Broadband and virtual Landline

[#1]

I've currently got a 4 months left on my broadband contract and I'm looking at what to do with our landline.

I've seen a number of services available that provides a reasonable service.

My question is can I transfer my current landline number to a virtual solution and still keep my broadband service?

[#2]

The only way to do that, if you wish to stay with PN, is to ask for your BB service to be switched to SoGEA, and once that is done, move your phone number to a VoIP provider, within 30 days.

And then hack the hardware?

[#4]

@mechanic123 Why would you need to do that?

[#5]

Why? To replace the function that the filter seperating the data stream from the phone line currently supplies?

[#6]

If you are on SoGEA with a VoIP service, the 'phone'  side is over the internet, and doesn't need separating.

@mechanic123 assuming we are talking about the DSL filter, then it doesnt separate the data stream, it just prevents interference of the high frequency DSL signal by the low frequency phone signals.

As @jab1 says, when there is no analogue phone service there is no interference to prevent , hence no filter required!

So where would I plug the RJ11 connector in?

[#10]

@mechanic123  The same place it is plugged into now. The DSL connection is a direct connection to the line. It is only the POTS phone connection that is filtered. So just use the existing  data connection on a filtered faceplate or separate filter.

That would put wideband data onto the phone leads - not good surely? Isn't that what the adsl filters are supposed to filter out?

[#13]

Perhaps a picture will help ?

Here is a very simplified circuit diagram of a DSL filter.

As you can see, the 'modem' outlet is wired directly across the incoming landline - and is NOT filtered !

The 'phone' outlet has an inline filter that passes through low frequency voice signals but blocks frequencies above 3KHz coming FROM the telephone handset and internal phone wiring, which otherwise could interfere with high frequency DSL signals and reduce broadband performance.

Once a line is converted to SoGEA and the analogue phone will never be used again, if you still wanted to "hack" your hardware, you could try and return to the simplest setup, by replacing the landline Master Socket filtered faceplate with the original unfiltered phone socket faceplate,  and then get yourself a replacement DSL cable with RJ11 to BT431A plug, which you would then connect into the unfiltered phone outlet.  Theoretically not having a filter on the line, should slightly reduce the insertion loss of your Master Socket and might slightly increase the available VDSL signal, and consequently there is a small chance that sync speeds improve.  I suppose if you really wanted to go hardcore minimalist, you could plug the RJ11/BT431A DSL cable in to the landline "TEST socket" and eliminate the faceplate entirely !

@mechanic123  You say .. " That would put wideband data onto the phone leads "  I don't quite follow, there is no phone service so no phone connected to the incoming copper line if you switch to SOGEA.

Perhaps you are thinking of VRI (Voice re-injection) where internal phone extensions could be connected to a VOIP service from an ATA or router to allow standard phones to be connected around the house? The extensions would be disconnected from the POTS line so would have no DSL data on them so no filtering required.

So what's the relation of voip to sogea? If we have to use voip, how is that saving me money? And do I need a new phone?
