ando9185 Posted May 25, 2005 Posted May 25, 2005 Alright, so I've apparently got broadband!!! Yay!!! Unfortunately, I was told this last Wednesday and I'm not able to access it. I thought any problems with connections would be sorted out in the checks that all need to be done before the connections but unfortunately the only checks are between the local Telstra exchange and to the property boundary and not my flat. Pretty much my story in a nutshell is: - I live on the second (top floor) of a block of 12 flats. - There is ADSL going to the main power/phone units in the car park - Somewhere between this unit and my phone connection it is being lost. I have tried a couple of different modems, I have checked cabling and have checked the polarity of the wires inside the phone connection too. I think there may be some sort of filter somewhere in the line to only allow through voice communications. Whenever I plug in my modem, it also shorts the phone line and makes sure nothing works at all. Anybody know any information about: a) the filters how much things will cost to fix c) why plugging the modem in causes so many problems d) anything that will fix this mess!!!! Any help would be much appreciated and I would even send a thank-you email. P.S. I have already tried everything the technical support lines have suggested and had the Telstra guy round today who checked the line to the property boundary, unfortunately he didn't come inside which I would have liked and I didn't even get to talk to him (grr... I was at work and he didn't call).
John_Barber Posted May 25, 2005 Posted May 25, 2005 Alright, so I've apparently got broadband!!! Yay!!!Unfortunately, I was told this last Wednesday and I'm not able to access it. You do have the proper ADSL filter between the line coming in to your flat, and the normal phone? I inadvertently plugged a phone into the line without the ADSL phone and the ADSL modem immediately dropped out. I am sure the telecoms techo would have discussed this but thought I'd mention it. Cheers JB
ando9185 Posted May 25, 2005 Author Posted May 25, 2005 Yep, got all that sorted. Thanks John. When I set up the broadband for my parents a few months ago, before the line filter was put in, I could hear static on the phone line, which of course went once I put in the filter. With my line, I don't get any static or anything out of the ordinary on the line. (until the modem gets plugged in)
kenneth1503559512 Posted May 25, 2005 Posted May 25, 2005 All I can think of is that the internal wiring is not designed for ADSL (split pair or whatever the term is?) or that someone in the complex is using an ADSL modem without the correct filter.
gclark8 Posted May 25, 2005 Posted May 25, 2005 You may have a "pair gain" system in the building wiring..
kenneth1503559512 Posted May 25, 2005 Posted May 25, 2005 You may have a "pair gain" system in the building wiring.. <{POST_SNAPBACK}> That's what I meant (instead of split pair wiring). I knew it had "pair" in the name
mtv Posted May 25, 2005 Posted May 25, 2005 If Telstra tested & confirmed ADSL is working at the distribution frame (network boundary), then there is obviously some problem with the internal cabling/outlet or how you are trying to connect the ADSL filter.. If your normal phone works ok, you should be able use ADSL. However, as you say you can't hear the ADSL "static" on the 'unfiltered' line indicates it's not making it to your flat. Do you only have one line? I assume you already have an ADSL account on that number? (sorry, but needed to ask to be sure) What kind of outlets are there in your flat... The old cream-coloured 610 socket, or RJ sockets? How many outlets are there in your flat? What type of ADSL Filter are you using? (Manuf/model). Is it just a filter, or a filter splitter? (eg. line in with two outlets, one for ADSL & one for phone). How many and type of devices are sharing the line? eg. wired phone, cordless phone, answering machine, dial-up modem etc. Do you have ADSL filters on all the other devices too? Remember to include a wallphone if you have one. Do you have an old "bell" type phone on the line? Do you have an alarm system connected to the phone line? Has there ever been a personal medical alarm connected in your flat? Has there been an extra socket installed for a fax machine? Are you using any kind of phone 'double adaptors"? How many wires are connected in the socket, colours & pin numbers they are connected to? You say you don't hear the ADSL "static" on the line until you plug in the modem, but then your line cuts out? This tends to suggest you have a mode 3 or mode 5 wiring configuration for a fax/alarm. If this is