Hey guys,
A couple of question on Chorus' termination.

Firstly is around the termination on those in premises locked boxes. These are around 15x15cm, have a lock on them with around 5 numbers/letters. The black cable comes in from the road and is punched into a punch down block on these. If we get a new connection, how do we know which punch down block it applies to? Or are we best to get one of these signal tester devices which light up when they detect current on the cable?

Reason I ask is that a VDSL connection only is $99 and a connection and wiring is $399 for basically a Chorus tech coming and telling us which pair it is.

Secondly my GF's place has terrible speeds. She's synced at like 2000kbps/800kbps in an inner city (non cabinetised) Auckland suburb. The ETP is quite far from the house so can I hook the modem (12v) up to a 12v car battery so I can test sync speed from there?

Call Telecom or the ISP and ask which pair the VDSL is on at the termination point.

If your router has a 12V input then just be careful about the + and -... Can you get stats from the modem in the house? Attenuation and SNR are useful to know.

Time to find a new industry!

Oh Cool, if the ISP knows then that's all good! Yup will try to get stats on Monday. Thanks for the help!

they don't know unless they go and ask chorus.

I'm pretty sure filter install is $250 not $400.

when the new connection is installed and tested they should leave it labeled for you to pick up, although it might be labeled with what is called a ASID number, which really means nothing to the customer, from memory ASID numbers start with 162

Anything I suggest or say is my own thoughts and not provided by anyone else unless stated

why dont you just get a cheap multimeter, stick it on DC volts and put it across a pair to see a voltage close to 50? That'd tell you a line that has been connected, although it would also show voltage if the lines are terminated by chorus but not active. Trial and error would seem to be the way to go assuming you wouldnt interrupt anybody else's services connected there.

It's not uncommon on the average building MDF to find that the vast majority of pairs will quite often be jumpered to the NEAX MDF in the exchange and will have a disconnected tone. If somebody moves our disconnects a line it's typically left jumpered at the exchange so the same pair can be easily reactivated in future.

Hey guys,
