Abstract: A configuration change management system is provided. The configuration change management system includes a configuration information repository and a human-machine interface for interacting with field-installed communications network entities. Versions of communications network entity specific configuration information are stored in repository entries. Methods of managing configuration changes include: retrieving configuration information from communications network entities; storing thereof under version control in repository entries; comparing at least one retrieved repository entry from the repository; and configuration information retrieved from field-installed communication network entities; and submitting, for reconfiguration, of at least one field installed communication network entity, selected configuration information held in a corresponding repository entry.
