The modem attempts to detect only the system in the Service ID
parameters for registration. This is useful when you want to
prevent roaming to any other system but your home system.
The modem first attempts to register on the system described by
the SPI/WASI/SPNI entries. If no system is found, the modem
attempts to register on the remaining available systems in the
area. This is useful when you spend most time in one area and
occasionally roam, or in cases where you have two systems but
prefer service on one due to, for example, rate advantages. In
these cases, enter the Network ID parameters that reflect the
system you most often will register on.
The modem attempts to register on any system but that reflected
in the Network ID entries. This is useful if you want to block
registration on systems in your area that you do not have an
agreement with. This may speed up the registration process in
some areas.
The SPI/WASI/SPNI entries are ignored. This is the default
configuration and ensures that the modem attempts to register on
any valid system that it can find.
