Remote Maintenance
This feature allows station and trunk changes or reassignments to be performed without a site
visit by service personnel, and can be used to retrieve fault codes prior to visiting a site. One
Remote Maintenance center can service an unlimited amount of systems, thus reducing the
amount of personnel to maintain each site, travel costs and customer billing for each site.
