Abstract

PURPOSE:To surely diagnose a diagnostic object device to the utmost with respect to the network diagnostic system in an ATM exchange provided with a network device of duplicate configuration. CONSTITUTION:When a standby system diagnostic path 3001 for executing diagnosis from a central controller 2001 can not set to a standby system configuration device 1011 constituting a standby system network equipment 1001, the system takes duplicate configuration with the standby system configuration equipment 1011 being a diagnosis object. An active system diagnostic path 3000 is set to an active system configuration device 1010 forming an active system network equipment 1000. Then the diagnosis of the standby system configuration device 1011 being a diagnosis object is executed via the active system diagnostic path 3000 and the active system configuration device 1010.
