    The wiring is so badly done, and left all open and BSNL is supposed to be a government owned isp....its not good enough.

    Have you asked them to check the wiring for you?

    The best thing to do is complain to BSNL and ask them to sort this problem out as its been a month, you have to complain at least 5-6 times before they would actually do something. If even after that they don't do anything I suggest you choose another broadband provider.

    I complained more than 10 times,every time i write the complaint in the complaint register there would be a call from bsnl dept. the following day, once i attend the call they wont ask anything just say hello and they'd cut the call meaning the phone line is not dead and close the complaint am so frustrated and pissed by bsnl and i cant choose any other ISP because there is none here

    Your line quality is such that I am surprised you are able to connect even for 5 mins. There is nothing you can do at your end as it is BSNL's domain. Go down to your local Bsnl office and put up a complaint in writing and get receipt for it. Talk to the PRO if possible and see if that helps.

    If I was you I would rather bet some other company's connection after all that.

    Here is a thread you should have a look at : SNR Margin FAQ

    Seriously man so fed up with bsnl, and when i found a way to connect to the main line that goes into the distribution box what i got at SNR margin for down stream was at 6.5 and upstream was 25 what is that mean anyway "upstream snr higher than downstream?" beside am wired with electrical wire rather than telephone wire...from the distribution box.

    That could be another reason why your line quality is so bad. Why do you have an electrical cable instead of a telephone cable?

    Well, when the house was built every thing was pre wired by wire man including phone junction's and phone face plates may he doesn't know the importance of how bad electrical wire when used with telephone wire, so when i got the new connection the bsnl line man came and simply connected telephone cable from distribution board to the electrical wire that has a lead from bottom of the house and i found that there like 5-6 junctions and none of them are connected each other by coupler or splitter their just joint each other by insulation tape...and i found that telephone cable [issued by Govt.]has two single copper wire each separated by a thin fibre like material but the electrical line has thick copper i think it can even handle 10-15 amp current..so imagine the thickness!!

    Dear Johnraga,

    i suggest you to lay down new wiring from BSNL junction BOX to your home end splitter use DIGI Link CAT6 (100M BOX Rs.1780) Cable it will definitely improve your SNR and line quality. BSNL and MTNL use worst quality of Copper wire with lowest bidding tender ghoookhooor. I'm also MTNL LandLine user not broadband there is no static sound humming nothing

    Thank for the advice mate but am unclear of the info the bsnl has only a pair of copper but the digi link seem to have 5 paired wire, how would i make the connection ? like two twisted wire connect to one copper wire? and am amazed with phone's quality there is no humming or any static its crystal clear only the broadband suffers with low snr...TY

    guys i found that when i tried with one of my friends modem that is Tp-link TD-8817 the snr have got significantly boosted so much tplink.jpg and having a solid stable connection with not a single disconnect, so this leaves me a question that is my modem Asus DSL-10e is malfunctioning or snr is relative to type of modems features and in the image you can see the upstream is only 10 is it ok? or it should be over 25? and am still on electrical telephone lining...

    To the best of my knowledge SNR is not dependent on the modem you use. Before getting to the conclusion that your modem has gone bad, can you try using it at your friends place and see if shows considerable lower snr there as well as compared to the other modem? If it does then I guess it is time to go shopping for a new modem

    hi,I did as you advised and it seems the modem is faulty it doesnt even show the dsl statistics, shows everything as zero... so ordered TP-LINK TD-8816A at flipkart.

    Changing your modem can not improve your speed quality and stability in link with DSLAM. From your DP box use copper cable provided by BSNL or use CAT 6 cable. Problem arise stability of connection if use electrical cable.

    CAT 6 ? u mean the Ethernet wire but the density off copper in it is lighter than provided by bsnl is that ok? if cat 6 can do the job i don't have to be dependent on Bsnl or line man, any ways the line from DSLAM to dp box uses wire similar to Ethernet cable,but the connection comes directly to my home its joint with my line it doesn't go and connect the dp box..Thanks for the tip,ill do it myself tomorrow..

    If your modem is not working even at your friends place then does it not mean it is faulty? However you could try resetting it to factory settings by using the small hidden button at the bottom and set it up again and see if that gets it going. Also you could try checking if a new driver is available for your modem.

    Electric cable from the box to your house is not adviseble. I know this for a fact that it will deteriorate your line quality.

    It does prove that your modem has gone bad. Get a new one Also use a proper telephone cable to connect from the box please.

    Dude, first of all, check out the cable coming to your home from the DP (Distribution Point) of BSNL. This is generally outside the building, maybe at a nearby road junction. This cable should be jointless, i.e. one-piece till your home, from there on, it should be a pair of 1/18 (single core 18 swg) gauge wires which is generally used for electric fittings in any household, to the point of your modem's wall RJ11 jack. this cable within the fitting of your home should be jointless as well. Now we come the the cable that runs from the wall jack to your modem. It should be less than 6 feet in length, no joints, and should be of good quality. it should end in a DSL filter, which gives off one connection for the telephone and one for the modem. This filter may be put into the wall jack and then a cable(off less than 6 feet) from that may run to your modem, while a cable of any length may be run to your phone. (Logical, isn't it?)

    If you check out these points, and apply even half of them, then your SNR will improve drastically.

