11.2.12.2. Administrator Switchover of Access Points/OpenScape 4000 SoftGates via AMO

Administrative switchover of access points/OpenScape 4000 SoftGates to and from the central control to CC-AP/Survivable OpenScape 4000 SoftGate is possible at any time.

The task is forwarded to the OpenScape 4000 host system via AMO. From there, it is sent to the affected CC-AP/Survivable OpenScape 4000 SoftGate via an affected access point/OpenScape 4000 SoftGate. Finally, the CC-AP/Survivable OpenScape 4000 SoftGate instructs the HG 3575 of the affected access points/OpenScape 4000 SoftGates to start up with the requested control (central control (host) or CC-AP/Survivable OpenScape 4000 SoftGate). If more than one CC-AP/Survivable OpenScape 4000 SoftGate is affected, this process is repeated for each CC-AP/Survivable OpenScape 4000 SoftGate.

Communication from the OpenScape 4000 host system to the CC-AP/Survivable OpenScape 4000 SoftGate via access points/OpenScape 4000 SoftGates requires that at least one access point/OpenScape 4000 SoftGate has a connection to both the central control and the CC-AP/Survivable OpenScape 4000 SoftGate. If this is not the case, switchover cannot be initiated.

The switchover can take place at various levels:

all access points/OpenScape 4000 SoftGates of all emergency groups of all CC-APs in the system
EXEC-APESU:SYSMODE=EMERG,LEVEL=SYSTEM; switches to the CC-AP/Survivable OpenScape 4000 SoftGate EXEC-APESU:SYSMODE=NORMAL,LEVEL=SYSTEM; switches to the central control
all access points/OpenScape 4000 SoftGates of all emergency groups of one CC-AP/Survivable OpenScape 4000 SoftGate
EXEC-APESU:SYSMODE=EMERG,LEVEL=CCAP,NO=99; switches to the CC-AP/Survivable OpenScape 4000 SoftGate EXEC-APESU:SYSMODE=NORMAL,LEVEL=CCAP,NO=99; switches to the central control
all access points/OpenScape 4000 SoftGates of one emergency group (of one CC-AP/Survivable OpenScape 4000 SoftGate)
EXEC-APESU:SYSMODE=EMERG,LEVEL=APEGRP,NO=2; switches to the CC-AP/Survivable OpenScape 4000 SoftGate EXEC-APESU:SYSMODE=NORMAL,LEVEL=APEGRP,NO=2; switches to the central control
one access point/OpenScape 4000 SoftGate (of one emergency group (of one CC-AP/Survivable OpenScape 4000 SoftGate))

EXEC-APESU:SYSMODE=EMERG,LEVEL=AP,NO=99; switches to CC-AP/Survivable OpenScape 4000 SoftGate EXEC-APESU:SYSMODE=NORMAL,LEVEL=AP,NO=99; switches to the central control

IMPORTANT:

The switchover is always performed for all selected access points/OpenScape 4000 SoftGates that have contact with the requested control, regardless of group rules. If some access points/OpenScape 4000 SoftGates in a selection (SYSTEM, CC-AP/Survivable OpenScape 4000 SoftGate, APEGRP) do not have contact with the requested control, these are not switched over. The AMO then issues the message “partially performed“. Following a partial switchover, resources important for operation (such as trunk lines) may not be available for a group! For this reason, the connection status must be queried and verified before a manual switchover. See Section 2.11, “Querying the Connection Data”.

IMPORTANT:

Access points/OpenScape 4000 SoftGates that are switched over independently of the group and that do not have their own trunk or tie line only allow access point/OpenScape 4000 SoftGate internal communication. This prevents emergency calls from being forwarded over the trunk, for example.
