150 Mbps, you're lucky. Here AT&T has to bond 2 pairs so I can get 25
Mbps. At least it's not comcast. I wonder how many pairs they could
bond. Is there a technical limit or is it just a matter of how many
they want to bond? As more people abandon landlines, that leaves more
capacity for AT&T to bond multiple pairs for internet customers.
