    Experts please help me to fix this issue, i suffered from same issue before so many times, but everytime BSNL guys came n re-joint the cutpoints & went. (If anymore info needed ask here, i will post.)

    You may have to talk to that Sub Divisional Officer (SDO) Phones and request for a copper pair change and end leads replacement.

    Only after that a stable performance can be expected. All the best.

    If you have access to your BSNL connection box then please look at the connections yourself. Make sure that they are well twisted (if not punched down, which they shoudl be, but they don't seem to bother) and physically separate from each other and from anything else that could short them out, which includes even plastic, if it gets wet.

    Spray them with something like WD40 for moisture resistance, or tape them. Wear shoes: there is not much voltage on a telephone line, but there is enough to feel it if you have bare feet (learned the hard and tingly way).

    Some time, I intend to put heat-shrink sleeves over my connections, but I don't know where to buy the sleeves. I hope this would put an end to the periodic cutting, stripping and re-twisting that they otherwise seem to need.

    If this does not help, then water is getting in somewhere else in the circuit and only BSNL can help as per mvs sharma's post. It could be anywhere between the exchange and your wall socket.

    only two connections r thr.. i taped them before.. but teh lines-man came n say tht dont tape them.. may be connections are short.. so he open the tape & re-joint the wire.. he did with both cut points.. joint with tape differntly..

    Only two connections is correct.

    Just make sure they cannot short, as already suggested.

    Change to GDMT. ( now showing Adsl2 +)
    Your modem GLB802C?

    You can add another RJ11 Port ( No shaking effort !!!)
    ( IF BSNL has supplied a Box confirm )and use rj11 cable with connectors at either end.

    yes i use glb802c.

    u showing the img. is over street. means thts in between telephone poster & home.

    line> adsl splitter > 1. to phone & another to modem.

    currently using direct.. means. line>modem

    Default Dlink GLB802C

    whether you are using the phone or not for line matching,
    ADSL splitter MUST be used for the phone. ( AC & D.C voltage present )
    Even when you use the ADSL splitter the modem is Directly connected to BSNL Phone line.
    With above set up if you hear a "Hiss" noise( when Internet is connected ) in Phone means ADSL Splitter Filter circuit is faulty/shorted..

    Confirm you dont have an additional RJ11 Phone Box provided by BSNL.
    ( Some PCB with lightning arrestor circuit may degrade DATA signal )

    Any improvement in SNR ATTN after changing over to GDMT ?
    Even 1 or 2 dB increase in SNR margin makes a difference.
    The joints , if polished and twisted and taped, should not affect
    for "shaking effort" !!
    The wires tend to get rusted/blackened/oxidised to exposure to air.
    becoming a high resistance joint.

    i disconnectd receiver today. no other connector between splitter & line.. direct line comes to splitter & then to modem. as i told remove the splitter now the direct lines come to modem. No Hiss (Noise) after lines man check the cut points & rejoint them.

    Last ADSL2+

    not sure if related but I'm getting atrocious packet loss since yesterday (6/16).

    if there are no breaks on your line it's probably on bsnl's end.

    Seems some improvement with GDMT.
    Can you please try with a different modem? even though line is suspect.

    m damn sure about modem.. its in well mode :P bsnl guys says these.. widout checking their side "You modem is faulty" :|

    so finally i chng the line wire direction i mean in diffrnt path not between trees.. got some improvement.. m not sure though may also be caused by weather.. its lil clear now..

    LoL
    please request them and your work would be sorted out. Low insulation of underground cables, and dry joints in end leads would the reason. there is a lot in cable pair conditioning for ISDN and Broadband, perhaps not possible to explain here.

    OK. BSNL is buying only these models based on Siemens board.
    Their staff may not be familiar with routers D/link/Linksys/Netgear/Buffalo etc .
    If you have this unit on rent anytime it can be exchanged. ( free of cost)
    Was this attention due to On line complaint ?
    Best of luck.

    i had also faced the same problem, make an email to cmdbsnl@bsnl.in describing in short about your problem. ask the local line man( if they dnt hear pay some bucks, they will) to change the cable pair and put copper insulated drop wire to your home from the DP box , make sure that they dnt use insulated GI wires( these wires have high attenuation than copper). Also give importance that the lines are not grounded even with high resistance , minor grounding of wires also causes the ADSL link to go down frequently.

    I was also having the same issue...bb was not woking for past 1 week...link comes for 4-5 mins. then wosh..its gone..so today i called my electrician and told him to check the phone line...he connected the telephone set...we can here some disturbance on handset....he dismantled all the wires and connected them again properly...disturbance sound was gone and bb worked well...after 2 hrs of using, rain started pouring...it got disconnected but after 2-3 min. link came back again and is working fine...but i think i have to get wires changed as i have been using these for bb for past 6yrs...now they r giving me problem...

    Water usually enters the old cables through joints and initialize 2 things.
    1. makes the line pair earthed thereby dropping voltage at the

    2. makes audible noise and also of higher frequency which is the culprit of eating most of the ADSL tones.

    Better change the line ,or if possible drag a new UG cable to your home

    are you telling about the Phone line or ethernet cable ?

    Phone lines are generally Under ground and contains jelly with minimum 5 pairs of small copper wire of different colors, where ethernet cable doesn't contain any jelly and used for only high speed data transmission .

    are u using DSL ?

    it must be a copper wire ( not so thin, which add resitance and hence attenuation) , the 2 wires should not be twisted upon itself,

    Better u can use dropped wire ( small flat black wire which contains 2 copper wires on each side of a centrally placed plastic fibers to withstand pull force)

    As BSNL office to get new drop wires .

    @arpit20one

    Just try this:
    The two wires coming to the BSNL junction box.
    Say yellow and green. It will be connected to
    to Rj11 port. Just reverse the wires .!
    (AC + DC voltage.present !!)
    If you touch one wire you may get a MILD SHOCK!!

    Sometimes this improves BB . No guarantee !!!
    @anupam8

    Wear rubber-soled shoes.

    The first time I tried handling these wires bare-foot I was ... shocked!

    Ya the DC voltage is around 48 volt in normal mode and the AC voltage while ringing is around 100 volt, so beware that the phone line is not passing any ring current
