	Parameter	Description
	Service type	It specifies the traffic management type used for the PVC.
		z UBR Without PCR: The ATM network makes the best efforts
		to transmit UBR user information. This is called best-effort
		transmission. The transmission quality, such as cell loss,
		transmission delay, and jitter, cannot be guaranteed. This type of
		service is applicable when an end-to-end error tolerance
		mechanism or protocol is designed in the higher layer and the
		applications do not impose stringent requirements on network
		transmission capability.
		z CBR: A fixed bandwidth (or rate) is required. This type of
		service is applicable to real-time audio and video signal
		transmission.
		z Realtime VBR: Stringent requirements are imposed on
		transmission delay. This type of service is mainly used for
		services with stringent requirements on real-time performance,
		such as video monitoring and compressed voice
		communications.
		z Non Realtime VBR: This type of service does not impose
		stringent requirements on transmission delay. For example, a
		transmission delay of multiple seconds does not affect the image
		quality when a user retrieves the image coded with MPEG-2
		from the video server through the ATM network. The
		transmission rate between the user and the network, such as the
		PCR and the SCR, however, needs to be specified to reduce the
		cell loss probability.
