That does sound as though one of those cabinets is an FTTP one.
Openreach FTTC, (BT Broadband Infinity is just one ISP's offering) handles connection speeds slightly different from what you are used to.
You can expect an IP Profiles of 38717kbps down, 10000kbps up. (Upload sync will show as 10000kbps on the engineer's test as well). Maximum download speed in reality depends on your ISP just like it does on ADSLx, but plenty of people get 36Mbps or more.
I'm about 600 metres from my cabinet and connect at 39992/10000kbps. Actual speeds vary around 35Mbps/8Mbps.
