For those implementations who do not allow the
separate creation/deletion of the LES and BUS this
object allows the operator to specify the ATM address
of the BUS at LES creation time. For implementations
that allow separate process creation this object is
optional. Otherwise this is the ATM address of the
designated BUS. Note that setting this object will
have the side effect of reinitializing the BUS and
consequently dropping all clients connected to it. If
this object is not specified at row creation time then
the BUS will choose a value for itself and attempt to
register with the switch with that value. If an
address is specified which is not acceptable to the
switch then the busOperStatus will remain inactive
until an acceptable address is set.
