Bandwidth engineering considerations
The bandwidth available for communication between the main DEFINITY ECS host and
the Avaya R300 is dependent on several factors. The following gives a high level
overview of the items for consideration. The Remote Office has three principle forms of
traffic back to the host site (See Figure 9):
■ Voice bearer traffic (carried on IP streams, over WAN network channels)
■ H.323V2 call signaling/registration traffic (carried on IP streams, over WAN
network channels) and tunneled maintenance
■ IP routed data network traffic (carried on PPP streams, over WAN network
channels)
