Power saving mode 9 timeout
This parameter can be used to query or configure the wake up time for power saving mode 9 (see AT+CFUN with
parameter =9). The granularity of the timeout value is 100ms (i.e. a value of 10 equal 1 second). The minimum
timeout value that can be applied is 5, but accuracy is only guaranteed for timeout values greater than 20.
Parameter is global for the ME, volatile and will not be reset by AT&F.

Allowed radio band(s)
The parameters , and allow the subscriber to set and query preferences for selecting frequency
bands.
Before changing or ensure that no network activity occurs. The write command cannot be executed
when making a call, or sending / receiving short messages.
Execution of the write command causes the ME to deregister from and re-register to the network, no matter
whether the selected or setting really changes. Therefore, it is useful to have the URC "+CREG"
enabled.
The status of the SIM PIN authentication remains unchanged, eliminating the need to enter the SIM PIN again
after the change.
The parameter determines the maximum range of the bands allowed. The value may be one of the single
bands listed below or all valid combinations from the values 1, 2, 4 and 8. Thus, the value range of is
"1".."15". To select or deselect a band calculate the sum of the values of all desired bands and enter the resulting
value. For example, for 1800 MHz (2) and 850 MHz (8) please enter the value (10).
Parameter is global for the ME, non-volatile and will not be reset by AT&F.
“1“ GSM 900 MHz
“2“ GSM 1800 MHz
“4“ GSM 1900 MHz
“8“ GSM 850 MHz
“3“ GSM 900 MHz + GSM 1800 MHz
“5“ GSM 900 MHz + GSM 1900 MHz
“10“ GSM 850 MHz + GSM 1800 MHz
“12“ GSM 850 MHz + GSM 1900 MHz
“15“ all bands

Preferred radio band(s)
The parameter may be one of the single bands or one of the four dualband combinations listed below.
All preferred bands must be contained in the range of allowed bands (see ), invalid combinations are not
accepted. To give priority to a certain single band or band combination and suppress all others simply select the
same value both for and .
primarily serves to trigger the network search, i.e. it is only used one time for searching and selecting a
network. As the currently used band depends on the availability of the allowed networks the value indicated by
may be different from . Also, next time a network search is necessary, for example after restart,
the ME will first try to reselect the network last used, which may be different from the value of last given.
Therefore, the setting of will not be saved.
The value range of is "1...12", but only the bands or band selections listed below are allowed. Trying to
set an unsupported value will be denied with "ERROR". To select or deselect a band calculate the sum of the
values of all desired bands and enter the resulting value. For example, for GSM 1800 MHz (2) and GSM 850
MHz (8) please enter the value (10).
“1“ GSM 900 MHz
