USRobotics U.S. Robotics SureConnect ADSL Ethernet/USB Router manual Service Name Description

U.S. Robotics SureConnect ADSL Ethernet/USB Router User Guide

The following table briefly describes these options.

Service	Name	Description
cbr	Constant Bit Rate Supports real-time applications requiring a
		fixed amount of bandwidth. The applications
		produce data at regular rates.
rtvbr	Real Time	Supports time-sensitive applications such as
	Variable Bit Rate	voice. In these applications the rate at which
		cells arrive are varied. But these cells need
		to be delivered in a timely manner with
		minimal delay.
nrtvbr	Non Real Time	Supports applications that have no
	Variable Bit Rate	constraints on delay and delay variation, but
		still have variable-rate and bursty traffic
		characteristics. Applications include packet
		data transfers, terminal sessions, and file
		transfers.
ubr	Unspecified Bit	Best effort service that does not require
	Rate	tightly
		constrained delay and delay variation. UBR
		provides

no specific quality of service or guaranteed throughput. The traffic is “at risk” because the network provides no performance guarantees for UBR traffic. The traffic descriptor is similar to IP’s “best effort” approach to traffic management.

<encaps> Specifies whether ATM Adaptation Layer is aal2 or aal5. For voice (not support by USR9003) connections, AAL2 must be specified. For data connections, AAL5 must be specified. -peak <value> Defines the fastest rate a user can send cells to the network. It is expressed in
