Distributed services TOV (D_S_TOV)—The valid range is from 5,000 to 10,000 milliseconds. The
default is 5,000 milliseconds.
Error detect TOV (E_D_TOV)—The valid range is from 1,000 to 10,000 milliseconds. The default
is 2,000 milliseconds. This value is matched with the other end during port initialization.
Resource allocation TOV (R_A_TOV)—The valid range is from 5,000 to 10,000 milliseconds. The
default is 10,000 milliseconds. This value is matched with the other end during port initialization.
