(7) When System Initialization or ACDP Initialization are executed at VNDM Center node (the node ac-
commodating the master VNDM data) or the other VNDM Local node in an FCCS network, re-estab-
lishing VNDM data in the FCCS network is automatically carried out to restart ACD FCCS service.
Example: When System initialization is executed at VNDM Center node, re-establishing VNDM data
is automatically carried out as follows (VNDM Center node requests the all VNDM Local
nodes in the FCCS network to send their L-VNDM data to VNDM Center node, in order
of lower FPC number):

VNDM (Variable Network Data Memory)
• VNDM is the data memory concerning Monitor number and OAI Facilities (Subscriber) Information.
• VNDM is controlled by one node (VNDM Center Node) in an FCCS network and transferred to the other
nodes.
If the Program Load or Non Load initialization is executed, this processing will not be carried out. When
Note:
VNDM Local node is re-started up even though VNDM Center node remains in a system down state, VNDM
Local node waits a maximum of 10 minutes for the VNDM Center node's start up. After 10 minutes of the
waiting, VNDM Local node comes on-line as a Standalone ACDP (The system message "26-Y" is issued.).
If VNDM Center node is re-started up after VNDM Local node has been re-started as a Standalone ACDP,
the FCCS link can be automatically re-established (The system message "26-Z" is issued.).
