PTCL DSL Router Reset with Calls Even with a Splitter HELP PLEASE!

[gphantom]

I'll put this in brief,

6-7 months ago I installed a splitter on my PTCL line and everything worked perfect. Router would not reset with any kind of calls and there was no noise in the phonesets either.

BUT until after like 3-4 months, I started getting disconnects all over again, and so the first thing that came into my mind was - "yes it could be the splitter expiring". SO I went to the PTCL office and they gave me a new splitter sealed in its plastic cover, guaranteeing that its NEW.

I replaced the old splitter with this new one but the problem still persisted. Which lead me to the next thought that - if the splitter is okay, then it must be the MAIN-LINE cut somewhere before i've put it in the splitter. But I checked that too!! I traced the WHOLE LINE back to the pole where it comes out of that PTCL BOX, with not a single joint! and now I'm wondering - What else is there that might be causing this?!

I cannot describe what agony this issue has caused for over 4 months now, and the PTCL staff? PTCL LINE support says its a DSL STAFF issue, and the DSL Staff says its a PTCL LINE issue. I am bound to fixing this on my own here now that I'm out of options.

As a gamer I'm sure you realize how painful it is when you get a router reset during a game, specially in clanwars and serious matches etc. Hours of entertainment turns into hours of agony and a waste of time completely.

Please suggest something, what else should I do to fix this issue. I cut all the old connections and made fresh ones to confirm that it is not the wired wearing out, and I also changed the Modulation in the DSL ROuter to G.Dmt but it doesnt help...I am totally disappointed at the moment with all what PTCL is doing, Extra BB charges and if you want to downgrade to 2mb, 1218 has COMPLETELY ignored all phone calls, and would NEVER pick up, I waited 55minutes on the line and they won't respond because they are obviously earning a huge amount of HARAM with this UNFAIR charges, and I would seriously cry to how PITIFUL this situation is, looting people just because there is no other BroadBand service feasible out there. I'll keep my sadness for another topic then but for now I would love to fix this Disconnection issue.

Thank you

Firstly, a NEW splitter does not guarantee that it's working fine. A new one can be faulty as well.

Anyhow, I'd advice you to remove the splitter between your router and the telephone line and keep the splitter for the phone only. So if your previous configuration was:

PhoneLine->ADSLFilter->Router
PhoneLine->ADSLFilter->Phone

Change it to:

PhoneLine->Router
PhoneLine->ADSLFilter->Phone

The ADSLFilter that is used by PTCL and other ISPs here serves two purposes, "signal splitting" and "filtering". The filter bit of these devices is mostly not implemented correctly and the reason why you hear white noise in your Phone when the DSL is working.

If you don't understand the config I mentioned above, post again.

I m having the exact same issue and have been pulling my hair out over it . Ptcl support is a pain as usual. I ll try to see whether puttung a fulter only on the phone makes any difference.

Thank you so much for that,

Although I'm not going to try this right now because I'm currently experimenting with another idea. The dilemma is that the router will not reset every time with picking up the phoneset, but still resets at other times. This is confusing. How can I confirm if the splitter really is working and the DC is from the Server?

Because after I renewed the wiring I picked up the phone and router reset, but now that I tried that again it did not reset. Could it be the change to G.Dmt? and could that earlier phonepicking and router reset merely be a coincidence? I'll wait to confirm this and if it really is a problem with the phone then I would gladly try what you suggested.

So does the splitter only remove the DSL data from the line? I mean, for me as a layman, I would prefer putting the splitter to the Router and not to the PhoneSets as you speak. So how does this work?

Once again I'm grateful for your concern. God Bless you.

G.DMT is an interleaved data transfer protocol unlike ADSL2 or ADSL2+, both of which use fast paths or non interleaved datagrams. It just means that G.DMT/Interleaved protocols can handle noise spikes in your phone line, while fastpath protocols can't to a certain extent.

A typical analog telephone set uses a "5v blank" line charge when you put down or pick up the receiver. The charge/break tells the exchange that you reset the line. However, this charge is also the cause of a large noise spike in the line. If this noise spike is not handled, the ADSL/digital packets get jumbled up and your router/filter does not know how to handle that much disturbance, thus they drop. G.DMT on the other hand tries to handle that noise spike.

This means that the cause of noise is "always" the telephone/filter or the telephone line itself (electric/static noise around the line or in your vicinity).

When you turn on G.DMT, you turn on Interleaved datapaths, which allows for error correction of any errors that occur because of noise before sending the data to the ISP. So, your line won't drop but your ping will increase because the router is constantly trying to correct errors.

You can read more on the technical stuff online but I hope this much helps you understand the concept.

All (99%) of PTCL's connections are already set to interleaved datapath on any modulation, G.DMT, ADSL2 & ADSL2+. Its a company policy due to the old line infrastructure.

 

[mhaqs]

^StrikerX, that was the policy of Dancom (now LDN). PTCL has an adaptive layer for that. If you use ADSL2+, you'll be on a fastpath. If you want ask PTCL support, they can put you on a permanent interleaved path as well.

I don't know if I've done this right,

But soon as I did that, I got two DCs in 5 minutes, without any apparent reason like phone calls etc.

Any suggestions for the settings bellow:

 

[mhaqs]

Please post your Modem stats, they should be in the system page.

PTCL's new MSAG network is adaptive, all others are on interleaved. That is what my friend said, he is a PTCL core manager.

I'm not sure if these are the stats but this was the only thing I could find relevant to Modem Statistics.

That is good information StrikerX. Thanks .

