Reliability and Recoverability
The system is designed to recover from a power outage or other failure instantly, regardless of the source of the failure. Each port network includes a set of segmented, parallel buses. If one of the paired segments fails, the other bus segment continues to handle communications. You can always further enhance the system’s reliability by duplicating critical components such as processors or
Configuring for Reliability/Recoverability
DEFINITY ECS can be configured to meet the disaster recovery needs of any business. For example:
■Calls can be routed through an alternate DEFINITY ECS if one site is destroyed or disabled by natural or
■Multimedia (voice, video, data) connections to the network can all be made redundant, in case of network failures. The system can be routed through multiple public exchanges to protect against network failures (a cable or fiber being cut, for example).
■DEFINITY's universal hardware and flexible software allow systems to be re configured quickly in emergency situations. Port networks can be added and network routing can be changed in a matter of minutes.
■The TN2211 Optical Drive will replace the present TN1656 Tape Drive. The new Optical Drive will provide the same functionality as the Tape drive, such as, storage for software upgrades, translation backups, announcement file backups, core dumps, etc. It is also faster than the Tape Drive. A full backup to the Optical Drive will take approximately 20 minutes. The present Tape Drive backup takes about 95 minutes.
