Table 1-1 Interdependencies between VHM and DFM

Component or Feature	Description of Dependency
DFM Installation	A DFM version, which is compatible with VHM, must be installed
	either on the same system as VHM or on a remote system where it is
	network accessible to VHM. See Installing and Setting Up Voice Health
	Monitor on Windows 2000 for server system requirements.
DFM Broker	The DFM Broker maintains a list of active domain managers running on
	the network and registered with the DFM Broker. Domain managers are
	fault management server processes such as VHM and DFM. Each
	domain manager is identified by name and the IP address and port the
	domain manager is running on.
	The VHM installation process can find the DFM Broker if it is installed
	locally. If not, during installation, VHM prompts the user to enter the IP
	address and port for the DFM Broker. VHM then registers the VHM
	domain manager with the DFM broker.
SNMP Trap Receiving	To receive SNMP traps for VoIP devices from DFM, VHM must update
	the trap forwarding filter in DFM. When DFM receives a trap, it
	forwards the trap based on the definition of the trap forwarding filter.
	The VHM trap receiver receives the trap and analyzes it to generate an
	event in VHM.
