Messaging Survivability

The IPedge Messaging application can be licensed and configured with a feature called
Direct Cluster Networking (DCN). DCN allows the joining of two or more IPedge sys-
tems (individually referred to as a Node) into a cluster. These clusters act in unison to
maintain the integrity of the messaging database of the entire network. Each node that is
configured into the cluster has a copy of the database of the other participating nodes. If
one node fails, then when IPedge telephones register into another IPedge system, that is a
node participant, all of that user's greetings and messages are available.
Nodes can be geographically distributed in various configurations. Each node contains the
complete database for the entire cluster, and the Messaging application residing on each
node only uses the local copy of the database. Each node is identified by a NODE ID. In
addition all files, including system greetings, user greetings and messages can be repli-
cated to all nodes (standard cluster) or replicated to a designated subset of nodes (hybrid
cluster), depending on cluster size and network capability.

System Fault Finding and Diagnostics

IPedge can detect problems in the system. These conditions can be detected, alerted,
logged, and traced. IPedge includes many useful diagnostic tools.

Alarm Indication of System Faults

Visual Alarms are presented to Enterprise Manager.

Fault Detection and Error Logs

The IPedge system detects and logs abnormalities that it encounters during operation. All
error and trace logs are stored on the hard drive and are monitored by Enterprise Manager.
Examples are trunk failure detection and auto busy-out, IP telephone channel failure
detection and auto busy-out plus error log, etc.

Event and System Administration Logs

Events such as station buttons pushed or lines accessed are stored in an Event Log. All
actions made by the System Administration user are logged. Both logs may be called up at
a later time.

Automatic Fault Recovery

The system can automatically correct certain conditions detected during operation. This
enables the system to continue operating normally without requiring correction.

Backup and Restore

The customer database can be backed up and restored automatically or manually sched-
uled. The customer database can be moved to a network drive or can be moved to another
