The system can be programmed to send emergency response notifications (ERN) to one Emergency Response Adviser only.
Multiple emergency calls can result in multiple emergency call notifications being sent to ER Adviser.
After 5 minutes of receiving no acknowledgement from ER Adviser of any ERN SNMP Traps, the retry intervals for multiple emergency call notifications are combined and sent at intervals of 60 seconds until an acknowledgement is received from ER Adviser. At this point, each retry interval is once again determined by the number of retries attempted.
In-progress, unacknowledged emergency call trap notifications are not preserved during a reset.
The system applies digit modification to the dialed digits that are reported to ER Adviser.
While a resilient device is in service on its secondary ICP, emergency response notification is fully supported by the SNMP agent on that ICP, for emergency calls made on that ICP. The secondary ICP must be programmed to sent ERN to ER Adviser. The SNMP Trap does not provide indication that the caller's device is in service on its secondary ICP. Note that on a resilient 3300 ICP, there is no provision for resilient SNMP Trap generation during failover. The SNMP agent that provided SNMP Traps to SNMP Managers also loses service when the ICP loses service.
