Paradyne 6212 manual Service Type

Service Type:
cbr (Constant Bit	Supports real-time applications requiring a fixed amount
Rate)	of bandwidth. The applications produce data at regular
	intervals such as a video stream. The user can specify how
	much bandwidth they wish to reserve.
rtvbr (Real Time	Supports time-sensitive applications such as voice. In
Variable Bit Rate)	these applications the rate at which cells arrive are varied.
Nrtvbr (Non-Real	Supports applications that have no constraints on delay
Time Variable Bit	and delay variation, but still have variable-rate and bursty
Rate)	traffic characteristics.
Ubr (Unspecified Bit	Best effort service that does not require tightly constrained
Rate)	delay and delay variation. UBR provides no specific quality
	of service or guaranteed throughput.
