ADSL splitter.
Para two :

DSL Standard: ADSL2

1.See whether this can be changed to GDMT. for a stable connection.
SNR must improve to at least say 10db.
2.Please post screenshot of this snr page
to compare with GLB502T/DSL502T both well documented.

Para three : After all these discussions, some one will say he formatted his Hard Disk or changed the modem, and now all are OK !
Don't do that for the present !
This is all part of the game ! Always you cannot win !

These are my observations with My Dlink GLB-802 C Modem

In ADSL mode

DSL Parameters and Status
Vendor ID:0039
Revision Number:E.37.9.48

In g.dmt mode

DSL Parameters and Status
Vendor ID:00B5GSPN

seems to have improved with GDMT Dlink router.
Try now with UTstar modem.
Report any improvement in Internet surfing.

Well esbebe,

The dlink router seems to be holding onto the g.dmt mode, its the UTSTARCOM that acts like it has amnesia after few hours and after starting it up again, it looses out on the settings.

Is the improvement seen on the "Local SNR Margin:18.0 dB and Remote SNR Margin:12.0 dB" or is SNR also known as "Local Tx power / Remote Tx power" It seems that the former has increased considerabely.

If what i assume is to be right, then its great. Do you think my line will hold. What was the problem actually? I also removed extra wire clutter near my phones, instead of the linesman's custom made connections, i followed your advice and used a 3 way connector too, looks like a small "lamba" shaped device, one female and two opposite females on the other.

Is my attenuation ok?

IF IT WORKS DON'T FIX IT "

1...Please watch for a week for stable operation.
2. ..Check speed at speedtest.net same servers say Melbourne/Mumbai.
3..... Make screen shots of settings in working condition ( for future reference )
4....... UTSTAR modem. May be the power unit/adaptor has gone bad.
............ keep it as standby.
