I'm designing a setup for which a 60GHz radio link will be installed between two buildings.
One building host ISP lines while the "remote" has no ISP line at all.
Building are 60m from each other and I expect a 300Mb/s throughput through this 60GHz radio (Wireless Wire Dish).
There is a private telephony line between these buildings.
With a pair of CO/CPE VDSL devices, I can hope for a 80Mb/s throughput.
What do you recommend for this ?
1. Using DSL line as a backup with automatic fail over
2. Using DSL line as a backup with manual fail over
3. Grouping both lines together ? How exactly
4. Not using DSL line at all as 60GHz radio outperforms DSL
