Messaging Survivability; System Fault Finding And Diagnostics; Alarm Indication Of System Faults; Fault Detection And Error Logs - Toshiba IP edge General Description Manual

Both VoIP Option/SoftIPT and IPT relies on its connections to the Call Processing module
to determine whether or not to switch over, and Call Manager relies on the connection to
Net Server to determine whether or not to switch over.
If a component failure such as Net Server module or Call Processing module shutdown
Note
takes place instead of the complete server failure, Call Manager and the phone may connect
to different IPedge systems. In that case, the user can manually override the survivability to
reconnect to the same IPedge system.
Call Manager survivability is supported for the IPedge built-in Net Server. ACD or Unifier
based Net Server is not supported.

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. Note that all of the nodes in a
cluster must be running the same version of the IPedge system software.

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.
