MC87xx Extended AT Command Reference
Note: Most carriers enable both
ciphering and integrity
(<setting> = 2).
Note: The !BAND command
shows only the bands of the
current band group (0 or 1).

g. Mark the minimum acceptable Quality of Service profile
as undefined:
AT+CGQMIN=<pid> (See 3GPP TS 27.007)
h. Mark the 3G Quality of Service profile as undefined:
AT+CGEQREQ=<pid> (See 3GPP TS 27.007)
i. Mark the minimum acceptable 3G Quality of Service
profile as undefined:
AT+CGEQMIN=<pid> (See 3GPP TS 27.007)
j. Mark PDP context parameter values as undefined:
AT+CGDCONT=<pid> (See 3GPP TS 27.007)
k. Initialize the software option byte in the profile details:
AT!SCPROFSWOPT=<pid>,0 (page 52)
(Customize configuration details)
5. If desired, assign a custom PRI part number or revision:
AT!PRIID=<priPn>, <priRev> (page 50)
6. Clear all old customizations from non‐volatile memory and
restore factory defaults:
AT!NVDEF (page 85)
AT!NVRESTORE=0 (page 86)
7. If desired, customize non‐MUX mode port mappings:
AT!NVPORTMAP=<normMode> [, <diagMode>] (page 46)
8. Set GPRS MS Class and EDGE MS Class to match network
requirements (default is Class 10, example below switches to
Class 12):
AT!NVOEM=GMSCLASS,0C (page 45)
AT!NVOEM=EMSCLASS,0C (page 45)
9. Match the modem's ciphering and integrity settings to the live
UMTS network's settings:
AT!GCIPHER=<setting> (See Supported AT reference)
10. Enable GERAN FP #1 functionality if required by carrier:
AT!NVOEM=GERANFP1,01 (page 45)
11. Configure the modem to use a specific service domain
(circuit‐switched, packet‐switched, both):
AT!SELMODE=<sdInd> (See Supported AT reference)
where <sdInd> = 0 (CS), 1 (PS), or 2 (both)
12. Choose an appropriate region‐specific scanning algorithm:
AT!CUSTOM="PRLREGION", <value> (page 33).
13. Set carrier‐specific configuration values.The following are
examples of some parameters that you may wish to
customize:
· Enable / disable ENS functionality:
AT!ENSEN=<value>
where <value> = 0 (disable) or 1 (enable)
· Enable / disable A5/2 encryption:
AT!NVOEM=GSMA5ALG=<value> (page 45)
