Activating an LTU involves removing the state "manual blocking". When an LTU is activated, all hierarchically subordinate units are also unblocked by the CDC (Device Configuration, a part of Dependability).
The system units are activated without testing.
Before it is activated, the state of the LTU is interrogated. If the LTU is in a state that does not permit activation, the "activate" order is not issued, error message F22 is issued to the operator and the AMO is terminated.
After the "activate" order has been executed, a message is output providing information about the new switching state. No test is made after an LTU has been activated.
If an LTU is not specified, the LTG is activated.
Before activating the LTG, the AMO checks that it is configured. If it is configured, then the presence of the LTG is reported to the operating system. Activating the LTG may take up to several minutes. Thus, the AMO does not wait until the activation job is completed, but terminates immediately issuing advisory message H13. The present loadingstate of the LTG is displayed on DB-board.
When activating an central SIU, the AMO first sends a deactivation command which is immediately followed by the activation command. This ensures that the current circuit data is reloaded. In the case of a duplex LTG, both central SIUs of the LTG are reloaded. In such cases, the operator receives two advisories. Peripheral SIUs has to be switched by means of AMO BSSU.
WARNING: If an central SIU is activated on a running switch, DTMF tones will be lost during the deactivation and loading processes. Therefore, it is recommended that central SIU re-activation be done during low traffic periods to avoid any service interruption.
Activating an HDLC-DCL highway may take up to several minutes. Thus, the AMO does not wait until the activation job is completed, but terminates immediately issuing the advisory message H25.
Activation of RTM board has two types : BOARD and DATA. BOARD type activation is handled same as the SIU activation. The error and advisory messages ; F24, F25, F26 , H19 and H28 are used both for SIU and RTM activation.
For AP shelves (LTU from 17 to 99), there is a new mechanism. The AP shelf can not be activated before the connection to the AP shelf is established via EXEC-USSU.
