rdnIfCmtsCmStatusTxUnicastExtKbytes

When read, this object will return the number of unicast 
KBytes (1024 bytes) the CMTS has transmitted to the modem 
(Downstream direction). For offline modems this value is the
the total number of unicast KBytes when it was online. This
object is never reset as long as the CMTS is up. It does not
need to be restored across reboots . However, when the CM
reregisters into a new spectrum group, this data must be
restored.
