A METHOD OF MANAGING DIGITAL SIGNAL CARRYING FACILITIES

摘要

A method for managing transmission lines within a communication system which enables the automatic restoration of network access for user lines. The communication system includes user lines interfaced with groups of transmission lines and each group of transmission lines includes dedicated transmission lines which are connected to the user lines, idle transmission lines and reserved transmission lines. The method makes a number of idle transmission lines among the groups of transmission lines available for coupling by user lines which have a dedicated transmission line in a group of transmission lines that fails. The method determines the minimum number of transmission lines to be reserved by a comparison of the numbers of certain types of transmission lines in the different groups.
