I dunno. Back in the 90's I buried a couple of 1" flex conduits from the house to the curb. AT&T gladly pulled a 5-pair cable through it (later abandoning the original 2-pair cable).
When Comcast needed to replace my underground drop, they used the old cable to pull the new cable through the 3/4" flex conduit that the builders buried for them.
We also buried 1" conduit at my mom's place when the drops were relocated and AT&T pulled a 5-pair through that as well.
It really depends on what the AT&T tech wants to do. If they are following the book they will not pull through anything less than 2". As I said I have seen both AT&T and Verizon refuse to use smaller conduits installed by homeowners or GC's.
I have been installing underground for Verizon, AT&T, Comcast and PG&E for almost 30 years so I follow their requirements.
When Comcast trenches and installs their own underground drops they usually install "Cable In Conduit". The conduit is usually 3/4" or 1".
