zhoneSystemClockTxClockMode

The transmit clock source is provisioned in the profile
corresponding to the line type.  The choices are loop, 
local, or through.  zhoneSystemClockTxClockMode shows 
the current transmit clock source as possibly modified 
by the clock manager. If the line selected as system 
clock source is provisioned in through mode, its 
zhoneSystemClockTxClockMode value is set to loopTiming 
while it is the source.  If there is no eligible clock
source, zhoneSystemClockTxClockMode for all lines are 
set to localTiming.
              
provisionedTiming  is reserved for internal use and will
never be seen as the status of transmit clock mode.
              
localTiming indicates that a local clock source is used
or that an external clock is attached to the box
containing the interface.
              
loopTiming indicates that the recovered receive clock
is used as the transmit clock.
              
throughTiming indicates that transmit clock is derived
from the recovered receive clock of another interface.
