Running In ESS Mode

User Enabled telephone features

User enabled telephone features, such as call forwarding and send all calls, will be preserved
when a failover occurred to an ESS server, if the administered features where captured when
translations where saved, and the translations were distributed to the ESS server prior to the
failover.
When an ESS server controls a Port Network, user enabled telephone features will not be
preserved when the system falls back to the Main server. The user enabled feature cannot be
saved to translations on an ESS server and the Main server will have no knowledge of the
settings.

Alarming

The Main server generates alarms when it fails over to an ESS server. The following is a partial
list of the types of alarms the Main server may generate:
Port Network alarms: A major alarm is generated for every Port Network that is no longer
●
under the Main server's control.
Media Gateway: A major alarm is generated for every media gateway no longer under
●
Main server's control.
ATM-EI: A minor alarm is generated for every ATM Expansion Interface board no longer
●
communicating with the Main server.
CSS-EI: A minor alarm is generated for every CSS Expansion Interface board no longer
●
communicating with the Main server.
Platform: If the Main server failed over because of a hardware issue.
●
Until the ESS server controls a Port Network it only produces platform alarms. Once in control
of a Port Network, Communication Manager alarms on the ESS server as it would on the Main
server. An ESS server alarms when it looses communication with an IPSI unless the ESS
server was rejected by the IPSI.
The following is a partial list of the types of alarms generated by the ESS server when it obtains
control of a Port Network:
ESS server alarm: A major alarm is generated when the ESS server controls a Port
●
Network. For more information see,
License-Error: An alarm is generated when the ESS server enters into License-Error
●
mode. An ESS server runs in License-Error mode until it no longer controls a Port Network
or until the 30 day timer expires and it enters into a No-License mode.
No-License: An alarm is generated when the ESS server enters into No-License mode. If
●
the ESS server runs in License-Error mode for 30 days, it enters into a No-License mode.
