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

PNP
: Programmed but not connected.
AVE

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)

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.
