Dynamic System Resilience

A feature that supports a primary zone core and backup zone core established at two geographically separate master site locations to protect against a catastrophic failure of zone core equipment at a single location. The backup core provides the same level of redundancy as the primary core. If either zone core were to fail, the other zone core would take over. The DSR feature provides redundancy for voice, transport, and other subsystems by establishing two zone cores for a given zone at two geographically separate master site locations.
