           "This table contains information about open virtual
            circuits (VCs) that a client has.  For point to point
            circuit, each entry represents a single VC connection
            between this client ATM address to another party ATM
            address.  In the case of point to multipoint connection
            where a single source address is associated with
            multiple destinations, several entries are used to
            represent the relationship.  An example of point to
            multi-point VC represented in a table is shown below.

            Note:  This table assumes the IP multicast address
                   groups (min, max) defined in each entry are
                   always consecutive.  In the case of that a
                   client receives a JOIN/LEAVE with
                   mars$flag.punched set, each pair of the IP
                   groups will first be broken into several
                   pairs of consecutive IP groups before each
                   entry row corresponding to a pair of IP group
                   is created."
