Main Fan Warning
The rotation of the main fan is internally monitored and will cause a NOGO
warning if the fan is not running as expected.
The NOGO warning main fan 0103 will be sent to the remote control
system connected if the main fan of the radio is not working well.
The warning can be configured as NOGO warning in order to request a
main/standby switchover via TEST_OC X5.4.
Inactive Warning
The radio can be configured in such a way that if the radio is inactive, it
generates the CBIT Warning 0101 which is output via the remote system
connected.
User Contact Warning
The radio can be configured in such a way that a warning will be generated
if the user contact X7.15 or X11.15 is high. The USER CONTACT
WARNING 0342 or 0430 will be sent to the remote control system.
E1 RAI Warning
The transmission on the E1 interface is monitored. If errors are occurring
on the transmission system, they are indicated with an alarm indication
(RAI).
The NOGO warning E1 RAI (CBIT TX 0347 or RX 0437) will be sent to the
connected remote control system if the remote alarm (RAI) is indicated.
The warning can be configured as NOGO warning in order to request a
main/standby switchover via the TEST_OC X5.4 (TX) or X10.4 (RX).
E1 CRC4 ERROR
Warning
The bit error rate in the E1 interface is monitored. If bit errors are occurring,
they are indicated with an excessive bit error rate (CRC4) CBIT.
The NOGO warning E1 CRC4 ERROR (CBIT TX 0348 or RX 0438) will be
sent to the connected remote control system if the excessive bit error rate
(CRC4) is indicated.
The warning can be configured as NOGO warning in order to request a
main/standby switchover via the TEST_OC X5.4 (TX) or X10.4 (RX).
E1 LOS
Loss of the incoming signal of 2048 kbit/s on E1 interface.
The NoGo warning E1 LOS (CBIT TX 0345 or RX 0435) will be triggered if
the incoming signal on E1 interface is lost.
The NoGo warning can be disabled. This is useful to avoid a main/standby
switchover request via the TEST_OC X5.4 (TX) or X10.4 (RX).
E1 LOF
Loss of frame alignment and channel associated signaling (CAS) (without
recovery in timeout).
The NoGo warning E1 LOF (CBIT TX 0346 or RX 0436) will be triggered if
the frame alignment and CAS on E1 interface is lost.
The NoGo warning can be disabled. This is useful to avoid a main/standby
switchover request via the TEST_OC X5.4 (TX) or X10.4 (RX).
