Plz suggest am too confused

UT-300R2U ADSL MODEM MENU
see this website. modem Hardware board is same as beetel 110Bx1.
see the first link and check how how you have connected the phones.
No parallel connection from Phone Junction to other rooms.
Use additional adsl splitters for phones.
You could have interchanged PHONE and LINE connections.

Open modem and report Mod selected SNR Attn Line speed data
( see under Statistics ADSL ) .
screen shot if posssible. as Jpg annexure.

Checked the conections they are same ... there is no parallel phone just aa single phone that too after splitter (if connected) and these are the screen shots
Am tryin too upload files but it is not uploading taking a lot of time so

When direct connected the Snr are 9.1 and 8.0
Atn is 29.5 and 15
status is showtime

Wehen splitter is attached all are blank and status is Down

Thanks for JPG picture.
Please edit and delete the bmp picture.
Probably the Moderm port connection is
corroded/blackened /oxidised/ high resistance
contact etc.
Open circuit suspected.
Inspect the unit and replace.

But are you considering the fact that it works perfectly with out a splitter.... I am very much confused about this...and thnx for the immediate response

see the inside of an ADSL splitter.
Connection to Modem port Rj11 is straight through.

Well this circuit diagram creates more doubts as to why it doesn't work but i guess i have to check the modem now ....

Am sorry this may look like a dumb question from my side but looking at the PCB inside of two splitter boxes both the phone and ADSL pins i.e each of the two pins are shorted I have attached a small jpeg i tried to tell my observation can u clear this to me Thnx

THis is the small block diagram

well drawn picture. congratulations.

Whatever you do NO FILTERs from
PHone Junction to modem input port Rj11
( In any other room Parallel Phone connection
use additional ADSL splitter/s for the phone )

option 1 :
YOUR BB signal is fully blocked by the filter circuit !
Now use this to connect your phones .
two of them ! modem port and Phone port !
Connect direct to Phone Junction the modem .

Option 2.
Get a new ADSL splitter. ( from electronic/computer shops)
Cost . about Rs 50/=
Option 3:
Use a two way PHONE splitter to main Phone junction.
One to defective ADSL splitter.
Another to modem .
Problem should be solved.

shirish_kal

Thnx for the reply I guess i am gonna go for option 2 coz that looks simpler and i was not able to understand option 1 ...sorry i am technically a bit dumb

But how could beetel do such a mistake if the fiter circuit in splitter does block BB signals and i have checked 2 splitter box's with same connection..

At the same time can you suggest me any particular makes splitter Thnx

panchabhut

get a new splitter. should not cost more than 60/-.
I had exactly the same problem. things are back to normal after changing the splitter.

You are modest. My regards to you.
None would have taken the trouble to open the box and
compare the schematic diagram with actual printed board
etching, and drawn a nice diagram to top it all.

REP+++ given. ( please confirm how many points were added . [Check userCP visited threads bottom ])
for locating fault in ADSL splitter.
BB signals almost blocked because of this fault in PCB.

Para two;
ADSL splitter : supplied by BSNL
China make FUNJIN. white color
Try to exchange at your Telephone Exchange,
if not easily available. in your place.
Another one I have , is marked "Ut300" black.
no other details.

Please give feedback on the problem.
solved or not.

shirish_kal

i have 19 points in total

And i will reply as soon as I get a new splitter

shirish_kal

Well here we go... Just as i said earlier I am dumb but the worst I am dumbest well jokes apart I made the mistake that I assumed one side of splitter to be Input and other as Output So even after repeatedly viewing the splitter box I couldn't make out what was I doing well. I was mistaking Line for phone and Phone as Line because of its location I am adding the JPG to see what mistake I was doing.

Well Finally the BSNL guy came and told me my mistake now its working absolutely fine

Thanks for all the Inputs and suggestions guyz

Your picture seems incorrect
even earlier in the thread I missed the point )
India Broadband Forum
ShowsParallel connection AFTER the Condenser/coils. for PHONE and Modem.

Nothing should be there to attenuate/Reduce
the BB signals from Bsnl Phone junction
NO filter required for ADSL PORT.
