Bit 1 and 2 are signaling "highly preferred", 3 and 4 are signaling "preferred", rest
is "normal". Having all 16 bits set will allow any MS to attempt registration.
The purpose is to have MS registering only with radio cells with matching
subscriber classes. I.e. a MS with class 16 - will only try to register with a cell
supporting class 16. If a MS has class 2 and class 16 it will prefer a cell with
class 2 support before looking at cells with class 16 support.
A MS has a subscriber class programmed. If in the profile setup "MS controlled"
is selected, it is the MS's programming that decides about which nodes the
terminals will try to attach to.
If defined in the profile, the MS will receive notification from the node about a
new set of subscriber classes to work with.
If defined in the profile, the shown options apply
o Call dialing
Determines whether calls uses the SSI programmed into the terminals or may
use either SSI or user numbers defined in the subscriber register.
o Use SSI for group call
This is a definition which is applicable only to the displayed information.
The function is implemented to circumnavigate differences in the way certain
brands of terminals displays the group information, for an instance Motorola
o Group talker ID
Can be selected for certain brands op terminals to display group caller ID
correctly
