Chapter 10 – Network Service Commands
Multi-Tech Systems, Inc. CDMA C1 AT Commands Reference Guide (PN S000478C) 49
Set Uniform Out-Of-Service Values +WTUOOS
Description: This command is used to update the scan and sleep durations for the Uniform Out-of-Service
scanning algorithm. The settings are saved in non-volatile memory. The scan duration and sleep
duration are specified in seconds with values between 1 second and 32767 seconds.
Syntax: Command Syntax: AT+WTUOOS=[< scanval >], [<sleepval >]
Command Possible Responses
AT+WTUOOS=1,2 OK
Note: Command valid
AT+WTUOOS?
Note: Current values
+WTUOOS: 1,2
OK
Note: Command valid
AT+WTUOOS=? +WTUOOS: (1-32767),(1-32767)
OK
Note: Test Command
Read Result: +WTUOOS: <scanval>,<sleepval>
Values: < scanval >
1 – 32767 Uniform out of service scan value in seconds. (Default = 4 seconds)
< sleepval >
1 – 32767 Uniform out of service sleep value in seconds. (Default = 36 seconds)
Band Preference +WBND
Description: The Band Preference of a CDMA modem governs the basic system acquisition behavior of the
PRL (Preferring Roaming List). It’s important to note that the PRL takes precedence over band
preference when guiding the phone to a band. The PRL must allow a particular band first, before
the band preference can take effect. In other words, a band preference change is simply a
request; the PRL decides whether or not to allow it. If the setting is accepted by the MS, the value
will be written to non-volatile RAM and persist after a power-cycle.
The behavior of Cellular A and cellular B has changed slightly from previous Wavecom
definitions. Cellular A now means cellular A is preferred, and cellular B means cellular B is
preferred. As an example: If the device is set to cellular A, the modem will look for service on the
A side first. If service cannot be found, the modem will then check the B side for service before
reporting no service.
Note: The command may not be available in all software variations due to carrier requirements.
Syntax: Command syntax: AT+WBND=<band>,<persist>
Command Possible Responses
AT+WBND?
Note: Ask for current Band Preference
+WBND: 0
OK
Note: Any
AT+WBND=? +WBND: (0-4),(0-1)
OK
Note: Any, PCS, Cell, Cell A, Cell B
AT+WBND=0
Note: Allow Any Band
OK
Values: <band>
0 Any
1 PCS
2 Cellular A or B
3 Cellular A
4 Cellular B
<persist>
0 Do not save to NV
1 Save to NV (default)
