I was curious about the 10 year old ADSL splitter I had.

I am at about 0.7km from an exchange and Synch up at about 14Mbps on ADSL2+.

I decided to disconnect my splitter and hence all phones downstream.
This left only my Dynalink RTA1320 connected on the incoming line.

The Synch remained at 14Mbps.

Cheers

My first ever AM radio network connection was with a 1MHz AM crystal(OA91) radio receiver.

Removing the splitter won't make any difference to your speed.

You won't however be able to make a phone call and use the internet at the same time however as there is nothing to filter the data and voice - this is why a filter is for.

Tells me your 10yr old filter is doing just fine.

I don't know much about my 10 year old splitter or what the difference in input impedance on the line side at 1 or 2MHz for ADSL or ADSL2+ splitters.

So I figured that if I removed the splitter I might see some Synch difference if the splitter had limiting or loading characteristics at the upper frequencies.

Why are there ADSL2+ splitters on the market?

I assume you had a wired in filter ie MM3200B which has been around for 10yrs, although some earlier ones had slightly more compact housing, but were of similar spec. Essentially they are well rated beyond the requirement of ADSL2+ (ie 2.2MHz) but not upto 17MHz as needed by VDSL2.

So end result is even though it predates ADSL2+ the same filter is now spec'd for ADSL2+ quite simply because it can.

Thanks Cyril.

Can't see any ID on the wired in filter. The filter came with the house.

I guess 14Mbps is about right for 0.7km.

When VDSL2 turns up it I will require a new filter and router.
