System Shutdown

What Happens When I Give the System Shutdown Order?

• The system asks for permission to shut down the node (module).

• The node's phone lines are displayed with their state indicated ("active", "idle", or "stopped")

• Phone lines that are carrying calls at the time you give the shutdown command are taken offhook when the caller who leaves a message, or the user who is logged into a mailbox, either presses a key or allows a silence timeout.

  • The caller or user hears the shutdown warning and is disconnected:

    "I'm sorry, the system is currently shut down for maintenance. Please call back later."

    EXAMPLE:If the shutdown occurs while a user is making a message for another system user, he can continue to record the message. But when he presses a key to review the message, or stops recording for the silence timeout interval, the system interrupts the call, plays the shutdown warning, sends the message, and logs out the user.

    - Phone lines taken offhook by the system are listed as idle in the line states display (prevented from answering new incoming or outgoing calls).

    - Phone lines with interrupted calls are listed as stopped in the line states display.

• All message-waiting indicator requests are canceled. Message lights are turned off even when there are unplayed messages in mailboxes.

  • Pager/message delivery calls and re-pages are not made during shutdown or afterward.

  • Message Indicator Request Queue Length shows how many message requests were lost on shutdown.

  • The system displays the status of each line and the lengths of the message indictor and paging request queues.

  • Lights are not turned on until new messages are received after shutdown.

• Callers who try to access the shutdown lines will hear a busy signal until the system is completely rebooted.
