Alarms Possible causes

HARD_BAD Cause 1: The board and the backplane are connected improperly.

Cause 2: Board failure occurs.

Cause 3: The slot is faulty.

RADIO_TSL_HIGH ODU failure occurs

RADIO_TSL_LOW

SRP_LOC, T_F_RST T_FIFO_E, R_F_RST FIFO failure occurs

A_LOC Board failure occurs.

CONFIG_NOSUPPORT The type and configuration parameters of the ODU do not matchrequirements

RADIO_MUTE Cause 1: The other alarms are generated

Cause 2: The transmitter of the local station is manually muted

Cause 3: The IF board is faulty, causing abnormal IF output

Cause 4: The data output is abnormal because the ODU is faulty.

RADIO_RSL_LOW Cause 1: Other alarms occur at the opposite station.

2/9

Cause 2: The transmit power of the opposite station is very low.

Cause 3: The local ODU is faulty.

Cause 4: Signal attenuation on the radio link is very heavy.MW_LOF Cause 1: The other alarms are generated.

Cause 2: In the case of TDM radio services, the IF working modes at

local station and

the opposite station are different. In the case of Hybrid radio services,channel

bandwidth and modulation modes at the local station and the opposite staare different.


3/9

Cause 3: The operating frequency of the ODU at the local statioinconsistent with the operating frequency of the ODU at the opposite stat

Cause 4: The transmit unit of the opposite station is faulty.


4/9

Cause 5: The receive unit of the local station is faulty.


5/9

Cause 6: The receive power of the ODU is abnormal.


6/9

Cause 7: An interference event occurs.

MW_FEC_UNCOR Cause 1: The receive power of the ODU is abnormal.



7/9


Cause 4: An interference event occurs.MW_LIM Cause 1: The link ID of the local station does not match with the link I

the opposite

station.

Cause 2: The services on other radio links are received due to the incoconfiguration

of the radio link receive frequency at the local or opposite station.

Cause 3: The antenna receives the radio from other stations, becausedirection of the antenna is set incorrectly.

Cause 4: The polarization direction of the XPIC is incorrect.

R_LOS Cause 1: Certain alarms are generated (if the alarm is reported by aboard).


8/9

Cause 2: The line performance degrades (if the alarm is reported by anline board).



Cause 1: The negotiation fails because the transmit port and receivework in different

ETH_LOS modes.

Cause 2: The cable or fiber is faulty.

Cause 3: The opposite NE is faulty.

Cause 1: The cable is not connected or the cable is faulty.

E1_LOS

Cause 2: The opposite NE is faulty.

Cause 3: The tributary board on the local NE is faulty.


9/9

TU_AIS Cause 1: Configuration data is incorrect.

Cause 2: The line is faulty.

Cause 3: The board at the opposite end is faulty.

Cause 4: The board at the local end is faulty.
