Hi guys

I have gone through the initiall process of getting VDSL to our office.  Via 3 suppliers of VDSL a preqal said the service would be marginal.  I sort of expected that but that was based on clothed service over existing Telecom line.  The VDSL would be naked over new line.  These are the details:

1) Existing copper pair, currently with ADSL, 1.7km from the roadside Dslam.  Existing ADSL download 13Mbs with Xnet. Torturous route for the cable over neighbours field.

2) Proposed new service - Naked VDSL.  1.3km from roadside Dslam.  Current 16 pair cable under driveway from office to roadside junction upstand. Not connected at this time.  5 less joins in the cable.

So the question is how does Chorus come back with a tested attenuation of (I think it was 15db, it was 2 more than worst allowed anyway) when the cable is not physically connected yet.  Apparently a technician came round and tested it be we have seen no one here and we live on site.

Isn't VDSL chicken or egg.  How do you know the attenuation when the copper pair are not even connected?

Cheers
Andy

If the tests are marginal up to your pedestal on the street then why would a 'new' unused cable from the house to the street help this?
(sorry if Ive misunderstood what you said above).

Sorry if it is confusing.  The existing cable which previous prequal's have been on is 1.7km.  This cable is joined outside our property to a cable that runs down the road, up the neighbours driveway,  across the field and into the house. Total 1.7km from Dslam.

The proposed connection is 1.3km, .4km less.  This includes 70m up the driveway from the office to the roadside join upstand.  5 joins less than the exisiting 1.7km connection and .4km less distance.

The current cable runs to the house with ADSL modem then via LAN to our office which is a separate building near the road.

The proposed cable will terminate in a master socket just for VDSL in the office.

Cheers
Andy

1.3km is still marginal at best for VDSL. The prequal most likely was done to the nearest termination, i.e. where the 'new' cable will start form into your building anyway.

Ok thanks, if that is the case it makes sense.  Is there anyway to find out exactly what Chorus did test??

Simple answer is you're too far to get VDSL2, nothing will change that.

Chorus wouldn't have done any testing unless your ISP requested a manual prequel. The netmap database used for prequel data contains thousands of tests done duing the cabinetisation project which gives a fairly accurate of the attenuation that will be expected at a certain point in the network.

Thanks for clarifying that.  Next question.  Anyway to load share over 2 ADSL lines to increase upload speed?

Talk to your ISP's Business Department.

Yes, ADSL2+ supports port bonding, but as Gooseybhai suggests, you'll need to talk to your ISP. I'm unsure which NZ ISPs support bonding.

If you are with Telecom I can run a detailed line test. But at 1.3km I think it's extremely unlikely.

Thanks for the offer.  1.3km does seem to be marginal at best.  Guess we will have to wait for fibre...could be awhile in Whenuapai.

Ok, Full flavour don't do port bonding. Does anyone know the ISP's in NZ who do?

I am sure SBiddle would hook a brother up with a bonded interface?

Otherwise if there was HSNS or other more expensive broadband connections.
