A phone number is structured as $\text{LMN-OPQ-RSTU}$ where each letter stands for a distinct digit. The digits within each segment are arranged in increasing order: $L < M < N$, $O < P < Q$, $R < S < T < U$. The middle segment $OPQ$ consists of consecutive odd digits; $RSTU$ comprises consecutive even digits; and $L + M + N = 10$. Determine the greatest possible value of $L$.
