Wrong service wiring.
« on: May 13, 2015, 08:09:32 PM »
Hi All.    First ever post !
One month into VDSL.
My GPO installed all underground service, arrives within 300mm of the NTE5.
I have the orange & white pair connected to blue/white & white/blue  & then to 2 & 5 in the NTE5.
The order is orange to blue/white to 2.
All perfectly standard.

My highest tone is 3598.  I could have tones to 3959.  Huawei cab 625m away.
I did a check,  The ORANGE (B wire) should be at -50V to earth.

But in my pair the WHITE (A wire) is at -50V, & that is the wire to 5 on the NTE5.

The question is ( at last )  DOES IT MATTER to VDSL ??

Hello Malcolm, welcome to the Kitz forum.

The reversed polarity on the pair is not a problem for any xDSL service nor is it a problem for the telephony service.  :)

Hello,

I wonder if anyone can tell me if reverse polarity on the pair would be a problem for any xDSL service or a telephony service?

I've searched *everywhere* but can't find an answer.

Under normal circumstances it should never be necessary to reverse the polarity, however in an emergency or at a location with high levels of tachyon/neutron flux it can be required. it is perfectly safe so long as the streams remain uncrossed.

Where can I get this new Krone punchdown tool that's claimed to help with reverse polarity neutron flow on my incoming wire?  I still don't know if it's affecting my xDSL service and/or telephony, but want to rule it out.  Thanks.

According to Wikipedia - https://en.wikipedia.org/wiki/British_telephone_sockets

The two wires from the exchange are denoted the B leg at -48 V relative to ground when the line is not in use and the A leg which is near ground potential when the line is not in use. The A leg goes to pin 5 and the B leg to pin 2 in the master socket.

I think A was called tip and B was called ring - https://en.wikipedia.org/wiki/Tip_and_ring
