The VDSL Modem

I understand that with the FTTH Modem it converts the light to electrical signals.
But why do we need the FTTC Modem I thought the signals convert at the cabinet?
Experiment:
And what if someone tried plugging the Home Hub 3.0 straight into the master socket with the RJ11 Cable, with BT Infinity what would happen? 

Because it needs to Modulate and Demodulate the DSL signal that is provided from the cabinet equipment. Essential all that has been done is the exchange equipment that provides regular ADSL broadband has been moved to the cabinet (different being VDSL).

  • VDSL modem in sync, HH3 and HH2v2 power cycles int...

    Dear All, Firstly this is my first post on the forums so hello to all. On to my topic, A friend of mine has a very very interesting FTTC fault. The VDSL modem is in sync, but the HH3 from 3 blue lights, will suddenly shut off and restart. This happens any ware between every 10-45 mins. Here is the fun bit: Engineers have replaced the modem and the HH3 3 times. They have even tried a HH2 infinity router which lasted longer than the 3 but to no avail. The modem and Router are both plugged into a surge protector. They have both been tried on regular sockets. The VDSL modem is always happy, in sync but the routers are being power cycled. There is no line issues, no CRCs as the engineers have said. The speeds to the VDSL modem are all fine, and the speed of the BB is working fine, its just the random power cycling of the routers that has everyone stumped. Yes its been turned off and on Yes its all plugged in Yes all cables have been tried and tested One Ethernet device, other wireless laptops There is no trigger, weather simple MSN text or HD streaming there seems to be no trigger as such for the router So tech guys, i would not bother you with a simple one, here is the mystery, whats the theory's?

    After a worrying start very nice replies thanks guys! so firstly
    @ HH replacements he had one, BT sent him one and the engineer used one. I know for a fact these are all from different batches.
    @ channel changing Not only would the amount of random channels the smart wireless would have been using with the ammount of swaps, the engineer set the wireless channel whilst doing interrogations on the router.
    @ electircal supply Here was the ebst bit, the engineer knows about REIN (f Repetitive Electrical Impulse Noise). In the room with the router there are LOTS of powerboards and power adaptors link multiple supplys. There are pets, a pc, standard sky tv boxs and relavant go withs. SO yeah lots of stuff. The uncle is a sparky, checked the house and said all good. We have a UPS (i think thats what it is called) which can deliver a constant voltage no matter what, even from that it was going fine then boom power cycle.
    Feed back from 12 hour obs: The HH2 apparently has made it much more berable, taking around an hour or more till it resets. Engineer came round and did a lift and shift to get a new port from the dslam. At that point the engineer had been told he had to leave, but he justified it. There was nothing else that they can do, port, line, socket, HH modem have all been eliminated from the enquiery.
    At this point the router had been moved by the enginner to the best poisbble location in the lounge for it to not be near a source of potential REIN. Then he told us that he wanted to find out what the problem was because it was a "mystery" and he was interested. He told about REIN and how to test for it (AKA long time of having not a lot plugged in and before anyone got mad (and lets be real this guy was not just going to come over and say "sorry man we don't know how to fix this" ) he also advised us to talk to our Service provide (aka BTR ) and to tell them what the issues are. So what do people think of this ?

  • VDSL Modem issues

    I have had Infinity for about two years and it has been solid - until about three months ago when I started losing access. Firstly about once per week, now up to two or three times a day. Each time the vDSL modem needs a restart (not the HH or Router) and everything is the OK. Sometimes the DSL light goes off on the modem when the problem occurs, sometimes not.
    It is possible to retrieve logs from the vDSL modem? Any other issues I should be looking for?
    My PC and devices are both wired and wireless, but it is connectivity from the modem to the cabinet that is lost, not connectivity from the devices to the router.

  • Enabling dhcp on the openreach vdsl modem possible...

    good evening all!
    just had my infinity installation done and its really great. if anyone has read my other post a week ago about my questions of using powerline adapter to connect the modem to the homehub, the answer is YES! Much to my delight (and that of the engineer who said he didnt think it would work) it does work . i have the modem connected to the master socket downstairs and then upstairs in the loft we have the homehub.
    there is one problem. it appears that any other powerline adapter i connect (say for example to connect another pc) this doesnt work. i think this is because the openreach modem has dhcp disabled. does anyone know how to access the settings of the modem to see if we can change this or change the software back to the huwaei version (i assume the modem software is custom bt one).
    thanks for any tips/advice
    but i think for other people who want to use powerlines then go ahead!! IT WORKS!

