Hi,
I'm about to wire up a property for dual/bonded VDSL lines. One will be naked and the other clothed. I plan to install a master filter on the clothed line at the ETP.

I picked the location especially because it's close to the exchange so want to make sure that I do everything possible to maximise the line speeds.

Bearing in mind the line length from exchange is around 100 metres (Prequal came back with 1dB attenuation), I have two questions:

1. Will running two VDSL services down the same ~7m of Cat6 cable be a problem (ie: Should I run two Cat 6 cables from the ETP to my two modems)?

2. The lead in from the plastic pillar is ~18m of 4 core (2 pair) non twisted pair in a conduit. Chorus can replace it with 23AWG twisted pair cable for a small fee (around $200) - is this worthwhile?

edit: Changed "will replace" to "can replace"

Hello... Our robot found some keywords in your post, so here is an automated reply with some important things to note regarding broadband speeds.

If you are posting regarding DSL speeds please check that

- you have reset your modem and router

- your PC (or other PCs in your LAN) is not downloading large files when you are testing

- you are not being throttled by your ISP due to going over the monthly cap

- your tests are always done on an ethernet connection to the router - do not use wireless for testing

- you read this topic and follow the instructions there.

Make sure you provide information for other users to help you. If you have not already done it, please EDIT your post and add this now:

- Your ISP and plan

- Type of connection (ADSL, ADSL2, VDSL)

- Your modem DSL stats (do not worry about posting Speedtest, we need sync rate, attenuation and noise margin)

- Your general location (or street)

- If you are rural or urban

- If you know your connection is to an exchange, cabinet or conklin

- If your connection is to a ULL or wholesale service

- If you have done an isolation test as per the link above

Most of the problems with speed are likely to be related to internal wiring issues. Read this discussion to find out more about this. Your ISP is not intentionally slowing you down today (unless you are on a managed plan). Also if this is the school holidays it's likely you will notice slower than usual speed due to more users online.

A master splitter is required for VDSL2 and in most cases will improve speeds on DSL connections. Regular disconnections can be a monitored alarm or a set top box trying to connect. If there's an alarm connected to your line even if you don't have an alarm contract it may still try to connect so it's worth checking.

I recommend you read these two blog posts:

- Is your premises phone wiring impacting your broadband performance? (very technical)

- Are you receiving a substandard ULL ADSL2+ connection from your ISP?

1. running both down the same CAT6 cable will be fine
2. For $200, I'd replace it, but I'm sure most of those 2pair lead'ins are twisted (even lightly twisted) and should be ok. It was the old single pair ribbon type that is bad for VDSL.
