Communi-
cation Sub-
system
Failure
Comm_loss The connection (for manage-
ment link set-up) between the
active ANT board and the
"Board" element (redundant
ANT; TNT, AMD, IBS, CPL, coo-
ling unit, power supply unit) is
not set up or is lost.
When the alarm object is an NT,
it may mean a durable loss of
radio link.
Internal NE actions: reset
(automatic or controlled) of the
"Board" element if the board is a
TNT or AMD board or an NT.
No impact if the Board is an IBS
or X-Pol RBS board: these two
elements can continue to
function without their
management link.
The setup or re-establishment of
the connection requires the
complete (re)configuration of
this element. This procedure of
(re)confguration is automatic
and internal to the BS (as long
as all the element configu-ration
parameters are valid).
Operator action: no action.