    ok i think i've cracked it
    what i have now done is run 2 powerline adaptors to the homehub as follows:
    one adaptor connected to the ethernet WAN port (the red broadband port) which apparently is ONLY connected to the openreach modem
    another adaptor connected to one of the 3 remaining REGULAR (non WAN) ports which then distributes the network connection as did my previous set up.
    in conclusion, it appears that the WAN port was the source of the problem, not the modem. this red port must be specially configured to only accept communications from the openreach modem and nothing else.
    the only downside is that i have 2 big powerline adaptors connected to the homehub which aesthetically isnt great. and i need to purchase some additional adaptors to re-connect my other 2 devices (given that i've now 'lost' a pair for teh purpose of connecting homehub to modem).
    i think this should be made into a sticky thread as this is groundbreaking information! all the bt people (sales/technical) had no definitive answer for me and the engineer was just as impressed as i was. i am sure this will be valuable information for anyone else who has a setup similar to mine where you need to separate the router from the modem.
    thanks to everyone who contributed to this thread!

  • What is the current vDSL modem hardware revision?

    I know that BT were swapping out some older modems a while back so wanted to know which version of the hardware is latest? If someone could post up a pic of the correct ID label from the base of the modem that would help a lot.
    Cheers

    I mentioned it in THIS POST but unfortunately do not have a picture of the label.
    "The new Modem with a white power plug and lead was unpacked and the version 3b label was shown to me before fitting".
    Btw if your interested there are two versions of  Firmware for the HH3 router.-
    "BT Home Hub 3 – Software version 4.7.5.1.83.8.57.1.3 (Type A) or V100R001C01B031SP09_L_B"

  • TC in Bridge Mode with ISP router vs TC as Ethernet with VDSL modem

    Hi, I have a time capsule. It's the newest generation of the old shape/design - i.e second to newest version. It's running 7.6.4. firmware.
    I recently updgraded my ISP to Fibre VDSL and the ISP sent me a crappy router with a built-in modem that you have to use. I checked the ISP support forums and found plenty of advice to configure the TC over ethernet with this router using the DMZ of the router etc. Anyway, I got it all working but i wasn't happy. port forwarding was a pain and you end up with double NAT issue - not surprising.
    The alternative config was to switch the TC to 'bridge mode' so the crappy ISP router does the NAT / DHCP, port forwarding, dpnp, internet routing. I got this all working and i have made sure that all of my network nodes/clients (wired and wifi) are all off the TC and only use the ISP router for internet, dhcp etc. This is all working with good speeds, solid internet access but...
    Major issues with airplay (use this a lot) and also with stuff like facetime etc. The connection is much faster (40mbps down/10mbps up) than my old ASDL setup but as I said, key services that I use are not as stable.
    I think my only alternative solution is to buy a VDSL modem seperately and use the TC as the router i.e. go back to my old config with TC doing all the routing, port forwarding etc.
    Does anyone here have a view as to whether this is worth trying? I'm hoping that it if the TC is doing all the routing, I will get less drop outs and services will work as they should. On the other hand, I hoped airplay would be OK as it's a wifi/Lan service rather than WAN but I have had quite a few issues.
    Appreciate any help with this and sorry for the lengthy note!
    Jata.

    In theory, you will do better by using a simple bridge mode modem and then setting up the Time Capsule as the router to provide DHCP and NAT services.
    But, as you might imagine, it is not possible to predict whether your results will actually be better using this type of setup.
    Worth a try, in my opinion, if you can find a store that will let you return the modem for credit if it does not do what you want.
    Even a simple modem will still likely have to be configured to operate in bridge mode, but the setup should only take a few minutes using the web based configuration interface.
    Let us know how things are working if you can, if you decide to the try the simple modem approach.

  • VDSL modem/routers and FTTC self-install

    Engineer: Lets have a look at your set up.
    Customer: Well, there is the master socket, well what I think is the master socket (the actual master socket is normally hidden away behind a wall unit) with an FTTC Filter, I then have a double adaptor with a 25 metre untwisted aliminium extension reel I bought from Wilko's. On the end of that is another FTTC Filter with 2 adaptors squeezed into it for my Sky Box, phone and another 10 metre untwisted aliminium extension reel which lead to yet another FTTC Filter with my VDSL Modem on it.
    That's not funny, I've already seen so called engineer installed FTTC connections like that. Hate to think what it's going to be like with self install (Nightmare I think).

