Configuring ATM	The ATM parameters are supplied by your service provider. These
Information	parameters consist of:
	■ ATM VC information
	■ ATM Category of Service parameters
	ATM allows for permanent connections (PVCs) and switched connections
	(SVCs). For a PVC, the required VC information parameters consist of the
	Virtual Path Identifier (VPI) and Virtual Channel Identifier (VCI).
	The VPI / VCI uniquely specify the path to the remote site and are placed
	in the ATM cell header that is used to route each cell to the remote site.
	Two remote site profiles with the same VPI and VCI cannot be active
	simultaneously. You may encounter this situation if you want to log in to
	the same remote site with different PPP authentication parameters. You
	should disable all profiles using the same VPI / VCI and then enable the
	one that should be active.
	For SVCs, there is not a fixed VPI / VCI. Instead, a destination address is
	used to set up a path through the ATM backbone network when the
	connection is to be established. Currently, the SVC capability is disabled in
	the OfficeConnect Remote 840.
	ATM Category of Service parameters specify characteristics (also referred
	to as traffic shaping) of data transmitted from the OfficeConnect Remote
	840 to the remote site. They have no effect on data transmitted from the
	remote site to the OfficeConnect Remote 840.
