The ATM Virtual Circuit object describes an active virtual circuit through an ATM Port (a virtual circuit that is configured for use by an IAD, and for which the IAD is started).
There are no configurable parameters for an ATM virtual circuit, but the object provides status information about the virtual circuit. (Selecting the VPI/VCI for a particular IAD is part of the configuration of an IAD object.)
Each ATM Virtual Circuit object is a child of a Fault Tolerant ATM Port object.
Because there may be a large number of ATM Virtual Circuit objects, the EMS System Explorer displays them in groups underneath the Fault Tolerant ATM Port object. Underneath the Fault Tolerant ATM Port object there is an entry for each Virtual Path through the ATM Port. All the virtual circuits in this virtual path are underneath this entry (although they are split into further groups of up to 250 circuits if there are more than 256 virtual circuits in the virtual path.) The name shown for each ATM Virtual Circuit indicates the VPI and the VCI of the virtual circuit, for example 'ATM VC VPI=1, VCI=64'.
