I'm a system administrator for a large seasonal resort. There are approximately 150 summer cottages there. All are currently served by a mix of ADSL and VDSL2 over twisted pair telcom feeder cables.
The longest runs are 3000 Ft or 914 meters.
The twisted pair cabling looks like this:
As you can see there is no "binder" or plastic coating separating pairs. They are just all mixed together.
We are considering replacing all the ADSL2 equipment with VDSL2 DSLAMs.
I'm very concerned that this could lead to major performance issues due to increased crosstalk between pairs. I know ADSL2 handles this better.
Is there any way I could better account for this risk? I don't want to buy $30,000 worth DSLAMs plus the labor cost of installation only to have the deployment fail.
