- DATA LINK
Emulation mode: Behaviour on DL selected from
a list of choices:-
- Analysis only: Monitoring of events on DL.
- Simulation and analysis: Simultaneous monitoring
of events and simulation on DL.
Channel specification: The TS allotment for DL
can be automatic or manual. Automatic mode has priority over manual
mode.
- Selecting IE configuration: The
number of the TS to be alloted to DL in monitoring mode is automatically
determined from the monitoring on SL of the signalling sequence.
The monitoring of a precise IE configuration can allow to determine:-
- In a first step, the Call Reference of the message including it.
- In sequence, the TS value used in the signalling sequence of the
related communication, and that results in the triggering On of
the analysis on DL defined by this way.
- in a last step, the clearing of the communication, and that results in the triggering
Off of the analysis on DL.
- TD time-slot(s) Selection of one data channel (1 - 24/31 aggregated TS)
of the TRANSMIT direction, which is alloted to DL.
- RD time-slot(s) Selection of one data channel (1 - 24/31 aggregated TS)
of the RECEIVE direction, which is alloted to DL.
Data link type: Structure of data used to record the events monitored
on DL.
In simulation mode, data type or data source used on DL.
