Effect on the System
The carried services are affected..
Possible Causes
1.
The J1 byte received by the NR8250 is inconsistent with that sent by the upstream
equipment.
2.
The RTUB board that reports the alarm is faulty.
Handling Procedure
1.
Check whether the transmission value of
VC-4 path access point identifier (J1 byte)
of the upstream equipment and the J1 expectation value of the local equipment are
both
-ZTE-MW-NR8250-
.
l
If yes, go to step 2.
l
If no, modify the two as
-ZTE-MW-NR8250-
.
2.
The fault is caused by RTUB board failure. Replace the board.
