1 Introduction
This document describes all faults reported from all Macro RBSs, except RBS
2109 and RBS 2111, to the BSC, and HW units suspected of causing the fault.
For RBS 2109 and RBS 2111, see document Fault List RBS 2000 Micro.
Note: The fault must be verified before returning the faulty unit to the Ericsson
repair centre.
Note: Unused fault numbers are not indicated in the fault list.

2 Terminology
The following terminology is used throughout this document.
2.1 Fault Number
The fault number is identical to the bit position in the fault map reported over
the Abis interface.
2.2 Fault Maps
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.
Internal Fault Map Class 1A (I1A)
Faults reported 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 the signalling MO.
Replacement Unit Map (RU Map)
Units reported in this map are HW units suspected of causing the faults in the
internal fault maps described above.
2.3 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
localization of the fault. Logical RUs are intended to assist the fault localization
process.

1. Buses. These are often referred to as a single physical unit, but are
implemented in the backplane of the cabinet or with cables. When a bus is
pointed out in the RU map it should be understood that the faulty HW can
be any unit connected to the bus, or the bus itself. Logical bus RUs are:
• CDU bus
• EPC bus/Power communication loop
• IOM bus
• Local bus
• PSU DC cable
• Timing bus
• X bus
• Y link
2. Antenna. A logical antenna means the whole signal path between the
Transmitter/Receiver and the physical antenna.
3. Environment. This RU records conditions that cannot be affected from the
base station. There are two groups under this RU:
• Power, that handles external power
• Climate, that handles internal temperature
If for example the temperature in the cabinet is too high, or the incoming
AC mains power is out of range, the logical RU "Environment" is denoted
as faulty.
4. IDB. The RBS installation database is regarded as a replaceable unit even
though it is not a physical unit. It comprises the data in the database only,
not the medium in which it resides.
