Base Station (BS) States
MFG
: Base Station defective, data cable wiring fault, or download of
software incorrect. Also a fuse on CLU/SLU is down.
PNP : Base Station is not connected, has lost power, has blown fuse
or is being downloaded.
NEW : Base Station operational but not programmed with delay or not
added into the system via CSMW.
AVE : Base Station is connected, powered and programmed.
PND : Base Station is connected, powered and programmed but must
be UTAM activated. Refer to the CSMW "Installer’s Quick
Guide" for more information.
DLU Port States
NEW
: Connected but not programmed.
PNP : Programmed but not connected.
AVE : Connected and programmed.
MFG : Port was connected and programmed but has encountered a
problem.
DTU Layer States – Layer 1 (L1)
NEW
: No physical connection to MS/PBX.
MFG : Physical link is connected, but malfunctioning or improper
signalling format
AVE : Physical connection is correct at layer 1.
DTU Layer States – Layer 2 (L2)
Only valid when layer 1 is AVE, otherwise the field of L2 remains empty.
MFG
: No multiframe synchronization received.
AVE : Multiframe synchronization received.
System Synchronization States (valid with Mobility Server only)
The system synchronization states are only applicable if the CPU is a slave CPU:
MFG
: No sync signal or not yet synchronous with the sync signal at
the CPUs sync input connection
AVE : Synchronous with the sync signal at the CPU sync input
connection.
PBX : MS number.
LinkGroup : MS connection number.
3.4 Individual User Complaints
Individual user complaints are received from only one user or, theoretically speaking, from two or
more users who are not related to each other, for example being in different areas etc.
Individual user complaints point to parts in the system that can only be accessed by that particular
Portable Telephone. These parts are the Portable Telephone itself, the charger, etc. Unlike faults,
for instance in Base Stations or system boards, which affect more than one user and mostly cause
error reports, these types of faults cannot be detected by the system simply because of their
nature. However, individual complaints are generally easy to trace.
