An address mask that when used with the
lesColocatedBusAtmAddr specifies the portion of the
BUS' ATM address desired by management. Note that
setting this object will have the side effect of
reinitializing the BUS and consequently dropping all
clients connected to it. Note that this object cannot
be set at row creation time without also supplying a
value for the lesColocBusAtmAddrSpec object. If the
BUS ATM address is omitted at creation time then this
object defaults to the value of all zeros (none of the
lesColocBusAtmAddrSpec value is relevant). If the BUS
ATM address is specified at creation time but this
object omitted, then this object defaults to the value
of all ones (all of the lesColocBusAtmAddrSpec is
relevant).
