The BGW has two Ethernet ports - INT and EXT.
 The INT port is connected to the internal network in the headend’s Master Unit to provide the local
network for all the modules and the Remote Units. It also provides, via the built-in switch in the Master
Unit, a way of locally configuring the network. It provides the web interface for all the settings of the
system as well as many other functions.
 The EXT port is a “northbound” Ethernet port that allows the BGW to connect to the Internet, or a WAN/
MAN type of larger network. This means that the system can be monitored and managed remotely.
The BGW is the unit responsible for alarm handling and remote forward of alarms either by SMTP mail forwarding
or by SNMP traps. A MIB file for your SNMP system is available from Bird upon request as well as documentation
regarding SNMP.
If the BGW is replaced the Remote Units may not show up immediately. This is due to the lease time on the address
they have. Eventually they will request a new address and when this is done they will show up.
The BGW can also launch VPN tunnels to a remote supervision center, the CGW. The CGW makes it possible to
manage multiple systems from a single location.The CGW can handle a large number of such tunnels, providing a
central point for supervising all the installations and collecting alarms and statistics from all the systems as well as
centralized alarm management. The BGW can support a second VPN tunnel to the Bird management center
providing supervision and management assistance, if needed.