the case, you may require an ADSL central filter installed before the cable into the mode socket, as this is the first socket in the line and performs a switching function when a plug is inserted. If you are plugging your modem and ADSL line filter into a mode socket, it would be disconnecting other devices on your line, as the modem does not loop the line back to the socket. It's possible it could just be a faulty termination in your cabling, which won't pass the high frequency data signal. As Telstra have probably already told you, they are only responsible for service provision up to the network boundary (which in a house is the first socket where the lead-in terminates, or in your case, the Building Distribution Frame.) Any cabling past that point is the respsonibility of the owner, so you may need to have the agent/landlord contact an ACA licensed/registered cabler to inspect this. See how we go with some answers to my questions first Cheers Col
mtv Posted May 25, 2005 Posted May 25, 2005 You may have a "pair gain" system in the building wiring.. <{POST_SNAPBACK}> That was also a thought I had, however Telstra should have it on their records, when they did the initial ADSL connection order and also when they did the fault report. But, it wouldn't be the first time they have overlooked something
pauldwcarroll Posted May 25, 2005 Posted May 25, 2005 Hi all, great reply mtv, you must be a tech like myself. To highlight a point, if telstra, or your adsl provider has said that adsl is available to your units main address and the tech could sync a modem at the building main frame, if the cabling to your unit is straight, ie: a twisted pair copper cable or cat-5 cable that is not in multiple with anyone else, or going through a pabx your adsl has to work to the first socket, as long as there is no other equipment connected. Cheers, Paul in Fat Cat city.
bamboo Posted May 26, 2005 Posted May 26, 2005 also might want to ask strata on the line installation which they are responsible for.
ando9185 Posted May 26, 2005 Author Posted May 26, 2005 Ok, thanks for all the responses has been great! I've talked to some blokes here at work (I work in an electronics lab) and luckily one of them has all the qualifications, we're going to my place at lunch to have a quick look and see what we can find. Thanks mtv for the detailed response and here are some answers. Cheers guys. It's very much appreciated! Do you only have one line? yesI assume you already have an ADSL account on that number? (sorry, but needed to ask to be sure) yes What kind of outlets are there in your flat? 610 going to an RJ11 on the phone and RJ45 on the modem (and no, that's not for LAN) What type of ADSL Filter are you using? I think it's dynalink, just an ADSL micro filter (1 output for phone) How many and type of devices are sharing the line? 1 wired phone and 1 broadband modem (dial up modem when broadband isn't working) Do you have an alarm system connected to the phone line? no Has there ever been a personal medical alarm connected in your flat? not that I know of, but I highly doubt it Has there been an extra socket installed for a fax machine? no Are you using any kind of phone 'double adaptors"? yes, but same results without it How many wires are connected in the socket, colours & pin numbers they are connected to? 4 wires (red, black, blue, white) but only blue (pin 6 i think) and white (pin 2 i think) are connected (not here to check) You say you don't hear the ADSL "static" on the line until you plug in the modem, but then your line cuts out? I haven't been able to hear the 'static' at all, ever. <{POST_SNAPBACK}>
ando9185 Posted May 26, 2005 Author Posted May 26, 2005 OK, so things are looking better now. I'll probably do some more testing on Saturday when I have some light and it's not so cold or windy! A few points I found today: - No matter which pair of wires we tried, the same result all the way. - It appears to be straight through wiring, although it is difficult to see as most of it's behind brick walls! - Now for the big one! We found which wires connected my phone to the network boundary and added a couple of alligator clips and my phone to it. The result - a dial tone but no static. I'll have to check some more to test this theory but it would explain a lot. I should also add that we found out which connections were mine in the network boundary by the log book found in the cabinet and by checking voltage levels when the phone is on or off the hook.
mtv Posted May 26, 2005 Posted May 26, 2005 Sometimes you can't always hear the ADSL data, when the modem isn't online. Be interesting to see what you find with a better look.
