The CMU provides a softkey-oriented version of the
MS Signal
tab and a table-oriented version with
extended functionality. The
MS Signal
hotkey toggles between the two versions if it is pressed
repeatedly. For packet data mode, the two tabs provide the same settings.

PMAX
The
PMAX
parameter sets the maximum MS transmitter output power allowed in
the cell. The value corresponds to the output power at which the mobile station
performs a location update to synchronize to the CMU. It is valid both for circuit
switched and for packet data mode.

Packet Data –
Multi Slot
The
Packet Data – Multi Slot
section defines the timeslot configuration in the uplink
and downlink:
Main Timeslot
Timeslot used for signalling. The main timeslot can not be
switched off in both the downlink and uplink; see Slot
Configuration below. In Receiver Quality tests the main timeslot
is always one of the measured slots.
PCL (MS)
PCL (MS) sets (signalling states < Call Established) or changes
(signalling states Call Established) the MS output power during the connection.

Slot
Configuration
Table of all used and unused timeslots (GSM timeslots 0 to 7) in the downlink and
the uplink. The
Main Timeslot
is always active in both the downlink and uplink
direction. The boxes enable (if checked) or disable the other timeslots.
Level (BS)
RF levels in the individual downlink timeslots (RF signal
transmitted by the BS/CMU) relative to the
Reference Level
indicated above the
Slot Configuration
table and in the
BS Signal
tab (see section see section
RF Signals of the CMU (Connection
Control – BS Signal)
on p. 4.197 f.).

Channel-specific power control parameter
