Description: The number of successfully established calls detected on all signalled ATM connections on behalf of this portSelectGroup collection. Note that this value includes successfully established calls that are currently in progress. A probe should increment this counter each time a valid connection (identified with this portSelectGroup) is successfully established. For point-to-multipoint ATM connections, this counter is incremented once per counted connection, regardless of the number of leafs identified in the connection. Note that when a point-to-point connection setup enters on one port and leaves on another port in the same port select group, it is counted only once.
