Sending data through the 

BlackBerry Router

 to the 

BlackBerry Infrastructure

You can configure multiple instances of the 

BlackBerry Router

 for high availability. You configure only one port for 

BlackBerry Router

 instances to listen on.

By default, the 

BlackBerry Connectivity Node

 connects to the 

BlackBerry Router

 using port 3102. The 

BlackBerry Router

 supports all outbound traffic from the 

BlackBerry Connectivity Node

 components.
