The customer uses the AP Emergency feature to facilitate telephone calls during emergency situations where the central control and/or essential components of the IP infrastructure are not available.

As a rule, this emergency situation occurs only very rarely. For this reason it is particularly crucial that the emergency measures function as intended, should they actually be needed at some point.

It is essential that the function of the AP Emergency configuration be verified by an acceptance test after the initial startup and after substantial modifications.

To this end, each emergency group must be switched over once to the CC-AP/Survivable OpenScape 4000 SoftGate for administration. In emergency operation, it must then be verified that emergency calls, communication to the trunk and other systems in the network, and communication between emergency groups at different CC-APs function as planned. Where applicable, also include installed applications that support emergency operation in the test.

Also verify the communications capability of access points/OpenScape 4000 SoftGates that can be switched to the CC-AP/Survivable OpenScape 4000 SoftGate independently of the emergency group when the group is running in normal operation.

You can conduct the tests when the system load is low.
