Swmi Initiated Group Attach/Detach; Private Call (Tmo); Terminal Ergonomic Features; Terminal Id - Motorola MTM800 Product Information Manual

Private Call (TMO)

the terminal will send an attachment of the associated group as the selected group along with the
attachment of the ATG as a scan group in addition to other scan groups it is scanning.
The TETRA TIP provides a facility by which the terminal can send a status message to the SwMI to
turn scanning off and on rather than detaching and reattaching the groups in order to save air
interface signalling.
If the terminal is provisioned with this option, when the user turns scanning off the terminal sends U-
MM-STATUS (Status Uplink set to 0x20, and Scanning On/Off set to OFF (1)). In this state the
terminal does not monitor any groups other than the selected group (this includes user scan groups,
super groups of scan groups, SwMI scan groups, ATG when an associated group is selected and
associated groups when an ATG is selected). If the user subsequently turns scanning on, the
terminal will send U-MM-STATUS (Status Uplink set to 0x20, and Scanning On/ Off set to ON (0)).
and the terminal will begin again monitoring all attached groups.
If the terminal is not provisioned with this option, the user will only have an option to deselect the
active user scan list, but will not be able to turn (all) scanning off. Deselection of the user scan list
will cause a group detachment of the user scan list groups to be sent to the SwMI; but the terminal
will continue to scan all other groups (such as ATG associations).
2.2.15

SwMI Initiated Group Attach/Detach

If the terminal receives a SwMI initiated attachment for the group which is already currently selected
the terminal will accept the attachment and keep the group selected. If the Class of Usage (CoU)
received is not "selected", that CoU will be applied when the group is deselected.
If the terminal receives a SwMI initiated attachment for a group in the currently active user scan list,
the attachment will be accepted. If it is for a group that is not in the currently the active scan list, the
attachment will be rejected. If it is for a group that is not in the currently active user scan list, the
attachment will be rejected.
SwMI initiated detachment is always accepted by the terminal. If the detachment is for the selected
group, the display will indicate to the user that no group is currently selected. If the detachment is for
a group that is in the user scan list, the group will remain in the list, but will not be monitored. If the
detachment is for a group that is in the "SwMI controlled" list, it will be removed from that list.
