Operation and Maintenance Terminal
28.3.12 Faults
The following user functions, related to fault information, are available
in the OMT:
• Monitor current fault status, read the fault status from the RBS
and display changes continuously.
• Display fault info, display the current fault information for a
specific object such as an RU or a PCM line.
The functions above are normally used in connection with:
• Site acceptance (monitor current fault status).

28.3.13 Work Session
The concept of Work Sessions is essential to provide easy use of the
OMT. By executing a work session, the user is guided through the
views and provided with helping instructions. A typical work session
includes all the guidance necessary for the user to complete a normal
execution of an O & M process.
There are a number of predefined work sessions included in the OMT
intended for the major O & M processes: installation test and
maintenance. Further, the customer may define his own set of work
sessions, giving maximum support to his own O & M organisation.
The following user function, related to work sessions, is available in the
OMT:
• Execute, execute a work session.
The function above is normally used for general purposes.
28.3.14 Remote OMT
A connection between the RBS and a remotely connected OMT can be
established. The remote OMT is placed at a BSC site.
The Remote OMT and the locally connected OMT are not
interchangeable with each other. They are two separate products
performing the same functions.
All functions available in a locally connected OMT are also available in
a remotely connected OMT.
The following user functions, related to the Remote OMT, are available:
• Switch CMRU to local mode, the CMRU is switched into local
operation.
• Switch CMRU to remote mode, the CMRU is switched into
remote operation.
• Reset CMRU, the CMRU is reset.
• Display CMRU operational state, the CMRU operational state is
displayed.
The functions above are used for general purposes.