  • VDSL Modem

    Hi,
    My VDSL modem as gone ti* up.
    I do not wish to purchased from ebay is there any official outlet where Im able to purchase a BT Openreach VDSL modem?
    if the answer is no, can any inform me how I am then able to use my own router? Im not techincal so require VERY simply replies
    Can you use the HH5 but disable the router element so you are just using the modem for example?
    Thnak to all in advance
    Lee

    As stjp has said, if you want an official white openreach modem, then your only real avenue is to purchase one off of that well-known auction site.
    That having been said, if you do a search for VDSL modem routers, then there are some options from the major manufacturers.
    What I would suggest is to go to one of the specialist suppliers, such as broadband buyer and speak with one of their sales agents, who can suggest an all-in-one unit that meets both your needs and ultimately, your budget.
    I hope this info helps.

  • Alternative VDSL Modem/Router for Infinity

    Hi,
    I'm using BT Infinity and am thinking about replacing the Home Hub and VDSL modem with an alternative. Ideally I want a combined unit so it will probably be a FRITZ!Box Fon WLAN 7390 as there isn't a vast amount of choice at the moment (hurry up Draytek). So I have a couple of questions:
    Has anybody done this? I'm not interested if you've just replaced the router, but has anyone replaced both the modem and the router or just the modem?
    Does anyone know if there's any reason why it would not be possible (does the BT equipment do anything special or identify itself in some way)?
    Does anyone know the correct Modem settings?
    Thanks,
    LJ

    I have just purchased the Fritz!box 7390 VDSL Integrated system to replace the two boxes you get with Infinity. However, irrespective of what configuration I enter into the new router I am unable to actually login.
    It certainly sees BT Infinity and I am getting connectivity at layer 2 and the new Router is showing good upstream and downstream speeds, but I cannot login with either the default credentials or the BT credentials provided to me when I bought the service!
    Anyone know how to get this router or any other router working and with what settings, cause I think I have tried them all..LOL
    Thanks in advance G

  • Time Capsule Airport Connection with Deutsche Telekom 300HS VDSL Modem

    I just swithched my Deutsche Telekom connection to VDSL 50 but can no longer connect to the internet.  There are a couple of configurations I have tried:
    a.    The Speedport 300 HS modem connected directly to the Time Capsule.
    b.    As above, but with the Speedport W700V router in between the modem and Time Capsule.
    The green light on the modem is illuminated to confirm the VDSL is available.
    Could somebody please advise the correct settings in the Airport Utility to make either configuration above work?
    Thanks,

    This is the easiest one.. just use TC in bridge. You go to the airport utility, manual setup, select internet tab and under connection sharing.. off bridge mode.
    a.    The Speedport 300 HS modem connected directly to the Time Capsule.
    This is harder as it depends on the authentication system used by your VDSL..
    The TC has limited options.. either DHCP.. so the vdsl has to pass the public IP as in half bridge type system.. or it has to be PPPoE authentication.. as that is the only other alternative offered.

  • Why can I send email from my iPad, but my iMac which is connected to the same modem keeps telling me that it can't send the message using the same server?

    I have an iPad 2, connecting via Wifi to an Actiontec Q1000 modem.  The iMac (3.06 GHz Intel Core 2 Duo, 4 GB 1067 MHz RAM, running OS 10.8.2) is also hard wired to the same modem.  Internet access is via CenturyLink.  Main email is from Shaw cable in Calgary (Phoenix is a vacation property), not through CenturyLink.
    Can receive email on the iMac, but every time I try to send, I get a pop up saying "Cannot send message using the server .......".  Further prompts me to verify the address in the email, and SMTP settings in Mail preferences, or to select a different outgoing mail server.  I've tried using a number of servers, always the same result.
    Using same settings in both devices.

    Mail is not my forte, but what I noticed was that you have Centurylink and presumably have your Mail set up with their settings? But then you mention Shaw/vacation property/etc - you can send out email only through the server that you have set up as an account using the ISP you are using. If you switch places, do you have separate accounts set up with both Centurylink and Shaw so you can switch and use whichever one you're at? A Phoenix ISP won't work with a Mail POP account unless you're in your home - Phoenix - area.
    Do you have a data plan with your iPad? That would explain why that works - it'll function sort of like a cellphone - works anywhere where there are signals.