    CAT6 density off copper dose not lighter than provided by bsnl. The link you provided it has CAT6 wire with RJ45 connected, you need without RJ45 cable. Use only twisted pair of the CAT6 for connecting. Their is a four point with pair. Use one pair.

    Ok guys ive managed to get some items for my own setup
    1.Frontech CAT 5e 4 pair gigabit UTP[ at least whats written on the cable] frontech cat 5e.jpg Picture 40.jpg
    2.Bsnl Faceplate [2nos if in case] Picture 36.jpg
    3.An ADSL Filter Picture 41.jpg
    now the setup i used, but failed
    ive cut the sheath of two twisted paired wires[white with brown & white with blue]Picture 38.jpg and screw 'em up with A,B on the faceplate brown white.jpg
    and did the same thing on the other end and joined with the line that goes to DP Picture 37.jpg[look a like what i did outside, the cable in image is the govt laid]
    and connected the landline to the faceplate Picture 43.jpg but no dial tone, also ive used each twisted pair but its all big fail have no idea what's gone wrong, but when i used the bsnl provided segment of line with faceplate and connected the landline it worked flawlessly Picture 44.jpgPicture 45.jpg[belonged to my friend] so pls tell me what did i do wrong here...and enlighten me get it workin i know its that simple but am all frustrated badly and couldnt get it to work..BIG Thanks to all who has replied for the solutions

    Dude the line which comes to my house is joint with the line that goes inside the DP.

    So, there are 3 joints from your modem to the DP? but which cable? Your target is to reduce the number of joints from your modem to the DP as much as possible. Even the Telephone box and a splitter are considered as joints. The number of joints should be as close to 3 as possible. DP to BSNL cable = 1st joint, BSNL cable to phone jack in house = 2nd joint, splitter between modem and phone = 3rd joint. These 3 cannot be avoided. Any more joints, and thinner cables will compromise your SNR and line attenuation.
    Since the BSNL cable has a thicker copper core, it will NOT absorb more electrical noise. In case the cable is thinner one running in the walls till ur modem, replace it with the one similar to the BSNL cable.
    Just FYI, BSNL cable is generally a black coloured cable, with a fibreglass center and 2 copper wires running on either side of this center.

    No dial tone means some problem in your cat 5 cable or the point where you connect to the faceplate. As given picture shows that BSNL cable come to your house then you don't need to add cat 5 cable or cat 6 cable from that BSNL cable's end point. Because it will add more length and create resistance. You have been told to connect that cat 5 or cat 6 cable to the end of that BSNL cable which is from your DP box. First connect you modem at this point of BSNL cable Picture 45.jpg and see what result you get. If you get the same result as previous then there could be problem with that BSNL cable. So we suggested you to connect that cat cable from that DB box to your home. But remember we assume where could be the fault but we can not give you the assurity.

    NB- From that DP box mean the end point of the cable provided by BSNL which is connect outside of your home.

    actually there are 8 joints including splitter with pre electrical wiring, as of now am going to give it a try with Ethernet cable there should be only three joints including splitter and telephone faceplate and one with the line to dp box, Damn those Bsnl guys they wont sell the cable or give me extra till my room like [40 mts from dp box] tried all the electrcal store but couldn't get one like bsnl all single cooper cables are either Tin coated or ver light in diameter

    thats actually not my cable dude, its a borrowed one there is no bsnl cable to my house it just electrical line connected to bsnl cable which is also connected to dp box wire...if i connect the modem directly to the dp box with small patch bsnl cable it works fine but with CAT 5 it wont or no dialtone, i suspect there could be break or discontinuity in-between the end points ,have no multimeter to do a continuity check ..

    Guys finally bsnl line man showed up with bsnl original cable, but had to bribe for 400 buck in the name of cable cost but anyway the problem is fixedgood snr.jpg snr values on both sides have drastically improved and am having much stable connection than before...had to lay a 25M wire with two joints..Thanks to all for the info & support , now to face the second problem that's lifting the speed cap for my 4Mb/s no idea how long or how bad this is going to be .....

    Well, Congrats! Now that the number of joints have reduced, the speed cap can be improved by improving the quality of the cable used herein. It is also dependent upon the Loop Length, i.e. the distance from the BSNL exchange (called as Central Office) to the first joint / wall jack in your home. This distance is actually the cable length from the Central Office to your home, and not the actual distance along line of sight. So, the farther you are from the CO, the lesser speed you will get. However, between 1-2 kilometers, 8 MBPS should be possible.

    Here's a secret. If BSNL cannot improve this, ask the dude from BSNL to change the jumpers in their exchange. If that does not work, ask him to move the jumpers to another free (circuit)card. Should work wonders for you. However, do this only as a last resort, since they will expect bribes for this work.

    i hope the loop length must be less than 1 km i say this coz there was a telephone digging where they were laying huge cables from exchange to Dslam, the cable was short but its a trench line from Dslam to my home is a elevated line using telephone poles i think its CAT-6 cable it should be around 200-250mts, and regarding speed cap removal whom should i ask can a line man do those jumper configurations? now a days bribes becoming mandatory in other names so np abt that...Thank you

    The linemen travel in pairs. A lineman (who might be a trained engineer) and a "jointer". The lineman is the senior of the two and expects more bribes. The "jointer" on the other hand, will be able to do the same work and expect less.
