Blackberry blackberry enterprise server for microsoft exchange manual BlackBerry Router

Feature and Technical OverviewBlackBerry Enterprise Server components and features

Feature	Description
wireless delivery	When you configure an IT policy, all rules take effect when the BlackBerry
	Policy Service delivers the IT policy to a BlackBerry device over the wireless
	network. The BlackBerry device stores new IT policy rule values in the user
	configurations on the BlackBerry device automatically.
	To keep the IT policy rules current, a BlackBerry Enterprise Server sends the
	IT policy to the BlackBerry device over the wireless network periodically.
IT policy coverage	When you add a user account to a BlackBerry Enterprise Server, the
	BlackBerry Policy Service applies the Default IT policy to the user account
	automatically. The user account is not active on the BlackBerry Enterprise
	Server until a BlackBerry device accepts the IT policy.
	You can apply a different IT policy to a user account. If you delete an IT policy
	that you applied to a user account, the BlackBerry Policy Service applies the
	user account to the Default IT policy automatically.
IT policy assignment	You can apply an IT policy to a group or an individual user account.
resend options	If a BlackBerry Enterprise Server cannot send an updated IT policy to a
	BlackBerry device immediately (for example, if a user is outside of a wireless
	coverage area), you can resend the IT policy manually or configure when the
	BlackBerry Policy Service resends the IT policy. The BlackBerry Enterprise
	Server continues to resend the IT policy until it delivers the IT policy.
security enforcement	You can configure IT polices that define security settings for BlackBerry
	devices, the BlackBerry Desktop Software and the BlackBerry Web Desktop
	Manager, and that override security settings that users define on their
	BlackBerry devices. For example, you can configure whether a password is
	required for a BlackBerry device, the length of time that the password can
	exist before it becomes invalid, and the length and composition of the
	password. You can also use IT policies to specify encryption key details.

BlackBerry Router

The BlackBerry Router connects to the wireless network and sends data to and receives data from the BlackBerry Infrastructure on behalf of the BlackBerry Enterprise Server. The BlackBerry Router also sends data to and receives data from BlackBerry devices that are connected to the BlackBerry Device Manager or a Wi-Fi network. The BlackBerry Device Manager is included with the BlackBerry Device Software, BlackBerry Web Desktop Manager, and BlackBerry Administration Service.
