Like many folk round here we've just been upgraded to VDSL, but my max speed is about 7mb per second @ 900m from the box. Now the attenuation is pretty high, about 33db so figured fit Dynamix VDSL splitter/filter.  

 

I figured connection pretty easy -only 6 wires, but cant get it to work.  Currently the feed from the street is the Blue and White pair. When this is connected up to the RJ45 socket to the Bl/Wh we get speed varying from 1mb to 8mb.  So logically I match these up with the Bl Wh pair on the filter, which means the Green White pair are the new DSL or Modem line - now here is the problem - the wall jack is the RJ45 type (will work when Blue pair connected to the Blue/White on the wall plate) but when I connect the Green Pair to No 1 and No 2 (Wh/Gr and Gr/Wh respectively) on the jack, no VDSL.  Modem is fritzbox 7390, using Cat5e cable connector.  Do I have a faulty filter ?  Answers on a postcard please !

 

Not utilising a phone line, so orange pair redundant

Output of the splitter has to connect to the blue pair on the outlet. If you do not have a phone or anything then do not expect any changes tho, its only when you are using the splitter to get phone wiring off the DSL connection that it will actually help.

Thanks for the quick reply Rich.  Have tried connecting the green pair to the blue jack points as I figured the filter just attempts to clean the signal a bit, but no internet that my Fritzbox can detect,

At 33dB attenuation you shouldn't have got VDSL. That line must be a lot longer than 900m. May be better off with ADSL as it will probably be more reliable

With stats like that you will get better performance on ADSL2+ than VDSL2. You're probably not as close to the ISAM as you think you are.

It's not clear if the splitter is being installed at the ETP or first jack point which is where splitters really have benefit.

 

However, I just wanted to point out that @richms statement is only partially correct in this case - as the line is so long, its unlikely to get much use of the higher VDSL spectrum so any wiring stubs are probably not going to affect the service tooooo much. 
In saying that, it's impossible to tell from the OP if the low sync rate is due to home wiring issues or not. 


In 90% (that's a made up statistic) of VDSL services, a central splitter will make an improvement regardless of if it is a naked service or not. you need to eliminate home wiring intricacies and issues, by using splitters, to get the best VDSL performance regardless of POTS phones being present, or not.

Edit: fixed an ambiguity

Nice to see you about again Brent :)

 

 

 

Sounds like your line is simply too long, but as you have a fritzbox, Please post the spectrum screenshots. This will provide a bit more of an indication into the specifics of your connection.

Sounds like you haven't connected up filter correctly - orange pair should not be redundant

Your right, i totally missed that in the previous posts... training has me drained haha..

 

 

 

 

 

@OP on your filter it should say "Or/wh to LINE and Gr/wh to MODEM Bl/wh to PHONE wiring"

 

 

 

what this translates to is Orange connects to the 049 Service lead

 

Blue connects to Phones

 

Green connects to DSL.

 

 

 

For a RJ45 jackpoint, you want to use the Two center pins (4&5 or Blues)

 

Double check those colors

OK folks here is the stats page from Fritz, attenuation seems to have improved and so has  DSL as the connection has been live longer, though neighbours probably not online !

Perhaps the fritzbox is set up wrong , though I've setd it up to voyager specs-  according to spark vdsl is available

just because its avaliable doesnt mean you can get it unless you sign up for it. its a different service and requires your ISP and Chorus to configure their systems to connect you up.

Can tell you right now, Your line is not running on VDSL at all.

 

 

 

If you have requested VDSL to be provisioned it

 

a, Has not been done yet.

 

b, Has been a failed install for your line being too long - A notification to you should have happened in this case.

 

 

 

VDSL Does not fall back to ADSL.

If a prequal says yes, An ISP will put the request through.

 

 

 

Chorus can then choose to deny it.
