exactly - it could be shipped with the router and a "how to" picture guide... BUT, theres always those that dont have an NTE-5 such as new builds (XNTE) and old builds (LJU) and therefore a technician must install an NTE5 + SSFP on the circuit near the entry point of the drop wire (or cable coming in from the XNTE) ...
I think it will be a failed trial - too many people with bad internal wiring and/or using the router on the 5th extension box upstairs and/or with other extension sockets unfiltered with devices on such as phones and sky multi-room boxes - this will raise customer 'churn' when end users are getting sub optimal FTTC speeds - Ideally self install filters should only be sent out to those that have only 1 master socket and thats it! ...bridged taps anyone??
Bridge (Bridged) Tap
A bridge tap is an unterminated branch in a cable, or any branch on a pair that is not a direct connection between the Line and the subscriber.
Any signal transmitted on the main copper pair will also travel down the bridge tap. Open end of the bridge tap (or high impedance when
filter is installed) will result of the signal being reflected back towards the main copper pair. In the voice band this reflection will result in echo;
in the DSL band it will lower attainable data rates.
In the case of longer bridge taps (20- 40 ft) very drastic changes in data rates will occur due to significant changes in insertion loss and impedance.
in laymans terms (for those unaware) - having your filter and modem on first socket in your home but the signal travels down to all other 'extension' sockets and reflects back into the modem, this can degrade VDSL signal drastically - ADSL signal not as much but can impact it, this is why its best terminating the xDSL signal at the master socket with an SSFP rather than a dongle filter (which does not terminate it at master socket)
VDSL2 + SELF INSTALL DONGLE FILTERS = BAD IDEA!!!
Don't agree Snadge. Pretty much most of your arguments could also be applied to ADSL, which, if I remember correctly was offered as self install or engineer install if you didn't feel up to it !! It might even have been engineer only originally (it's been a long time and BE's memory isn't what it used to be !!).
Anyways, I think self-install is a good idea. There was absolutely no reason that I needed an engineer to get VDSL2 going, other than putting some more money into BTOR's pocket.
Being brutally honest, only the more tech savvy and 'clued up' customers would know if they were receiving sub-optimal speeds and these are the same people that will already know how to optimise their connections. The rest of 'joe public' will just know its faster than their old conection and most likely, be happy with that. If you don't agree, look at your neighbour whose connection you 'broke'. Perfectly happy until you brought to his attention that it should be a lot better. Most users on VDSL2 will be exactly the same. What you don't know....etc etc
fair enough, all im saying is VDSL2 is
highly affected by bridged taps and poor wiring (more so than ADSL) and (I think) thats why it required a visit in first place.. otherwise they would have just sent dongly filters out from day 1, also when people are upgrading to fibre they do so to get 'faster speeds' so the first thing they are likely to do is 'check' it on speedtest.net , there are many 'inbetween' users (more than tech savvy) who dont know how to make sure its optimal or how it works BUT knows how to use a webiste to check to see if they are getting 40Mbps or 80Mbps...and when they are not, customer churn will increase when they start calling their ISPs to tell them they are getting 15Mbps and its all down to internal wiring/conditions and setup - ADSL1/2/2+ while also affected by same conditions is not as sesitive as VDSL2 and seeing as VDSL2 is sold as a superfast fibre broadband package then its best to make sure its exactly that, BT know that internal wiring can severely degrade a VDSL2 signal, whereas with ADSL it can have some impact but not as much as it can with VDSL2
I suppose what I mean is its a bad idea for ISPs if they want to keep churn down, maybe if they send out a booklet or paper with the dongle explaining how wiring setups can affect speeds, so if the user does get less speeds he can determine if his internal wiring MAY be a cause because he/she has been pre-educated.
