Fault List
This chapter describes faults reported to the BSC, and HW units suspected of causing the fault. Note: Note: The fault must be verifiedbefore returning the faulty unit to the Ericsson repair center. Unused fault numbers are not indicated in the fault lists.

1.1

Terminology
The following terminology is used throughout this chapter.

1.1.1

Fault Number
The fault number is identical to the bit position in the fault map reported over the Abis interface.

1.1.2

Fault Maps
Internal Fault Map Class 1A (I1A) Faultsreported in this class are faults that affect the MO function. Faulty HW is part of the signalling MO. Internal Fault Map Class 1B (I1B) Faults reported in this class are faults that affect the MO function. The origin of the fault is external to the signalling MO. Internal Fault Map Class 2A (I2A) Faults reported in this class are faults that do not affect the MO function. Faulty HW is part of thesignalling MO. External Condition Map Class 1 (EC1) Conditions reported in this class are conditions that affect the MO function. The conditions are TG external.

External Condition Map Class 2 (EC2) Conditions reported in this class are conditions that do not affect the MO function. The conditions are TG external. Replacement UnitMap (RU Map) Units reported in this map are HW units suspected of causing the faults in the internal fault maps described above.

1.1.3

Logical RU
A logical RU is defined as a unit that can be referred to, but is not a single physical unit. There are four different kinds of logical RUs. Logical RUs are pointed out when the analysis fails to give a more detailed localisation of the fault.Logical RUs are intended to assist the fault localisation process. 1. Buses. These are often referred to as a single physical unit, but are implemented in the backplane of the cabinet with cables. When a bus is pointed out in the RU map it should be understood that faulty HW can be any unit connected to the bus, or the bus itself. Logical bus RUs are: • CDU/IOM bus • EOM bus • EPC bus • PSU DC cable...