Your stats are good for a 4mbit line but if I remember correctly, PTCL's Downstream minimum SNR limit for a 4mbit line is 12db and if your line goes below that, your line will drop. If the current configuration doesn't hold for you, try to get a better ADSL filter.

 

[StrikerX]

^
Nah its not 12db. This guy's line is adapting according to line parameters, at first sync it fails to sync at the port set by PTCL which I am assuming is 4096 or 4614 so after failing at first sync DSLAM & modem try to sync at the best possible rate in the current line parameters (maintaining a minimum 9db SNR).

@OP
Looking at your current line stats, the problem is your line/pair. Get the lineman to fix your line/pair and or you can change your package to 2mbps so that they set your port to 2048 or 2556. This will probably solve all your problems.

No biggie

 

[mhaqs]

If it's 9db then they may have reduced it. It used to be 12. Anyhow, StrikerX, you sound like PTCL support there, no offense, lol.

The ADSL or G,DMT loop puts lesser strain while ADSL2+ doubles the bandwidth but puts a lot of strain on the line. We're talking about a drop of around 3-6db of SNR when you go to ADSL2+. Most PTCL subscribers are limited to 4mbit, thus it makes no sense to use ADSL2 or ADSL2+ as a modulation. G.DMT can go to 8mbits without any threshold increase and its wiser to get the margin gain. Meaning that any ADSL loop places a load on the DSL signal, and the longer the DSL loop the more the stress. The additional stress on the copper line is a factor of the current passing through it and ADSL2+ places additional cons above the G.DMT (ADSL) cutoff. To make up for this stress, the power is reduced, and due to this reduction, if the loop goes over 8-10 Km, non-bonded ADSL2 can have a lower thru-put than standard ADSL.

I know all of that might not make sense to everyone but DSL comes with that trade off. People who shift from 4mbit to 2mbit trade for the increase in power and reduction in bandwidth, thus resulting in increased SNR and lesser drops. This has everything to do with how much load (distortion, echo, noise) there is on the PTCL network. One would get more disconnections at specific times of the day.

Anyhow, @OP since PTCL won't be helping you a lot technically with this issue, and changing hardware/pairs doesn't help. Dropping your package from 4mbit to 2mbit is your last option.

 

[gphantom]

Thank you guys for all your support. I would love to get a downgrade from 4mb to 2mb but PTCL Service won't pick up. So I suppose I'll go with the first option you gave me. You said,

"Get the lineman to fix your line/pair"

But How do I convey this issue to a lineman? I mean he would ask for a problem and I don't know how to explain this to a layman. Is there another terminology for this? I live about 300 meters away from the Exchange Office and the wire that comes from the pole is not more than 20 - 30 meters from our home. Where does he need to look at? the box in the pole? or is it something that needs fixing from the exchange office?

Thanks again

I would SERIOUSLY love that. But I have NO reference in PTCL and if you have ANYONE, please, for the love of God downgrade it for me. I know its their scheme to get maximum earning and ignore incoming calls for downgrades, but for over 3 months? Please.

People download over 200GB with just 2MB connections, yet 4mb has mere 40-50GB limit. This is absolutely PITIFUL. Why would we need a faster connection when both has the same response time? This is utterly ridiculous!

So if you have any reference please help me out.

God bless you.

Lol well I've had a lot of experience with PTCL (good and bad both) & my friend who works at PTCL core always talks about the 'technical' stuff so I catch on xD

That might or might not work because if they leave his port as it is i.e 4mbps but change his username's speed from 4mbps to 2mbps (they implemented this few months ago & its partially working) than OP will be where he first started, no change at all.


@OP
Tell the lineman to check your line & renew joints (if any) & renew the pair from DP (Distribution Point), if the pair is weak than tell him to put you on a new or a better one (Lineman knows which is good or bad).
Tell me the main wire goes directly into the splitter or it comes into the home wiring & you than take a wire from the socket to splitter & so on? & where are you from?

 

[mhaqs]

StrikerX is right, it all rolls down to the lineman eventually, they know how to get things working correctly. It's a pity there is near to no sync between the linemen and DSL staff.

About getting your PTCL package downgraded, I have had some issues getting to a senior support exec at PTCL support. But if I tell them what's wrong with my line, the next morning it's fixed. It's hard to get to a senior exec though . Try your lineman first, as StrikerX said. If your lineman refuses to help you (some of them can be a PITA), try your luck with DSL staff or your local exchange senior staff. Getting the local exchange execs to intervene in certain tasks has always helped me.

 

[gphantom]

Tell me the main wire goes directly into the splitter or it comes into the home wiring & you than take a wire from the socket to splitter & so on? & where are you from?

It comes directly into this transforming socket into a soft wire that goes into the splitter, and then splits into two wires which again go through this transforming socket from soft wires to hard wires, where the phone line goes throughout the house and the modem wire goes straight into the modem.

What concerns me is that, it worked for over 4 months, but without a sign started disconnecting with calls again. So I change the splitter with a new one yet the problem persisted.

PS> I'm from University Town, Peshawar

 

[StrikerX]

@mhaqs
Yup that works as well. Try getting in touch with the assistant manager MM & BB or SDO or DE. Directly approach them, don't call em.

@OP
Peshawar hmm... sorry I don't have any contacts there :/

 

[mhaqs]

@OP, with your current setup, when the DSL is up, pick up your phone and listen to the tone correctly. If you hear static or white noise, then it means the ADSL filter is not working. You'll have to keep trying things until PTCL officially helps you out because if the problem is outside your premises, there's nothing you can do.
