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
