48.3.3 OMT Connection
The following user functions, related to the OMT, are available in the
OMT:
• Connect, establish a connection between the OMT and the RBS.
A functionality and compatibility check is performed on RBS and
OMT software versions. If the OMT is connected remotely an
RBS address can be given in order to select one of several RBSes
connected in a multidrop chain. Also a timeslot, which the OMT
uses when established, is given by the operator. The RBS is
scanning for remote OMT link establishment on all 64 kbit/s
timeslots on PCM-A. If the RBS software does not support
scanning for remote OMT link establishment on all timeslots, the
operator has to use TS23, which is the default value. In case of
different versions the OMT operator is informed about this fact
and that all functionality is not supported.
• Disconnect, release the connection between the OMT and the
RBS.
The functions above are for general purpose use.
