DEFINITY ECS Network Connections
are restored and stable, the logic switch is manually reset and the EPN is reconnected to
the links from the switch. There are both command and manual resets. The resets can be
done remotely at the SAT or manually at the equipment.
The SREPN must be administered separately (not as a duplicated PPN) to function in a
disaster recovery scenario. It will not function as a survivable remote EPN without the
administration (stations, trunks, features) to support its operation.

The system can be connected to public and private networks in a variety of ways.

Telephone-Network Central Office, including ISDN-PRI and ISDN-BRI.

■ Auxiliary loudspeaker-paging and music-on-hold equipment
