The default maximum number of permitted CPEs per modem
in this cable interface. A modem can override this
value by setting the object cdxCmtsCmMaxCpeNumber
in the cdxCmtsCmTable.
The value -1 means the default value of maximum hosts
per modem in this cable interface is not specified.
The value 0 means no maximum limit.
Setting the value will not affect the already connected
CPEs to the modems in this cable interface.
