35b promises to deliver speeds over existing VDSL2 up to 300 Mbit/s D/S and 100 Mbit/s U/S on loops shorter than 250m.
On longer loops, 35b falls back to VDSL2 17a vectoring performance. 35b uses the same tone spacing as VDSL2 17a to allow vectoring across 35b and 17a lines, and thus mixed deployments and a smooth introduction of 35b.
