Chapter 2 Alarm

The upstream signals sent to NR8250 equipment contains the HP-RDI signal.

The RTUB board that reports the alarm is faulty.

Handling Procedure

Check whether NR8250 uplink equipment reports alarms such as HP-UNEQ (alarm

code: 134237748), HP-TIM (alarm code: 134237751), or AU-AIS (alarm code:

134237929).

If yes, handle the alarm accordingly.

If no, go to step 2.

Ensure that the signals sent by upstream equipment to NR8250 equipment do not

contain the HP-RDI signal.

The alarm is caused by RTUB board failure. Replace the board.

2.2.23 134237929 AU-AIS

Alarm Property

Alarm Code: 134237929

Alarm Information: Every bit in the AU structure including AU-PTR is 1.

Alarm Level: Critical

Alarm Type: Communications Alarm

Sub-code Description

Sub-code 1: STM-1 of optical port 1 (LMT displays "STM-1");

Sub-code 5: Path 1 of optical port 2 (LMT displays "STM-4-Channel1");

Sub-code 6: Path 2 of optical port 2 (LMT displays "STM-4-Channel2");

Sub-code 7: Path 3 of optical port 2 (LMT displays "STM-4-Channel3");

Sub-code 8: Path 4 of optical port 2 (LMT displays "STM-4-Channel4");

Sub-code 10: STM-1 of optical port 2 (LMT displays "2STM-1").

Effect on the System

The receive signal transmitted on the SDH link is interrupted.

Possible Causes

The upstream signals sent to NR8250 equipment contains the AU-AIS signal.

The RTUB board that reports the alarm is faulty.

Handling Procedure

Check whether NR8250 upstream equipment detects the AU-AIS signal.

If yes, troubleshoot the faulty device. Replace the RTUB board.

If no, go to step 2.

The alarm is caused by RTUB board failure. Replace the board.
