Access classes (0 to 15) barred from network access 0 – V3.05
Description of command Sig. State
This command prevents mobile stations of definite access classes from making access attempts
when the CMU starts transmitting its BCCH channel. The 16 bit value is written to the
RACH Control
Parameter
information element and broadcast to the MS. Each true bit (no. 0 to 15, starting with the
least significant bit) means that the corresponding access class is barred.
Barring the network access is useful to establish an off-air connection to a mobile station with a
particular access class while preventing other mobiles from making access attempts. The feature is
not available in manual control. The default value (no access class barred) is restored each time the
CMU is rebooted.

Subsystem NETWork[:CSWitched]:SMODe (Type of Signalling)
The subsystem
NETWork[:CSWitched]:SMODe
defines signalling parameters concerning the function
of the mobile. The subsystem corresponds to the table section
Signalling Modes
in the
Network
tab of
the
Connection Control
menu.
