A device for enabling automatic restoration of network access for user lines within a communication system. The user lines interface with groups of transmission lines that include dedicated transmission lines which are connected to the user lines, idle transmission lines and reserved transmission lines. The device includes a line manager that makes a number of transmission lines among the groups of transmission lines available for user lines which have a dedicated transmission line in a group of transmission lines that fails and a reprovisioning element that couples each of such user lines to a respective available transmission line. The device may also include a monitor that delays the coupling of such user lines if a sufficient number of transmission lines are not available.
