Given the Cartesian coordinate system $(xOy)$, where $O$ is the pole and the non-negative semiaxis of the $x$-axis is the polar axis, a curve $C$ is established with the parametric equations $ \begin{cases} x=2 \sqrt {3}\cos α \\ y=2\sin α \end{cases} (α \text{ is the parameter}) $. Points $A$ and $B$ lie on the curve $C$, with their polar coordinates being $A(ρ_{1}, \frac {π}{6})$ and $B(ρ_{2}, \frac {2π}{3})$, respectively.
(I) Convert the parametric equations of curve $C$ into the standard Cartesian and polar coordinates forms;
(II) Calculate the length of the line segment $AB$.
