NBNCo has a limit of about 1530-some-odd bytes on the VDSL link. It's larger than the standard MTU+PPPoE headers so you can run full 1500, but not enough to run EoMPLS/L2CKTs over it... short by about 6 bytes, so forget about running MPLS-to-the-Edge for layer-2 on FTTN/FTTB stuff. - Ck. >

Hi Shane, We have tested these in our lab - the VDSL performance is acceptable. However there are a couple of downsides... (i) No DSL configuration (ii) No Stats, not even line sync (iii) Price (iv) They use a fair bit of power, and the host mainboard must have a clean well filtered 3.3V