  • HT1178 Do I want to create a new wireless network or join my current network?  I can't connect an ethernet cable to the Mac / printer and to the wireless modem at same time - in two different rooms.

    I am trying to set up Time Capsule so that I can do my first backup (after 1 1/2 years!) with Time Machine.  I have read other forums, but in each case they instructions eventually do not apply.
    I have connected my TC to my existing wireless router.  This sits in a bedroom and cannot be moved as a rental home.
    I have plugged in the TC and updated the software.
    Now - do I want to A Create a New Wireless Network (remember I can't connect the TC to Mac using an Ethernet cable). B Replace an existing base station or wireless router with TC (only intend to use for TM as don't know other benefits as of yet). or C want TC to join current network. 
    Thinking C.  If I choose C, it then asks A TC to wireless join current network (NO as already connected using Ethernet). B want to connect TC to my network using Ethernet to extend my existing wireless network. C want to disable the wireless network on this TC and connect it to my computer or network using Ethernet - CANNOT do this as devices can not be in the same room.
    Or do I want to create new wireless network - first set of questions - choice A?  What is the benefit to creating a new one when I won't be in this rental house for longer than 18 more months??
    Please help and quickly!  Thanks!

    Let me suggest some things.
    But first ask exactly what wireless router you have now and what type of broadband service?
    Are you happy with the wireless on the current router? If so, then you can plug the TC straight into whatever computer you have by ethernet, short 1M cord with no connection to the network. And use it without affecting your existing network at all. This is trivial setup.
    Although you don't say exactly what Mac and printer you are using, is it a desktop? Laptop it is definitely easier not to plug it in, but a desktop you can plug in the TC and it will all sit happily together.
    How is the printer connected and to what?
    I am not sure why you need such quick help.. this is all minor setup stuff.. and 18months in todays world is like permanent man.
    Your multiple A, B, C are more confusing than helpful.
    The best choices without more info.. are to replace the existing wireless router with the TC. ie your option B.. but how to do this depends on the type of connection. Is it cable or adsl? Can you easily bridge the existing modem router.. if that is what it is?
    Think carefully in the ideal world what would you like..
    and what do you have..
    We can probably suggest ways and means to fit what you like to what you have.. without introducing a stack of options that are doing your head in.

    I have BT Infinity at home with the BT modem connected to the phone line and then to a BThub which delivers the wif signal. I have purchased an airport extreme to improve wi fi strength if how do I connect up to hub it states connect modem to WAN on back of Airport Extreme.
    Instructions do not mention connection to BT Hub and the BT modem has only one output which you dicsonnect from Hub and connect to airport extreme leaving. Once you do this Hub has no signal.
    How do I rectify
    Paul

    you can also set up the Airport extreme to extend the wireless by hitting the wireless tab in the airport menu then click the drop down menu to select extend
    Apple's "extend" function is a proprietary setting that was designed to only work with other Apple routers.
    It would be extremely unlikely that this setting would work with a BT product, or any other manufacturer's product for that matter.
    But, I haven't tested this with a BT product...and I suppose anything is possible.
    Still, I would be extremely surprised if this worked.
    The AirPort Extreme might "join" the BT network if you try this......but the AirPort does not provide any additional wireless signal coverage when it "joins" a wireless network. In fact, it really does nothing when it "joins" a network except enable the USB port.

    If it is not in Network Adapters and you have no Device Manager errors or disabled devices under Network Adapters then that would be the case.

    Hoping someone can help with setting up my new time capsule.  I am just switching from my extreme to the time capsule.  I can not get the time capsule to go anywhere but to amber blinkiing.  I can go back to the extreme and interenet works fine.
    Here is what I did:
    plugged in the ethernet cable from the cable modem
    plugged in the time capsule power
    Just cycles to amber blinking -- no internet connection
    Tried pulling up the airport utility but it just shows my old extreme configuration and says that it is not supported anymore.  Do not see how to display info on the flashing light.
    I have gone back to the extreme three times and it seems to work fine.
    I also repowered the modem in between trying to get the time capsule to work

    Is this a cable modem? It has to be off for at least 20min and sometimes much longer before it will give up the old settings. You might even need to power down the cable modem overnight.
    Tell us exactly what broadband you have with what ISP and exact model of modem..
    The new TC cannot be setup without using the latest airport utility 6.3.1 or 6.3.2 and you need Lion - Mavericks to use it.
    The computer also needs to have ipv6 setup to local link on whatever you are connecting with, wireless or ethernet.
