42.3.17 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
specic object such as an RU or a PCM line.
The functions above are normally used at

42.3.18 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 function can fail due to software incompatibility, if no RBS
conrms the connection attempt or if an OMT already is connected
(locally or remotely). In these cases the operator is informed about the
failure. No further action is taken due to the failed connection.
The connection between the RBS and a remotely connected OMT is
established on one PCM timeslot and the maximum transmission rate is
64 kbps.
42.4 Operational Conditions
The transmission rate between the OMT and the RBS is 19200 bit/s.
The IDB transfer time (between the OMT and the RBS) is specied
within the context of Installation Data Handling.
